AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

PyTDC is a tool-integration skill for the Therapeutics Data Commons (TDC) library. It enables researchers to discover therapeutic ML tasks, load curated datasets, apply task-specific data splits, and utilize standardized evaluators and molecular oracles. The skill emphasizes a metadata-first approach, requiring explicit user approval before performing network-intensive operations like downloading datasets, model checkpoints, or benchmark archives. It includes bundled scripts for safe metadata discovery, data loading, and bounded molecular scoring, ensuring reproducibility and controlled resource usage in scientific workflows.

What it does

  • Discovers therapeutic ML tasks, datasets, and benchmark groups via metadata queries.
  • Loads datasets with task-appropriate splitting methods like scaffold or cold-split.
  • Provides standardized evaluator metrics for model performance assessment.
  • Supports bounded molecular-oracle scoring for drug-likeness and synthetic accessibility.
  • Enables benchmark group evaluation with support for leaderboard-style aggregation.
  • Facilitates safe, isolated execution of data-intensive tasks with explicit approval.

When to use it

  • When working with therapeutic ML datasets or benchmarks from the Therapeutics Data Commons.
  • When you need to perform task-aware data splitting for molecular or biological data.
  • When evaluating generative models using standardized molecular oracles or metrics.
  • When you require a reproducible environment for scientific data access and model evaluation.

Advantages

  • Promotes reproducibility through pinned dependencies and explicit versioning.
  • Prevents accidental large-scale downloads by separating metadata discovery from data execution.
  • Provides standardized, domain-specific evaluation metrics for therapeutic tasks.
  • Includes safe, bounded CLI tools for common research operations.
  • Supports complex splitting strategies tailored to molecular and drug-discovery data.

Usage examples

“List the available ADME datasets in PyTDC.”
The agent executes a metadata-only discovery script to return a list of ADME-related datasets without downloading any data.
“Load the Caco2_Wang dataset and apply a scaffold split.”
The agent prepares a plan to load the dataset and perform a scaffold split, requiring user confirmation before the actual download and processing occur.
“Calculate the QED score for the SMILES string CCO.”
The agent uses the local QED oracle to compute the drug-likeness score for the provided molecule.
“Evaluate my model predictions against the admet_group benchmark.”
The agent validates the prediction format against the benchmark requirements and, upon approval, performs the evaluation using the official TDC metrics.

PyTDC (Therapeutics Data Commons)

Use the official PyTDC distribution (import tdc) to discover therapeutic ML tasks, load approved datasets, apply task-appropriate splits, evaluate predictions, and work with curated benchmark groups. Prefer package metadata over copied dataset lists, and plan network/storage effects before constructing any loader.

Verified snapshot

  • Research date: 2026-10-01

  • PyPI stable: PyTDC 1.1.15, released 2025-03-31

  • Package/source repository: mims-harvard/TDC

  • Code license: MIT

  • PyPI supplies only a source distribution and declares no Requires-Python

  • The dependency graph makes CPython 3.11 the reproducible target used here: cellxgene-census==1.15.0 excludes Python 3.12, and PyTDC's constrained RDKit release has no CPython 3.13 wheel

  • PyTDC imports deprecated pkg_resources at runtime. Setuptools 82 removed that module; pin the verified compatibility release setuptools 80.9.0.

  • tdc.readthedocs.io still identifies itself as TDC 0.4.1; use it as API cross-reference, not as release-version evidence

  • Upstream publishes no GitHub tags/releases or maintained changelog. Treat undocumented migration claims as uncertainty and verify against the installed 1.1.15 source/metadata.

See references/sources.md for dated evidence and known documentation conflicts.

Installation

Use an isolated CPython 3.11 environment and pin the reviewed snapshot:

uv venv --python 3.11 .venv-pytdc
uv pip install --dry-run --python .venv-pytdc/bin/python \
  "setuptools==80.9.0" "PyTDC==1.1.15"
uv pip install --python .venv-pytdc/bin/python \
  "setuptools==80.9.0" "PyTDC==1.1.15"

The current macOS ARM64 test resolution installed 128 packages, including large scientific/ML dependencies, so the environment itself can transfer and occupy hundreds of megabytes before any dataset is downloaded. Review the dry run and available disk first. The direct pins identify the reviewed API snapshot; generate a platform-specific uv.lock in the user's project when every transitive version must also be frozen.

