• I read the conda-forge documentation and could not find the solution for my problem there.

Issue:

See conda-forge/eccodes-feedstock#120 for all the details.

Something has changed in the conda-forge ecosystem in the last 24 hours that is causing some solvers to choose eccodes 2.19.1 when installing python-eccodes. Before that eccodes 2.20.0 was being used and works fine. However, with 2.19.1 I get:

>       from ._bindings import ffi, lib
E       ImportError: /usr/share/miniconda3/envs/test-environment/lib/python3.8/site-packages/gribapi/_bindings.cpython-38-x86_64-linux-gnu.so: undefined symbol: codes_bufr_key_is_header

/usr/share/miniconda3/envs/test-environment/lib/python3.8/site-packages/gribapi/bindings.py:29: ImportError

Forcing the eccodes version to 2.20.0 or above seems to have fixed things.
