wrf-python installed from conda-forge produces import error

Riproduci l’installazione conda-forge su Windows 7 con il comando riportato python -c "import wrf". Leggi wrf/__init__.py e wrf/config.py intorno all’importazione di _wrffortran, quindi confronta il pacchetto conda con il wheel funzionante; il lavoro è completato quando l’installazione conda esegue l’importazione e legge un file NetCDF wrfout senza l’errore DLL.

Installed wrf-pyhton through conda-forge on windows 7 64 bit. Post installation, checked if the package is installed correctly using following command:-

 python -c "import wrf"

and it worked without an error. However, when I ran the script the following error is produced:-

Python 3.7.6 (default, Jan  8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

>>> import wrf

During handling of the above exception, another exception occurred:

ImportError: DLL load failed: The specified path is invalid.

I am not sure what causes the problem. Could someone help on this t rectify...

Edit:-

Just to clarify that the same works on Linux version of miniconda.

Edit-2

Uninstalled latest version of wrf-python and installed older version (1.3.0). This time I am getting following error:-

Traceback (most recent call last):
  File "insdvp_app.py", line 30, in <module>

Fiddled around with package from https://www.lfd.uci.edu/~gohlke/pythonlibs/. This time it successfully installed (version 1.2.0 as it was the latest at that point of time) and imported without an error. However, while reading the wrfout file, the script closed without producing an error.

To check if the problem exist in window 10, I installed the module on a freshly installed miniconda. This time it did not show any error as I have observed in windows 7. However, It simply closes without producing any error when reading a wrfout netcdf file as seen in latest try on windows 7.

Checked the wheel package today again at https://www.lfd.uci.edu/~gohlke/pythonlibs/#wrf_python and found the latest version 1.3.2. Uninstalled the conda version and installed whell package from link. Finally, It worked :-)

Something is wrong with conda install on windows. You guys may want to chack it out...