For an ephemeral command:

uv run --no-project --isolated --python 3.11 \
  --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/discover_metadata.py --kind tasks

To check for a newer release, inspect the PyPI release history at https://pypi.org/project/pytdc/. Before changing the pin, compare its source distribution, dependencies, official repository, task registries, and smoke tests; do not silently substitute the separate pytdc-nextml package.

Non-negotiable data and network policy

  1. Discover first. Reading tdc.metadata or using scripts/discover_metadata.py does not instantiate a loader or download data.

  2. Plan second. Record the exact task/dataset, official task page, license, expected size, cache directory, split, metric, and reproducibility seed.

  3. Confirm the authorized scope before downloading. Loader constructors fetch missing data. Some datasets and benchmark-group archives are large; model-backed oracles can fetch checkpoints; remote/docking oracles can transmit molecular structures.

  4. Execute within that scope. In bundled CLIs, --execute acknowledges execution and --download is additionally required for MolGen corpora or supported oracle checkpoints.

  5. Keep outputs bounded. Emit counts, schema, and small previews rather than full datasets, sequences, prediction arrays, or molecule corpora.

Cache and cost behavior

  • Ordinary loaders default to path="./data" and save files beneath that path. The bundled scripts instead default to explicit .pytdc-* directories.

  • Core downloads use Harvard Dataverse file endpoints when a local filename is absent. Newer resource classes may use other upstream services.

  • admet_group(path=...) and other benchmark-group constructors download and extract the group archive when <path>/<group> is absent.

  • Download-backed Oracle(...) construction uses ./oracle internally. The bundled oracle CLI changes into a safe runtime directory before approved calls.

  • PyTDC 1.1.15 does not provide a universal cache quota, eviction policy, or dataset-wide checksum manifest. Use scripts/cache_audit.py and manage disk retention explicitly.

  • Network transfer, local storage, decompression, parsing, feature generation, docking, and external service calls can all incur time or monetary cost.

The PyTDC code is MIT. Dataset/task licenses are heterogeneous: official task pages include per-dataset terms ranging from Creative Commons licenses to non-commercial restrictions or “Not Specified.” Verify the exact dataset's page and original source terms before download, redistribution, publication, or commercial use. Cite both TDC and the original dataset.

Start with metadata-only discovery

From this skill directory:

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/discover_metadata.py --kind datasets --task ADME --limit 50

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/discover_metadata.py --kind benchmarks --limit 50

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/discover_metadata.py --kind evaluators --limit 100

The package API is also metadata-only:

from tdc.utils import retrieve_dataset_names, retrieve_benchmark_names

adme_names = retrieve_dataset_names("ADME")
admet_benchmarks = retrieve_benchmark_names("admet_group")

Use exact returned names. PyTDC performs fuzzy matching internally, but explicit matching avoids silently selecting the wrong dataset/oracle.

Dataset workflow

Plan a split without downloading:

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/load_and_split_data.py \
  --task ADME --dataset Caco2_Wang --method scaffold \
  --seed 42 --data-dir .pytdc-data

After the user approves the dataset, license, transfer, and storage:

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/load_and_split_data.py \
  --task ADME --dataset Caco2_Wang --method scaffold \
  --seed 42 --data-dir .pytdc-data --execute

Verified public import patterns include:

from tdc.single_pred import ADME, Tox
from tdc.multi_pred import DDI, DTI
from tdc.generation import MolGen, Reaction, RetroSyn

Constructors perform data access, so do not run them before approval:

data = ADME(name="Caco2_Wang", path=".pytdc-data")
frame = data.get_data(format="df")
split = data.get_split(
    method="scaffold",
    seed=42,
    frac=[0.7, 0.1, 0.2],
)
# split keys are: train, valid, test

For multi-label data, discover retrieve_label_name_list("tox21") and supply --label-name NR-AR (or the selected exact target) to the loader helper. Read references/datasets.md before choosing a task or dataset. The PrimeKG resource has a different artifact and a lossy to_nx() conversion; inspect the resource caveat there before building a graph.

