`ImportError` On clean installation in virtual enviroment
Describe the bug Running
import exoplanet as xo
Trigger an ImportError with trace
ImportError: dlopen(./exoplanet/lib/python3.9/site-packages/netCDF4/_netCDF4.cpython-39-darwin.so, 2): Library not loaded: @loader_path/libzip.5.5.dylib
Referenced from: ./exoplanet/lib/python3.9/site-packages/netCDF4/.dylibs/libnetcdf.19.dylib
Reason: no suitable image found. Did find:
./exoplanet/lib/python3.9/site-packages/netCDF4/.dylibs/libzip.5.5.dylib: cannot load 'libzip.5.5.dylib' (load command 0x80000034 is unknown)
./exoplanet/lib/python3.9/site-packages/netCDF4/.dylibs/libzip.5.5.dylib: cannot load 'libzip.5.5.dylib' (load command 0x80000034 is unknown)
To Reproduce The only code run is
python3.9 -m venv exoplanets
python3.9 -m pip install -U "exoplanet[extras]"
and then
import exoplanet as xo
Expected behavior To import the package
Your setup (please complete the following information):
- Version of exoplanet: latest (0.5.3)
- Operating system: macOs (python venv)
- Python version & installation method (pip, conda, etc.): python 3.9.12, installed throught pip
Additional context None
This is an issue with the installation of netCDF4 (which is an indirect dependency via arviz), rather than exoplanet directly. I've also previously found that the pip binary wheel for mac is broken and fixed it by installing netCDF4 with conda (conda install -c conda-forge netcdf4), but there might be other ways to get an installation that works!
