Why does kernel die after executing command for reading grib2 file with xarray with engine cfgrib

Question

I am using a jupyter notebook running on Ubuntu18 OS with Python3

After executing the command

import xarray as xr
import pyeccodes
import eccodes 
import cfgrib
my_data = xr.open_dataset('mydata.grib2' , engine='cfgrib')

The kernel dies.

I think the issue is related with grib files with different typeOfLevel (see this issue)