Split selection without overclaiming leakage control

  • random: default for loaders; default seed 42 and fractions 0.7/0.1/0.2.

  • scaffold: documented generic support for molecule-based ADME, Tox, and HTS. PyTDC groups RDKit Bemis–Murcko scaffold strings (chirality disabled), but that does not prove absence of analog, duplicate, label, temporal, or provenance leakage.

  • cold_split: multi-instance API. Pass exact dataframe columns, for example method="cold_split", column_name=["Drug", "Target"]. Multi-column splitting can discard cross-partition rows and need not preserve requested row fractions.

  • combination: built-in DrugSyn combination split.

  • time: pair-loader API requiring time_column; the verified built-in case is BindingDB_Patent with its Year column. The API spelling is time, not temporal.

Do not use undocumented cold_drug_target, temporal, or stratified=True examples. For every split, record PyTDC version, parameters, row counts, and exact entity overlap audits. PyTDC 1.1.15's random splitter uses the supplied seed for test sampling but a fixed random_state=1 for validation sampling; do not describe all partitions as independently varying with the seed.

Detailed semantics and caveats are in references/utilities.md.

Evaluators

Use exact names from the installed evaluator registry:

from tdc import Evaluator

mae = Evaluator(name="MAE")(y_true, y_pred)
auroc = Evaluator(name="ROC-AUC")(y_true_binary, predicted_scores)
pcc = Evaluator(name="PCC")(y_true, y_pred)

PCC is the registered Pearson-correlation name; Pearson is not. Multi-class registry names are micro-f1, macro-f1, and kappa. Thresholded binary metrics default to 0.5. PR@K and RP@K also default to 0.5 through Evaluator; pass threshold=0.9 explicitly for a target of 90%. pr-auc is average precision. kl_divergence is a higher-is-better transformed similarity score; FCD direction depends on its backend in this release (see the utilities reference). Metric direction and input shape are metric-specific; use the official task/benchmark metric rather than choosing from task type alone.

Benchmark groups

Use specialized classes. Top-level from tdc import BenchmarkGroup is retained only as a deprecated compatibility path in 1.1.15.

from tdc.benchmark_group import admet_group

# Run only after approval: construction may download the group archive.
group = admet_group(path=".pytdc-benchmarks")
benchmark = group.get("Caco2_Wang")
train_val = benchmark["train_val"]
test = benchmark["test"]
train, valid = group.get_train_valid_split(
    seed=1,
    benchmark=benchmark["name"],
    split_type="default",
)

For one run, group.evaluate({name: test_predictions}) returns metric results. For leaderboard aggregation, pass a list of at least five prediction dictionaries to group.evaluate_many(...). These must represent independent model runs, not five copies of one prediction vector. Preserve the exact test-row order and identify each run’s training/split seed. Report the returned standard deviation as run-to-run variability, not a confidence interval on generalization performance. Do not index group.get(...) by seed, and do not derive dummy predictions from test labels. See the TDC leaderboard guide.

Use scripts/benchmark_evaluation.py to validate a bounded JSON prediction plan before any group download. See references/utilities.md for the exact JSON shape and API behavior.

Molecular generation and oracles

PyTDC supplies molecule corpora, evaluators, and oracles; it does not train or provide a generic molecule generator in the core workflow. Discover current names:

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/discover_metadata.py --kind oracles --limit 100

Plan bounded local QED scoring:

uv run --no-project --isolated --python 3.11 --with "setuptools==80.9.0" --with "PyTDC==1.1.15" \
  python scripts/molecular_generation.py score --oracle QED --smiles CCO

Add --execute only after review. LogP and SA call the downloadable fpscores artifact in 1.1.15; they and DRD2/GSK3B/JNK3/CYP3A4_Veith also require --download. The helper intentionally refuses remote services, docking, distribution, and composite oracles. It preserves input order, flags invalid/empty structures with a null score, and never assumes score direction.

Read references/oracles.md before any oracle call.

