Official DeepLife Python package: TwinCell (`deeplife.twincell`), pseudo-bulk (`deeplife.pseudobulk`), differential expression (`deeplife.differential_expression`). Tutorial notebooks: https://twincell.deeplife.co/docs/tutorials/ (optional `[notebook]` extra for Jupyter).
Project description
deeplife
Official DeepLife Python toolkit for TwinCell and related analysis: call the Open API from Python, pseudo-bulk with deeplife.pseudobulk, and run sample-level differential expression with deeplife.differential_expression (suitable for pseudo-bulk, bulk, or other compatible count tables). TwinCell code is split into focused subpackages under deeplife.twincell (HTTP client, workflows, preprocess, validation); deeplife.twincell itself still exposes a flat import surface for notebooks.
Source: github.com/deeplifeai/deeplife · Documentation: twincell.deeplife.co/docs · Python: 3.12+ (see pyproject.toml).
Install
pip install deeplife
API key: you need a DeepLife key (usually dl_…). Create or copy one from the TwinCell console (sign in, then open API keys / Keys). In code, set DEEPLIFE_API_KEY in the environment or pass api_key= when constructing the client. API documentation for your deployment is usually at {base_url}/docs when enabled (the client defaults to the production Open API host; pass base_url= for another environment).
Network: the TwinCell Open API is not on the public Internet today. It runs in DeepLife’s cluster and is reachable only when your machine has access to that network—for example by being signed into your organization’s Tailscale tailnet (or whatever access path your team documents). Local-only features (pseudo-bulk, differential expression on .h5ad) do not require API connectivity.

Package layout
TwinCell (deeplife.twincell)
| Import | Role |
|---|---|
deeplife.twincell |
Convenience namespace: DeepLifeClient, TwinCell, TwinCellSession, TwinCellStudy (alias of TwinCell), read_h5ad, adata_to_h5ad_bytes, etc.; lazy attributes for the heavy preprocess stack (preprocessing, pseudobulk, pydeseq2, reporting_pipeline). |
deeplife.twincell.http |
REST client (DeepLifeClient, AsyncDeepLifeClient), request/response models, errors, HTTP helpers, logging (DeepLifeClient lives in twincell.http.client). |
deeplife.twincell.workflows |
High-level session and study code: import submodules explicitly, e.g. twincell.workflows.workflows (TwinCellSession, …), twincell.workflows.study (TwinCell, …), twincell.validation.upload_helpers (adata_to_h5ad_bytes for client-side serialization), twincell.workflows.h5ad_io (read_h5ad for local paths and remote .h5ad URIs). The package __init__ resolves names lazily to avoid import cycles. |
deeplife.twincell.preprocess |
Notebook-oriented pseudo-bulk and PyDESeq2 orchestration (preprocess.preprocessing, preprocess.reporting_pipeline). |
deeplife.twincell.validation |
Local checks for the split inference upload path (validate_twincell_split_anndata, shared with the HTTP client). Exceptions live under validation.core; shared result types under validation.checks. |
Other packages
| Import | Role |
|---|---|
deeplife.pseudobulk, deeplife.differential_expression |
Pseudo-bulk from single-cell AnnData, and sample-level DE (CLIs twincell-pseudobulk, twincell-diffexpr) |
Install with pip install deeplife. Import deeplife.twincell (flat or by submodule), deeplife.pseudobulk, and deeplife.differential_expression.
Minimal API usage
End-to-end flow: prepare .h5ad or AnnData yourself → create_prediction (single file) or create_prediction_split (control + perturbed + DEGs; validated locally) → poll or watch_prediction → read results (and optional influence / causal helpers).
import os
from deeplife.twincell import DeepLifeClient
client = DeepLifeClient(api_key=os.environ["DEEPLIFE_API_KEY"])
prediction = client.create_prediction(dataset="twincell_ready.h5ad")
final = client.wait_for_prediction(prediction_id=prediction.prediction_id)
print(final.status)
The same client is available explicitly as from deeplife.twincell.http import DeepLifeClient (recommended in application code so imports stay close to the HTTP layer).
Defaults: the client uses the toolkit’s configured API base URL; pass base_url= for another environment. You must be able to reach that host from your network (see Network under Install). Retries apply to safe GET-style calls (polling), not duplicate uploads on POST. For TLS/proxy issues, use tls_verify= and trust_env= on the client—see DeepLifeClient in deeplife.twincell.http.client.
For richer AnnData preparation (QC, column mapping, pseudo-bulk), use deeplife.twincell.preprocess or the tutorial notebooks.
Tutorials
Tutorial .ipynb files are published on the docs site (interactive + download). getting-started-single-cell.ipynb covers Kang PBMC pseudo-bulk, PyDESeq2, and TwinCell target validation. getting-started-bulk.ipynb is the bulk RNA-seq companion.
Run locally from a git clone:
pip install "deeplife[notebook]" jupyterlab
git clone https://github.com/deeplifeai/deeplife
cd deeplife
jupyter lab tutorials/
Set DEEPLIFE_API_KEY (or use the notebook getpass prompt) before the TwinCell API steps. Network access to the Open API is required for those cells — see Install.

Same notebooks for local Jupyter |
Contributors can use uv sync --group dev --extra notebook instead of pip if you prefer the locked lockfile.
After
pip install -U deeplife, confirm imports match the layout you expect; the latest release is always on PyPI.
Development
uv sync --group dev
make check-all # or: ruff, mypy, pytest — see Makefile
CI: .github/workflows/ci.yml runs on pushes and PRs to main / master: uv sync --frozen --group dev, Ruff, mypy, pytest, uv build, twine check --strict. .github/dependabot.yml bumps GitHub Actions weekly.
Releases to PyPI: .github/workflows/pypi-publish.yml runs the same checks, then publishes with OIDC trusted publishing (GitHub environment pypi, trusted publisher configured on the deeplife PyPI project). Bump version in pyproject.toml, push to main, then either push a tag matching v* or run the workflow manually from the Actions tab.
