Greetings,
I hope this message can reach the right person. I'm trying to run the notebook for seasonal forecast anomalies
https://ecmwf-projects.github.io/copernicus-training-c3s/sf-anomalies.html
Unfortunately, I get the below error. I've been trying to solve this for a long time. I had this bug on mac and recently on a new windows computer. Have you experienced this before? if so, could you please help me to solve this problem?
Thank you very much,
Carlo

    Hi Carlo!

    is it ecCodes installed in your system? have the notebook cells installing and importing the relevant modules run properly on your notebook?

    Have a look at the system dependencies section here: https://pypi.org/project/cfgrib/0.8.4.5/

    Regards!

    Edu

      Thank you Edu,
      Yes, I have ecCodes installed.

      python -m cfgrib selfcheck
      Found: ecCodes v2.24.2.
      Your system is ready.

      I'm not sure about the dependencies, I'm on a windows machine and the instructions are for linux and mac only. Also, this link is broken https://software.ecmwf.int/wiki/display/ECC/ecCodes+installation
      Any ideas?
      Thank you!
      Carlo

        I'm sorry I can't help you further.

        If no other users can provide helpful feedback... have you tried contacting User Support? http://support.ecmwf.int

      Do you get the same error also when you run the script from the terminal? Try checking if Jupyter is using the right kernel (the one with cfgrib installed). 

      Also, have you tried installing cfgrib both with conda and pip? 

  2. Carlo Montes

    thank you for the clues

    I'm using a base kernel, I wasn't able to find the kernel cfgrid installs

    I ran it as a py file and I got the same error

    1. Matteo De Felice

      So, if you open a python terminal and you type import cfgrib you don't get any errors?

    same thing. But it seems eccodes is the problem
