2 months ago Current latest version available via pip is 'netCDF4==1.7.1.post1'. To get 'netCDF lib >= 4.9.0', there are development install instructions but seem quite cumbersome
Clone the github repository. Make sure you either clone recursively, or run git submodule update --init to ensure all the submodules are also checked out.
Make sure the dependencies are satisfied (Python 3.8 or later, numpy, Cython, cftime, setuptools, the HDF5 C library, and the netCDF C library). For MPI parallel IO support, an MPI-enabled versions of the netcdf library is required, as is mpi4py. Parallel IO further depends on the existence of MPI-enabled HDF5 or the PnetCDF library.
By default, the utility nc-config (installed with netcdf-c) will be run used to determine where all the dependencies live.
If nc-config is not in your default PATH, you can set the NETCDF4_DIR environment variable and setup.py will look in $NETCDF4_DIR/bin. You can also use the file setup.cfg to set the path to nc-config, or enter the paths to the libraries and include files manually. Just edit the setup.cfg file in a text editor and follow the instructions in the comments. To disable the use of nc-config, set the env var USE_NCCONFIG to 0. To disable the use of setup.cfg, set USE_SETUPCFG to 0. As a last resort, the library and include paths can be set via environment variables. If you go this route, set USE_NCCONFIG and USE_SETUPCFG to 0, and specify NETCDF4_LIBDIR, NETCDF4_INCDIR, HDF5_LIBDIR and HDF5_INCDIR. If the dependencies are not found in any of the paths specified by environment variables, then standard locations (such as /usr and /usr/local) are searched.
if the env var NETCDF_PLUGIN_DIR is set to point to the location of the netcdf-c compression plugins built by netcdf >= 4.9.0, they will be installed inside the package. In this case HDF5_PLUGIN_PATH will be set to the package installation path on import, so the extra compression algorithms available in netcdf-c >= 4.9.0 will automatically be available. Otherwise, the user will have to set HDF5_PLUGIN_PATH explicitly to have access to the extra compression plugins.
run pip install -v . (as root if necessary)
run the tests in the 'test' directory by running python run_all.py.
Seems a different netCDF library is required but not sure how to install it. Error message has a version requirements which should already be met. Also seems the library is needed for some compression (zstd, blosc_*)