Splits, evaluators, and benchmark groups

This reference describes behavior verified in the PyTDC 1.1.15 source distribution on 2026-10-01. The official website documents user-facing intent; source inspection resolves exact method spellings and edge cases.

Split API overview

Ordinary loaders return:

{
    "train": train_frame,
    "valid": validation_frame,
    "test": test_frame,
}

The key is valid, not val. Generic defaults are:

split = data.get_split(
    method="random",
    seed=42,
    frac=[0.7, 0.1, 0.2],
)

Fractions are train/validation/test and should be finite, non-negative, and sum to one. Upstream does not consistently validate this before arithmetic; the bundled CLI does.

Loader-specific methods
Loader familyVerified methodsAdditional arguments
Single predictionrandom, scaffold, internal cold_<entity>none
Pair prediction (DTI, DDI, etc.)random, cold_split, entity aliases such as cold_drug, combination, timecolumn_name, time_column
General multi-prediction framerandom, cold_split, combinationcolumn_name
MolGen, Reaction, RetroSynrandomnone
Benchmark train/validgroup metadata chooses scaffold, random, combination, or groupbenchmark, split_type, seed

The generic official cold-start spelling is:

split = data.get_split(
    method="cold_split",
    column_name=["Drug", "Target"],
    seed=42,
    frac=[0.7, 0.1, 0.2],
)

Inspect data.get_data().columns first. A DTI frame commonly uses Drug and Target, but other tasks have different entity names. Prefer cold_split with explicit columns over inferred aliases.

Random split details

create_fold:

  1. samples test rows with random_state=seed;

  2. samples validation rows from the remainder with fixed random_state=1;

  3. assigns remaining rows to train;

  4. resets partition indices.

Consequences:

  • the supplied seed changes test membership;

  • it does not independently seed validation sampling;

  • integer rounding and Pandas sampling can make exact counts differ from naïve multiplication;

  • a different seed is not a guarantee that every partition changes.

Record content hashes or stable IDs when exact split reproducibility matters.

Scaffold split details

The official generic documentation limits scaffold split to molecule-based single-instance ADME, Tox, and HTS tasks. In 1.1.15 the implementation:

  • requires RDKit;

  • parses the configured molecular entity as SMILES;

  • computes Bemis–Murcko scaffold strings with includeChirality=False;

  • groups rows by exact scaffold string;

  • shuffles large and small scaffold groups with seed;

  • greedily assigns whole groups to partitions;

  • omits SMILES that raise during scaffold generation.

The requested row fractions are targets, not guarantees, because whole scaffold groups are assigned together. “Scaffold split” means exact computed scaffold groups do not cross partitions in that implementation. It does not establish that:

  • close analogs or similar scaffolds cannot cross;

  • duplicates, labels, assay batches, sources, or dates are isolated;

  • stereochemistry is isolated;

  • invalid/missing structures are represented;

  • preprocessing performed before splitting did not leak information.

Audit exact structures, scaffolds, identifiers, labels, provenance, and temporal fields appropriate to the scientific question. Use cautious language such as “partitioned by PyTDC's 1.1.15 Murcko-scaffold implementation,” not “leakage-free.”

Cold split details

cold_split samples unique values independently for each requested column, then:

  • keeps test rows satisfying all sampled test-entity memberships;

  • removes any row containing a test entity from the train/validation pool;

  • samples validation entity values from the remainder;

  • keeps validation rows satisfying all validation memberships;

  • removes validation entities from train.

For multiple columns this intersection/removal process can discard many cross-combination rows, produce empty validation/test partitions, and yield row fractions far from frac. PyTDC raises ValueError when test or validation is empty.

Exact values in each requested column are designed to be disjoint across returned partitions. That is a narrow entity-overlap property, not proof against:

  • aliases or duplicated entities with different identifiers;

  • homologous targets or structurally near-identical compounds;

  • shared higher-level groups;

  • preprocessing or label leakage.

