Actually it isn't necessary to install Cython above since SciPy will install its own Cython when building. The version constraint allows for 0.29.x updates though and so it will choose 0.29.31 even if cython==0.29.30 is used above: https://github.com/scipy/scipy/blob/b76137f0d4fd82bd74b2e51af33af3ece44e45bc/pyproject.toml#L1-L14
0.29.x
0.29.31
cython==0.29.30
Expected behavior
SciPy would build as it did with Cython 0.29.30
Environment (please complete the following information):
Additional context
SciPy issue: scipy/scipy#16723 SymPy issue: sympy/sympy#23847

Yeah we've been told this by SciPy. They've fixed it and we've got a PR to fit it #4929
Sorry, something went wrong.
Here's the original Scipy issue scipy/scipy#16718
Thanks. Should this be closed then or should it be kept open until the pip install above succeeds?
Probably keep it open until we've merged the PR here
Fixed in #4929 by reverting the new error.
