Unittest climada.engine.test.test_impact fails

[agcclimate]

Describe the bug
I followed the simple installation instructions for Windows using miniforge prompt. After activating the cliamda environment, the unittest fails, showing the following error: TypeError: descriptor 'call' for 'type' objects doesn't apply to a 'property' object

To Reproduce
Steps to reproduce the behavior/error:

1. mamba create -n climada_env -c conda-forge climada
2. mamba activate climada_env
3. python -m unittest climada.engine.test.test_impact

Code example:

(climada_env) C:\Users\agarciac>python -m unittest climada.engine.test.test_impact

Expected behavior
The test should pass and display an "Ok!"

Screenshots

Climada Version: 5.0.0

System Information (please complete the following information):

• Operating system and version: Windows 11
• Python version: 3.11
  (to obtain this information execute > import sys >print(sys.version))

Additional context
Add any other context about the problem here.

Could you specify the full python version? Is it >=3.11.9 ?

[spjuhel]

This is very probably the same problem as in #943, and related to dask/dask#11038

The current best course of action would be to downgrade python to < 3.11.9, assuming you are on >= 3.11.9.

Please confirm this solves your problem and close the issue if that is the case.

[alessioic]

I have the same issue. I downgraded Python to 3.11.8, but the problem persists.

[spjuhel]

Ok, I will try to reproduce and see what works on my side, in the meantime:

Did you a) use a fresh python 3.11.8 environment or b) update an already existing one?

If b) could you try a)?
And if a) could you try with python 3.10?

Could you also tell me whether you use conda or mamba and which version you use? As well as your operating system?

[spjuhel]

Ok so, running the following installs python 3.11.6 (Trying with 3.11.8 fails to solve dependencies with gdal) and works on my side (Ubuntu 22.04 - mamba 1.5.5 - conda 23.11.0)

mamba create -n climada_env -c conda-forge "python<3.11.9" climada
mamba activate climada_env
python -m unittest climada.engine.test.test_impact

[alessioic]

Great! It works. Many thanks

[agcclimate]

It also works on my end. I uninstalled python without noticing the version but I assume it had to do with it. Many thanks!
