Question

How can I ensure and confirm that the SciPy package I installed has pythran optimized functions available? I am installing python 3.9.5 from python software foundation website, using PyCharm IDE for package management that uses pip to set up packages.

If you've used pip to install the SciPy 1.7.0 wheel from PyPI, it will have the Pythran modules included by default (the extensions can be excluded by setting the environment variable SCIPY_USE_PYTHRAN=0 when building).

>>> import scipy.interpolate._rbfinterp_pythran
>>> help(scipy.interpolate._rbfinterp_pythran)
