ContextualVersionConflict: (scikit-learn 0.22.2.post1 (/usr/local/lib/python3.6/dist-packages), Requirement.parse('scikit-learn[alldeps]>=0.23'), {'pysindy'})[BUG] about pysindy

Restarting the runtime fixes this issue, though I am not sure about the causes of it.

The alldeps warning comes from the following line in the requirements file: scikit-learn[alldeps]>=0.23. The alldeps option is supported for Scikit-learn version 0.23, but not 0.24. It simply ensures that all of sklearn's dependencies are installed along with it. I think you can safely ignore this warning.

I still suspect the ContextualVersionConflict is caused by the fact that the system has sklearn version 0.22 installed, while newer versions of PySINDy require version 0.23. Installing PySINDy version 0.15 probably worked because it required an earlier version of sklearn.

My guess is that this is due to the recent update to the requirements file to require scikit-learn version 0.23 or greater. Does updating to scikit-learn version 0.23 fix the problem?

I faced the same issue as well. Restarting runtime in colab fixed it. I am not sure what causes it. I tried to install sklearn with [alldeps] and pysindy was giving me the same error.

Just curious, which issue of sklearn do you have installed?

[ConstantinosM]

Colab comes with sklearn 0.22.2.post1 pre-installed. If I install pysindy (pip install pysindy) then it gives me a warning that sklearn requires alldeps. Then when I import pysindy and try to use it I get the same error as above (which is fixed if runtime is restarted). I installed other versions of sklearn (from 0.22 up to the latest one with/without [alldeps] argument) but stil I got this error. Only pysindy==0.15 did not have any issue at all and no warnings when installing it.

I am adding a screenshot when installing pysindy in Colab
