# PySM 3
PySM generates full-sky simulations of Galactic emissions in intensity and polarization relevant to CMB experiments. It is a large refactor of [PySM 2](https://github.com/bthorne93/PySM_public) focused on reducing memory usage, improving performance and run in parallel with MPI.
See the documentation at <https://pysm3.readthedocs.io>
## Install
### Requirements
See [requirements.txt](requirements.txt)
### Conda
conda install -c conda-forge pysm3
See the [conda repository](https://anaconda.org/conda-forge/pysm3) and the [feedstock](https://github.com/conda-forge/pysm3-feedstock)
### Pip
pip install pysm3
### Libsharp
MPI-Distributed smoothing (optional) requires libsharp, it is easiest to install the conda package:
conda install -c conda-forge libsharp=*=*openmpi*
It also has a mpich version:
