Installation Guide (Linux)

PyMC Installation for Linux

We recommend using Anaconda (or Miniforge) to install Python on MacOS, which allows for packages to be installed using its conda utility.

conda create -c conda-forge -n pymc_env python pymc
conda activate pymc_env

If you like, replace the name pymc_env with whatever environment name you prefer.

JAX sampling

If you wish to enable sampling using the JAX backend via NumPyro (experimental), the following should also be installed:

pip install jax jaxlib numpyro

Similarly, to use BlackJAX for sampling it should be installed via pip:

pip install blackjax

PyMC3 Installation

The latest release of PyMC3 can be installed from Conda Forge (conda-forge):

conda install -c conda-forge pymc3 theano-pymc mkl mkl-service

Note that you must specifically request theano-pymc or you will get an obsolete version of PyMC3 that works with the now-abandoned theano library. We encourage you to test this with the --dry-run flag to ensure you get up-to-date versions.

While discouraged due to reports of installation problems you could try to install PyMC3 and its dependencies via PyPI using pip:

pip install pymc3
