Poll: What's in your .pytensorrc file? (or PYTENSOR_FLAGS variable)

Hi All,

I’m on Windows and have usually installed pymc with pip and used my own gcc. I rarely installed via conda like is recommended. I’ve been curious if I’ve really been missing out on better performance with MKL vs OpenBLAS that is packaged with numpy on PyPi. I’m comparing a pip install and conda install right now (exactly according to instructions). I want to make sure I’m setting the right blas flags in .pytensorrc so it’s configured correctly.

I have tried:

[blas]
ldflags = -lmkl -lguide -lpthread

OR

[blas]
ldflags=-lblas

without much difference.

I want to see what you are all using. Could you fill out:

OS: Windows, Mac, Linux flavor
Install method: Conda/Pip
Known/Unknown BLAS used with Numpy:
.pytensorrc file:
```
[blas]
ldflags=-lblas
```

For what it’s worth, this is my numpy.show_config() for my pip installation:
