Python: failed to load package on path

Question

I am trying to install the cfgrib using pip using the following:

pip3 install --user eccodes

This installs the eccodes package along the following path:

/Library/name/Python/3.8/lib/python/site-packages

When I try to run my python script (see below) I get an error message telling me:

UserWarning: Failed to load cfgrib - most likely there is a problem accessing the ecCodes library. Try `import cfgrib` to get the full error message

import numpy as np
import xarray as xr
import matplotlib.pyplot as plt
import cfgrib

path = '/Users/name/Library/Python/3.8/bin'
fname = 'download.grib'

ds = xr.open_dataset(path+fname,engine = 'cfgrib',backend_kwargs={'indexpath':''})

Does anyone know how to solve this?

Answer 1

Try

pip install ecmwflib

It worked for me.