The bundled loader CLI reports pairwise exact-value overlap counts for requested columns without making a broader claim.

cold_drug_target is not a 1.1.15 method. Use:

data.get_split(
    method="cold_split",
    column_name=["Drug", "Target"],
    seed=42,
)

Combination and time splits

Combination

The built-in combination implementation is designed for DrugSyn data with Drug1_ID, Drug2_ID, and Cell_Line_ID. It separates drug-pair combinations across partitions while representing cell lines.

In 1.1.15 it adds an internal concat column and does not remove it consistently from every returned partition. Inspect schemas rather than assuming identical columns. Do not apply it generically to DDI or DTI.

Time

Pair loaders use:

split = data.get_split(
    method="time",
    time_column="Year",
    frac=[0.7, 0.1, 0.2],
)

The verified built-in dataset case is DTI(name="BindingDB_Patent"), whose loader adds Year. The implementation sorts by the time column and returns an additional split_time summary. It does not use seed.

The spelling temporal is unsupported. Time boundaries can contain ties and the implementation uses boundary comparisons, so inspect timestamps and counts.

stratified=True is not a supported get_split argument in these loaders.

Evaluator registry

Discover exact names from the installed package:

python scripts/discover_metadata.py --kind evaluators --limit 100

Verified scalar registry names include:

roc-auc, f1, pr-auc, precision, recall, accuracy,
mse, rmse, mae, r2, pcc, spearman,
micro-f1, macro-f1, kappa, avg-roc-auc,
rp@k, pr@k, range_logAUC

Generation/distribution names include:

novelty, diversity, uniqueness, validity, fcd_distance, kl_divergence

Coordinate names include rmsd and kabsch_rmsd. Metadata also lists smina, but the 1.1.15 Evaluator.assign_evaluator implementation does not bind an evaluator function for it; treat Evaluator("smina") as an unresolved upstream inconsistency, not supported usage.

Always pass exact registry names. Fuzzy matching exists, but aliases such as Pearson, Micro-AUPR, and Macro-AUPR are not registered.

rmsd, kabsch_rmsdpaired coordinate arrayslower

This table describes evaluator semantics, not every benchmark's leaderboard objective. Use bm_metric_names or the official benchmark page for the chosen benchmark. Never infer a dataset's metric from “classification” or “regression” alone.

Call behavior
from tdc import Evaluator

mae = Evaluator("MAE")(y_true, y_pred)
auroc = Evaluator("ROC-AUC")(y_true_binary, predicted_scores)
spearman = Evaluator("Spearman")(y_true, y_pred)

Thresholded accuracy, precision, recall, and f1 default to 0.5 and convert scores with score > threshold; a score exactly equal to the threshold becomes class 0. PR@K and RP@K default to 0.5 through Evaluator, overriding the underlying functions' 0.9 default. Pass threshold=0.9 explicitly when desired. Spearman returns only the correlation coefficient from SciPy's result.

pr-auc calls scikit-learn average_precision_score, not trapezoidal PR-curve integration. avg-roc-auc averages over axis 0 (one AUC per row/sequence), so transpose task matrices only when that matches the intended unit of averaging. range_logAUC defaults to FPR range (0.001, 0.1); the public wrapper does not forward FPR_range. Likewise Evaluator("kabsch_rmsd") performs rotation without centroid translation and ignores a translate keyword; center paired coordinates first or call tdc.evaluator.kabsch_rmsd(P, Q, translate=True) directly.

kl_divergence averages ten exp(-KL) terms over molecular descriptors and internal similarity. Higher means closer distributions; it is not raw KL. Unpatched 1.1.15 also imports removed scipy.histogram: KL fails on the tested modern SciPy stack. A test-only alias to numpy.histogram reproduced the intended transform, but is not an upstream fix or a supported unpatched workflow. Its KDE can fail for tiny, constant, or singular samples. fcd_distance tries TensorFlow/FCD first, returning exp(-0.2 * raw_FCD) (higher is closer), then falls back to PyTorch/fcd_torch, returning raw FCD (lower is closer). Record the selected backend and transformation; do not compare these values directly or infer direction from the registry name. Optional FCD models were source-verified only, not downloaded/executed in this refresh.

Validate lengths, shapes, label encoding, missing values, score calibration, and class presence before calling. ROC-AUC is undefined when only one class is present.

