Crash on UMEP plugin install

[mothlight]

Describe the bug
The install of UMEP crashes when I try to install it on Ubuntu 22.04 and QGIS 3.22.4. I'll see if I can figure out what is going on. I assume it is the older version of QGIS. It is the most recent version available for 22.04.

I was able to successfully install it on Fedora 40 and QGIS 3.34.

Couldn't load plugin 'processing_umep' due to an error when calling its classFactory() method

I can reproduce the error with the same configuration. I already had this problem in the past due to the use of Numba lib in QGIS but this was for Windows and I have never received any answer ().

However, installing QGIS and UMEP into Ubuntu 22.04 should not be an issue if you are allow and willing to use conda or mamba environments (#585 (comment)).

If so I recommend to install mamba (https://mamba.readthedocs.io/en/latest/user_guide/mamba.html) and to simply do the following in a terminal:

mamba install -n myQgisUmepEnv gdal qgis jaydebeapi "numpy<2.0.0" numba netCDF4 pandas scipy matplotlib xarray unidecode
mamba activate myQgisUmepEnv
qgis

Hello,

FYI: I got the same error message while installing UMEP_processing on Windows.

However, when cancelling the error window, the next message says the plugin was installed successfully. I restarted QGis, and both plugins are present. So I don't know whether the plugin is indeed successfully installed, or something is still missing.

As for the solution proposed by @j3r3m1, I wouldn't know how to do this on Windows, and specify a conda environment in QGis.

• Windows 11
• QGis: 3.36.3 Maidenhead
• Pyton 3.12.3
• UMEP-version: the development version sent around by Frederik on 1/11 at this link
• installing via plugin manager of QGis, option 'install from ZIP'.
  • Click Yes when asked to download extra dependencies
  • Click Yes when asked to restart QGis
  • Then I get the error message.

@bartpannemans , we are aware of this issue on some windows machines and have for a long time tried to work out a solution (not there yet). A restart should activate umep, eventhough you got an error message concerning jaydeapi.

I would NOT recommend the anaconda solution on windows. We have experienced multiple issues using anaconda/QGIS on windows over the years. Maybe it is better not so please report back your experience.

Has this been sorted out? Can I close?
