I haven't used pyXSIM in quite a while, so did a clean installation, and if you install the module on a clean conda environment using the conda release the module is unusable due to a failure on import.
This failure occurs because the unyt module is not installed, which in turn happens because pyXSIM requires YT > v4.0 and the conda installation allows it to install v3.6 of YT.
