# Installation

We recommend using [Anaconda](https://www.anaconda.com/) (or [Miniforge](https://github.com/conda-forge/miniforge)) to install Python on your local machine, which allows for packages to be installed using its `conda` utility.

Once you have installed one of the above, PyMC can be installed into a new conda environment as follows:

```console
conda create -c conda-forge -n pymc_env "pymc>=4"
conda activate pymc_env
```
If you like, replace the name `pymc_env` with whatever environment name you prefer.

issues when using multiple conda channels (e.g. defaults and conda-forge).

## JAX sampling

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

```console
pip install numpyro
```

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

```console
pip install blackjax
```

Note that JAX is not directly supported on Windows systems at the moment.
