issue with running the notebook related to impact functions

[sunt05]

Hi, I'm trying to run the notebook associated with #692 but can't move forward.

I followed this guide for the installation of CLIMADA. Below is the version info:

CLIMADA Version: 4.1.0
python: 3.9.18

The issue was occurring while importing climada:

import logging
import climada

logging.getLogger("climada").setLevel("WARNING")

Error message below (Click to expand)

The issue seems to be related to an upstream package.

Thanks for reporting this @sunt05.
In order to run this notebook you will eventually have to switch to the "advanced installation" method, as you will need to install climada from sources (from the calibrate-impact-function branch, to be more precise).

However failing at the import climada step cannot be attributed to the "simple installation" approach!
Usually this happens because the ipykernel is wrong. Have you checked that?

[peanutfun]

@sunt05 This looks like a mismatch between the versions of dask and pandas. As @emanuel-schmid already mentioned, you need to follow the Advanced Installation Instructions for running the script from #692. In step 4, replace

git checkout develop

with

git checkout calibrate-impact-functions

and continue with the instructions. Following them will not install Jupyter into the environment, so you can then choose to install Jupyterlab or install the more lightweight Jupyter with

mamba install -n climada_env jupyter

You should then be ready to execute the tutorial. In any case, you should choose the Conda environment of Climada as Kernel when you run Jupyter.

Please report back if the problem persists when following these instructions. In this case, we might need to update the environment specifications.

[sunt05]

Many thanks for the guidance above.

However, I now encounter a new error when running verification after installing climada, which should be addressed as numpy 2.0 has been formally released:

python -m unittest climada.engine.test.test_impact

[emanuel-schmid]

Many thanks, @sunt05! This is unexpected, normally numpy 1.xx is bein installed. I suppose you can workaround by running

mamba install numpy=1.26

Meanwhile we have to investigate this and likely update the environment file. To speed this up, could you perhaps post the output of

mamba repoquery whoneeds numpy

here?

[sunt05]

Please see below for the output of mamba repoquery whoneeds numpy:

Using local repodata...

Loaded current active prefix: "/Users/tingsun/micromamba/envs/climada_env"

No entries matching "numpy" found

numpy may not be installed. Try giving a channel with '-c,--channel' option for remote repoquery

From the above error message, it looks like the issue was caused by xarray.

[sunt05]

Also, after downgrading numpy to 1.26, a new issue related to cartopy and shapely appeared when running the test python -m unittest climada.engine.test.test_impact:

[emanuel-schmid]

Er - sorry - but that doesn't look good. In particular the output of mamba repoquery is inexplicable. I'm afraid something went wrong with the installation. At this point I'd suggest to restart from scratch. Do cd <path/to/workspace> and run

cd climada_python
git checkout calibrate-impact-functions
git pull origin calibrate-impact-functions
mamba env remove -n climada_env
mamba create -n climada_env python=3.9
mamba env update -n climada_env -f requirements/env_climada.yml
mamba activate climada_env
python -m pip install -e "./[dev]"

If you get an error for any of the commands, please post the command and error output here.
If all goes smoothly, run the mamba repoquery whoneeds numpy command again and post the output.

[sunt05]

Thanks for updated instructions.

@sunt05 This still does not look right. Note that the traceback shows that the dask module loaded by your interpreter is located in /Users/tingsun/.local/lib/python3.9/site-packages/dask/ (your default interpeter location, I presume), and not in the Mamba environment /Users/tingsun/micromamba/envs/climada_env.

It seems you are using Micromamba, and we have no experience with its particular behavior. Can you switch to Conda or Mamba?

[sunt05]

I see - thanks for pointing that out - will switch now and update you shortly.

[sunt05]

Thanks for the above instructions - I just managed to install the package and run the entire impact notebook.

One suggestion for the installation instruction is to change the recommended Python version from 3.9 to 3.11, as the latter has better compatibility for ARM64 Mac. Python 3.9 has various issues due to several packages lacking ARM libraries for legacy reasons.

I'll now close this issue and move forward with the review task.

[emanuel-schmid]

👍 Glad it worked out. Thanks for the suggestion. We wanted to do that anyway, eventually. Considering your input this should happen rather sooner than later.
