scvi-tools can be installed via conda or pip. If you don’t know which to choose, we recommend conda for beginner users.

conda prerequisites#

  1. Install Conda. We typically use the Miniconda Python distribution. Use Python version >=3.7.

  2. Create a new conda environment:

    conda create -n scvi-env python=3.9
  3. Activate your environment:

    conda activate scvi-env

pip prerequisites#

  1. Install Python, we prefer the pyenv version management system, along with pyenv-virtualenv.

  2. Install PyTorch. If you have an Nvidia GPU, be sure to install a version of PyTorch that supports it – scvi-tools runs much faster with a discrete GPU.


conda install scvi-tools -c conda-forge


pip install scvi-tools

Through pip with packages to run notebooks. This installs scanpy, etc.:

pip install scvi-tools[tutorials]

Nightly version - clone this repo and run:

pip install .


For development - clone this repo and run:

pip install -e ".[dev,docs]"


scvi-tools can be called from R via Reticulate.

This is only recommended for basic functionality (getting the latent space, normalized expression, differential expression). For more involved analyses with scvi-tools, we highly recommend using it from Python.

The easiest way to install scvi-tools for R is via conda.

  1. Install Conda Prerequisites (see above).

  2. Install Reticulate:

  3. Then in your R code:

    use_condaenv("scvi-env", required=TRUE)
