Thanks, Sara. Great to hear you have success.
I concur both #1 and #2 methods will install pymc on the Base Python 3.0 image, but it follows with the C-API warning upon import. Much of what I wrote above is how I resolve that warning and get it to work on Base Python 3.0 with no warnings. However, both #1 and #2 straight up fail for me on the Data Science 3.0 image.
