What is your issue?

I was getting the following error continuously when using xarray.open_mfdataset: bash ValueError: did not find a match in any of xarray's currently installed IO backends ['netcdf4', 'h5netcdf', 'scipy', 'cfgrib', 'pydap', 'zarr']. Consider explicitly selecting one of the installed engines via the ``engine`` parameter, or installing additional IO dependencies When the file file was indeed a netcdf4: bash $ ncdump -k myfile.nc classic I was running my script with the command inside a docker container, which uses a different user and group than myself. It seems the issue was on the permisions of the file as only my user had access: bash $ ls -la total 39M -rw-r----- 1 borja borja 39M Mär 23 12:15 myfile.nc Changing permission rights with chmod a+r myfile.nc solved the thing: bash $ ls -la total 39M -rw-r--r-- 1 borja borja 39M Mär 23 12:15 myfile.nc The permission thing is perfectly fine, it was my error, however, it would be nice that the command open_mfdataset (or related) would raise PermissionError when permissions are not sufficient.
