Eventually I was able to solve this problem, but in a weird way…
I first created a new environment (distinct from my base one), say PyMC_env:
(base) PS C:\Users\thaly> conda create -c conda-forge -n pymc_env “pymc>=4”
(Don’t ask me where I found the statement used… I don’t remember)
Then I opened a Jupyter notebook and change the Kernel from Python 3 (ipkernel) which in the default in my installation, to pymc_env and than ran the code shown in the Oriol Unraveled web page, case: 1st example: rugby analytics, using statement import pytensor.tensor as at instead of import aesara.tensor as at, as I already explained above.
Now, running the code generates a series of pop-up error warnings, just as the one displayed in the image below:
I just click on the OK button and let the things go. Amazingly, I counted 8 such pop-ups appearing successively, displaying each time a different try_blas_*****.exe line (I mean, the characters in ***** are always changing…).
I click on OK every time, until the pop-ups stop appearing…
Then, the code ends up executing to completion, and I am able to get the plots by the usual az.plot_trace(rugby_idata)…
I do not understand anything. It ends up working, that’s good, but what do these pop-up windows mean, for example try_blas_on24wqw9.exe and all the others?
Why do they appear, and why do they stop appearing?
I have:
