This seems so obvious in retrospect, but I was able to build from source/pip by setting up a virtual environment (I use venv) using Python 3.9.13 (but not yet in 3.10) and installing from the tarball there. So, it’s very similar to the conda approach (i.e., create an environment and build within that sandbox). For some reason I continue to have trouble with conda including
ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header,
got 80 from PyObject
I just hope these comments could help someone in the future. I would love to use the mainstream Anaconda approach, but getting it to work still eludes me right now.