BenchmarkGroup API

Public specialized imports in 1.1.15 are:

from tdc.benchmark_group import (
    admet_group,
    docking_group,
    drugcombo_group,
    dti_dg_group,
)

The generic top-level import is deprecated:

# Compatibility only; emits a deprecation message.
from tdc import BenchmarkGroup

Use a specialized class. Construction can download and extract an entire group archive:

from tdc.benchmark_group import admet_group

group = admet_group(path=".pytdc-benchmarks")

Do this only after user approval.

Retrieve fixed test and train/validation data
benchmark = group.get("Caco2_Wang")
name = benchmark["name"]
train_val = benchmark["train_val"]
test = benchmark["test"]

train, valid = group.get_train_valid_split(
    seed=1,
    benchmark=name,
    split_type="default",
)

There is no general get_test() method in 1.1.15. group.get() returns train_val, test, and normalized name. get_train_valid_split reads the downloaded train/validation file and applies group metadata. The held-out test set is fixed. The base splitter uses [0.875, 0.125, 0.0] of train_val for ordinary train/valid splits; the group path instead holds out 0.2 within Year. With zero test fraction, the random path's fixed validation seed makes its split identical across the requested seeds. Vary model training seeds independently.

One-run evaluation

Predictions must align exactly with the downloaded test-frame row order:

predictions = {name: y_pred_test}
result = group.evaluate(predictions)
# {normalized_name: {metric_name: value}}

Do not include test labels as model features, generate predictions from test labels, or tune against repeated test evaluations.

Multi-run aggregation
prediction_runs = [
    {name: y_pred_seed_1},
    {name: y_pred_seed_2},
    {name: y_pred_seed_3},
    {name: y_pred_seed_4},
    {name: y_pred_seed_5},
]
summary = group.evaluate_many(prediction_runs)
# {normalized_name: [mean, population_standard_deviation]}

Single-run scores are rounded to three decimals before evaluate_many computes population standard deviation (ddof=0), then rounds the aggregate to three decimals. Retain raw per-run metric values separately when more precision matters. evaluate(testing=False) references an undefined true variable in 1.1.15; use an explicit Evaluator on validation labels instead.

The input is a list of per-run dictionaries, not {seed: predictions} and not a benchmark object indexed by seed. Non-docking groups require at least five runs. The 1.1.15 implementation returns a ValueError object instead of raising when fewer are supplied; the bundled CLI validates count first.

The official guidance calls for at least five independent runs. A seed should control model initialization, stochastic training, and the train/validation split where the upstream splitter actually uses it. Report every seed and protocol.

Bundled benchmark JSON

Plan mode never constructs a group:

python scripts/benchmark_evaluation.py \
  --group admet_group --dataset Caco2_Wang

Single-run input:

{
  "caco2_wang": [0.1, 0.2, 0.3]
}

Multi-run input:

{
  "runs": [
    {"seed": 1, "predictions": {"caco2_wang": [0.1, 0.2]}},
    {"seed": 2, "predictions": {"caco2_wang": [0.1, 0.2]}},
    {"seed": 3, "predictions": {"caco2_wang": [0.1, 0.2]}},
    {"seed": 4, "predictions": {"caco2_wang": [0.1, 0.2]}},
    {"seed": 5, "predictions": {"caco2_wang": [0.1, 0.2]}}
  ]
}

The CLI bounds input size/run count/value count, rejects non-finite numbers, duplicate normalized names, unequal benchmark sets or per-benchmark run lengths, and verifies test-row counts before scoring. It requires --execute before group construction. It intentionally excludes docking_group because that path can invoke docking, receptor downloads, molecular filters, and optional external services.

Requirements and compatibility

Works with: Claude Code, Claude apps, OpenAI Codex, GitHub Copilot, Cursor, Gemini CLI, Kiro, OpenCode, Goose, Amp, Roo Code, JetBrains Junie, Factory Droid, Devin (ex-Windsurf), Mistral Vibe, OpenHands, Letta

“Works with” means the tool reads the open Agent Skills format; a skill written for one tool may use features others lack.

Needs: Declares allowed tools, Needs network access, Needs Python
