Cython compilation error with Cython>=3 and scikit-learn<1.2 #26858
Description
Workaround for this issue
➡️ The most likely reason you are reading this issue is that you are using a version of scikit-learn that does not support cython 3.0
The solution is to pin cython to cython<3 in your environment and use pip install --no-build-isolation scikit-learn to install scikit-learn.
(edit by @betatim to make the solution more visible. Please don't add a comment to this issue if all you are saying is "I also have this problem".)
Note: at the time of writing (September 2023) scikit-learn>=1.2 compiles fine with Cython 3 (latest release is Cython 3.0.2) but this can change with Cython development.
Original issue description
When installing scikit-learn==0.23.2 in a docker I get now the following error. I was not getting it ~1month ago.
I can pip install newer scikit-learn versions (i.e., 1.3.0), however, given that there is no across version compatibility my models do not work.
Thus, I'd like to ask for support to see if you knew why scikit-learn==0.23.2 can not compile and, if possible, to overcome this limitation.
