Default solver (pypardiso) not working on AMD cpus

[weishiyu1]

I have encountered such a problem (AttributeError: module 'openpnm' has no attribute 'models') when I import openpnm. How can I solve it?

It might just be a corrupt installation. Try re-installing openpnm.

@weishiyu1 Thanks, this seems to be different error, right? You previously reported Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.. Is that correct or am I missing something?

This is another running environment. You can ignore it. After configuring the environment and install openpnm package according to previous prompts, when it runs to the flow.run() , no other errors are displayed, just showed Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll, and then it ends the operation.

Hmm, does it say which line the error comes from?

[weishiyu1]

There is no prompt on which line the error is, only Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll was displayed. It should be that the program has terminated, but according to my judgment, it might be come from flow.run().

Could you try to run only the following script and see what error (if any) you're getting?

import pypardiso
import numpy as np
import scipy.sparse as sp
A = sp.rand(10, 10, density=0.5, format='csr')
b = np.random.rand(10)
x = pypardiso.spsolve(A, b)
