Started with the IOOS environment. pip install XROMS and $ pip3 install --upgrade roguewave
If doing it again, should add pip to environment.
Installed wavespectra...that worked, but now using new code, so have to run it locally.
It seems to need netcdf4<1.6.0, so downgraded many pkgs with mamba "install netcdf4<1.6.0" xarray was producing NaN's, did a mamba update netcdf4`
