Blas version the pytorch uses

deployment
1

Is there any way to check which Blas lib pytorch uses in the runtime? Is it MKL or OpenBlas?

I checked the loaded dll, and find both MKL and openblas lib there.

import torch
print(*torch.__config__.show().split("\n"), sep="\n")

PS: this works for PyTorch 1.1 or earlier.
