Hi,

Import error when installing UMEP for Processing on MacOS

Couldn't load plugin 'UMEP' due to an error when calling its classFactory() method ImportError: C extension: None not built. If you want to import pandas from the source directory, you may need to run 'python setup.py build_ext' to build the C extensions first. Traceback (most recent call last): File "/Users/gast/.local/lib/python3.9/site-packages/pandas/init.py", line 23, in from pandas.compat import ( File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/qgis/utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "/Users/gast/.local/lib/python3.9/site-packages/pandas/compat/init.py", line 26, in from pandas.compat.numpy import is_numpy_dev File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/qgis/utils.py", line 888, in _import mod = _builtin_import(name, globals, locals, fromlist, level) File "/Users/gast/.local/lib/python3.9/site-packages/pandas/compat/numpy/init.py", line 17, in raise ImportError( ImportError: this version of pandas is incompatible with numpy your numpy version is 1.20.1.

The above exception was the direct cause of the following exception:

Looks you have a version conflict between numpy and pandas. Try to upgrade.

Hii I have a similar issue. When I upgrade pandas to use UMEP, I was told the following and therefore cannot use UMEP for processing.

module 'numpy' has no attribute 'long'

However, if I install an older version of numpy, as I was told 'long' has been deprecated in numpy 1.20, I could not use UMEP and UMEP for processing as I need to upgrade my python libraries.

Would you know how to solve it?

Have a look at this Discussion. https://github.com/UMEP-dev/UMEP/issues/543
