# Installation with conda from conda-forge¶

We provide a package for the [conda] package manager in the conda-forge channel, so you can install TeNPy as:

conda install --channel=conda-forge physics-tenpy


Following the recommondation of conda-forge, you can also make conda-forge the default channel as follows:

conda config --add channels conda-forge
conda config --set channel_priority strict


If you have done this, you don’t need to specify the --channel=conda-forge explicitly.

Moreover, it is actually recommended to create a separate environment. To create a conda environment with the name tenpy, where the TeNPy package (called physics-tenpy) is installed:

conda create --name tenpy --channel=conda-forge physics-tenpy


In that case, you need to activate the environment each time you want to use the package with:

conda activate tenpy


The big advantage of this approach is that it allows multiple version of software to be installed in parallel, e.g., if one of your projects requires python>=3.8 and another one requires an old library which doesn’t support that. Further info can be found in the conda documentation.
