I have installed ecCodes library with 

pip install eccodes

When I check it with 'pip list' it seems like it is installed as 0.9.7 ver but command:

python -m eccodes selfcheck

Returns error 

RuntimeError: Could not load the ecCodes library!

The same error occurs when I try to import eccodes. I am using Windows 10 and Python 3.7.6 Any thougths what is wrong?

Full error:

import eccodes

  • Is that the entire error output? A quick google search for that error message returns some relevant results, have you already consulted all of those? – AMC Apr 15 '20 at 21:18

    I have edited post and added full error output. Nothing of the solutions on google was useful for me – Słowik Apr 15 '20 at 21:21

    Did you ever resolve this issue by chance? I am getting the same error and cannot resolve. – cgage1 Dec 24 '20 at 17:27

The python package eccodes is only a binding to the C library eccodes made by ECMWF.

https://confluence.ecmwf.int/display/ECC/ecCodes+installation

As you can read on this website, they do not support Windows.

Advise from me: you won't get happy reading grib files (and working with meteorological data in general) on Windows. You could consider using Ubuntu or another Linux distro, maybe also just on a VM.

There is a conda package eccodes for the C library:

conda install -c conda-forge eccodes

Alternately, you can install those outside of your conda environment, for example, by compiling from source.

Then there is a pypi package eccodes that contains only the Python bindings:

pip install eccodes

You need both! From your error message, it seems that you have the Python bindings, but not the underlying C library.

For more (slightly dated) information, see the ECMWF Confluence wiki:

The 'ecmwflibs' library install will help.

pip install ecmwflibs

import ecmwflibs

import eccodes
