Running into Runtime error while trying to import eccodes

[eryk-slowinski]

Hi I am trying to import eccodes in my python code and I run into error :

    import eccodes

  File "C:\Users\admin1\anaconda3\lib\site-packages\eccodes\__init__.py", line 15, in <module>
    from .eccodes import *

  File "C:\Users\admin1\anaconda3\lib\site-packages\eccodes\eccodes.py", line 12, in <module>
    from gribapi import __version__

  File "C:\Users\admin1\anaconda3\lib\site-packages\gribapi\__init__.py", line 13, in <module>
    from .gribapi import *  # noqa

  File "C:\Users\admin1\anaconda3\lib\site-packages\gribapi\gribapi.py", line 2217, in <module>
    __version__ = grib_get_api_version()

  File "C:\Users\admin1\anaconda3\lib\site-packages\gribapi\gribapi.py", line 2207, in grib_get_api_version
    raise RuntimeError("Could not load the ecCodes library!")

RuntimeError: Could not load the ecCodes library!

Command
python -m cfgrib selfcheck
returns

Found: ecCodes v2.17.0.
Your system is ready.

I am using Windows 10 and latest relase of conda and python

The conda package 'eccodes' at the moment only includes the library itself; not its Python interface. This is sufficient to make dependencies, such as cfgrib, Magics and Metview work. To use the low-level Python API you need to install it with "pip install eccodes". Very soon the Python interface should be part of the conda install.

[eryk-slowinski]

conda install eccodes
Doesn't work for me at all. I installed eccodes via pip, as you propsed.
python -m eccodes selfcheck
returns the same error: RuntimeError: Could not load the ecCodes library!
However
python -m cfgrib selfcheck
returns

Found: ecCodes v2.17.0.
Your system is ready.

Sorry, took me a while to get a Windows machine to test. For me eccodes and cfgrib work. You say "conda install eccodes - Doesn't work for me at all." What does not work? Do you get an error when you run the install command?

[eryk-slowinski]

conda install eccodes

As with 'cfgrib' (ecmwf/cfgrib#136) 'eccodes' is only available from the conda-forge repo. As described on https://github.com/ecmwf/eccodes-python, you can install eccodes with "conda install -c conda-forge eccodes".

[eryk-slowinski]

With "conda install -c conda-forge eccodes" I have a very big error (like 1000+ lines) so I will paste only this:

Package anaconda-project conflicts for:
anaconda-navigator -> anaconda-project[version='>=0.4']
anaconda==2020.02 -> anaconda-project==0.8.4=py_0The following specifications were found to be incompatible with your CUDA driver:

  - feature:/win-64::__cuda==10.1=0
  - feature:|@/win-64::__cuda==10.1=0

Your installed CUDA driver is: 10.1

So this means I need other version of CUDA driver and anaconda?

[StephanSiemen]

I tried various versions and combinations of packages under Windows but I am not able to reproduce your error. A bit googling showed me that others (unrelated to eccodes) have challenges with conda and cuda. Could you try an conda environment without cuda?

[eryk-slowinski]

It seems like it has conflict with everything:

Package scikit-learn conflicts for:
anaconda==2020.02 -> scikit-learn==0.22.1[build='py37h6288b17_0|py36h6288b17_0|py38h6288b17_0']

Package gmpy2 conflicts for:

List like above is very long (over 6000 lines).
You think total reinstalling whole conda environment can help?

i am having same problem but using venv.
I have them installed on the environment
cycler 0.11.0 debugpy 1.6.7 decorator 5.1.1 distlib 0.3.6 earthpy 0.9.4 eccodes 1.6.1 enpt-enmapboxapp 0.7.6 entrypoints 0.4
I run the code in jupyter notebook and works, but when I run it on .py is not working.
I am using xarray so i dont need to import eccodes directly, and I got same error:
lib\site-packages\xarray\backends\plugins.py:80: RuntimeWarning: Engine 'cfgrib' loading failed: Cannot find the ecCodes library warnings.warn(f"Engine {name!r} loading failed:\n{ex}", RuntimeWarning)
If I try to explicitly import eccodes , same error

I am using vs code, on windows 11
