The recipe for installing 3rd party libraries (like scipy) seems to be changing from one release to another. I have spent a couple of days trying to install scipy into blender python on the latest release (3.3.1). None of the methods from older versions seem to work.
I have tried the recommendations from this answer:
And, this answer:
None of these seem to work.
I also tried copying the scipy folder from system’s site-packages to the blender’s Python lib folder. But it doesn’t work either.
P.S. I think there should be documentation on how to achieve this (within the release notes or a forum post) that tracks this for each release. A lot of people seem to be running into this.
