scvi-tools (single-cell variational inference tools) is a package for probabilistic modeling and analysis of single-cell omics data, built on top of PyTorch and AnnData.

Analysis of single-cell omics data

scvi-tools is composed of models that perform many analysis tasks across single- or multi-omics:

• Dimensionality reduction
• Data integration
• Automated annotation
• Factor analysis
• Doublet detection
• Spatial deconvolution
• and more!

In the user guide, we provide an overview of each model. All model implementations have a high-level API that interacts with scanpy and includes standard save/load functions, GPU acceleration, etc.

Rapid development of novel probabilistic models

scvi-tools contains the building blocks to develop and deploy novel probablistic models. These building blocks are powered by popular probabilistic and machine learning frameworks such as PyTorch Lightning and Pyro. For an overview of how the scvi-tools package is structured, you may refer to this page.

We recommend checking out the skeleton repository as a starting point for developing and deploying new models with scvi-tools.

Basic installation [Abstra]

Clone repository

git clone https://github.com/owkin/deepdeconv-fork # https
git clone git@github.com:owkin/deepdeconv-fork.git # ssh

Create an environment and install scvi-tools locally

conda create -n deepdeconv python=3.9
conda activate deepdeconv
cd deepdeconv-fork
# install library in editable mode
pip install -e ".[dev,docs,tutorials]"
# Install additional requirements
pip install -r requirements.txt

To confirm that scvi-tools was succesfully installed

pip show scvi-tools

Create an ipykernel so you can use your environment with a Jupyter notebook

`python -m ipykernel install --user --name=deepdeconv`

Create a branch for local development

git checkout -b {your-branch-name}

I you want to use a GPU, make sure to create a workspace with a GPU in Abstra. Please be sure to install a version of PyTorch that is compatible with your GPU (if applicable).
