SciPy/NumPy/Python version information

1.9.1 1.23.3 sys.version_info(major=3, minor=9, micro=12, releaselevel=‘final’, serial=0)

[andyfaff]

There are no windows 32-bit wheels for 1.9.2. I think Tyler was suggesting pip install scipy --only-binary=:all:. If you transition to 64-bit Python you shouldn’t have a problem upgrading to 1.9.2

[andyfaff]

Good.
