possible explanations to investigate are:

• [ ] 'jinja2<=3.0.3', in xsar/setup.py
• [ ] 'numpy<=1.21', # numba needs numpy<=1.21 in xsarsea/setup.py

if opencv is installed via conda. The problem is different: First thtere this pip error:

Successfully built xsarsea
Installing collected packages: typer, numpy, llvmlite, numba, cftime, netCDF4, xrft, xsarsea
  Attempting uninstall: numpy
    Found existing installation: numpy 1.23.4
    Uninstalling numpy-1.23.4:
      Successfully uninstalled numpy-1.23.4
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
xsar 0.9.1 requires jinja2<=3.0.3, but you have jinja2 3.1.2 which is incompatible.
Successfully installed cftime-1.6.2 llvmlite-0.39.1 netCDF4-1.6.2 numba-0.56.4 numpy-1.21.0 typer-0.7.0 xrft-1.0.0 xsarsea-0.3.dev56+g0ccc3e3

then import xsarsea works. while import xsar never ends (strace last hints is pointing to cartopy). tested on a ubuntu 22.04 and python 3.10 conda env.

this issue seems to be solved with #42
