eccodes 2.38.3

System dependencies

The Python module depends on the ECMWF ecCodes library. From version 2.37.0, this is supplied with the Python module. If you wish to install and use a separate binary library (see above), it must be installed on the system and accessible as a shared library.

On a MacOS with HomeBrew use:

$ brew install eccodes

Or if you manage binary packages with Conda use:

$ conda install -c conda-forge eccodes

As an alternative you may install the official source distribution by following the instructions at https://confluence.ecmwf.int/display/ECC/ecCodes+installation

You may run a simple selfcheck command to ensure that your system is set up correctly:

$ python -m eccodes selfcheck
Found: ecCodes v2.37.0.
Your system is ready.

Refer to the ecCodes documentation pages for usage.
