Problems installing h5py / importing netCDF4

[woldmuyn]

Technical questions

• Python version: 3.10.6
• Operating System: Windows 64 bit

Description

After updating the environment, I got following errors when importing other packages in a .py file: ImportError: DLL load failed while importing _netCDF4: The specified procedure could not be found.

In a Jupiter file everything still worked fine
Probably a Windows issue

Solution

Importing netCDF4 before every other package
