cfl error in merging_glaciers notebook

[pat-schmitt]

On the website a cfl error occurs in the merging_glaciers notebook. But I could not reproduce the error locally, not sure how to proceed.

Can you try to set cfl_number to 0.01?

I also could not reproduce with cfl_number 0.01 locally. I also created an env with the same oggm version as is used on mybinder and was not able to reproduce the error. Maybe there is something going on in the docker image. I can try to run the notebook from the image to reproduce the error.

ah and before this I test also with python 3.10

You can also try to push cfl to 0.01 in a PR and trigger a build online, but the problem is that we won't know what the problem is.

Maybe something in the output changed again :cry:

ok python 3.10 was not the problem. What do you mean with pushing cfl to 0.01? I tested on my binder with cfl 0.01 and the tutorial still fails.

Ah ok ok - great thanks.

Another solution would be to simplify this example or remove it, but that's some work or a bit sad,
