Issue loading CBLAS library

General
1

Dear all,

My name is Antonio Garcia-Uceda, and I’m a researcher on Flux Reconstruction methods. I’m using pyFR as part of my project.

I’m trying to run pyFR with backend “opemp”, but I’m coming across some issues when using a CBLAS library. I get the following error message on the screen:

Let me know if you know the source of the problem. Thanks a lotin advance.

Best regards,

Antonio

Hi Antonio,

My psychic debugging skills suggest that the version of NumPy you are
using is older than 1.8. PyFR requires NumPy 1.8 or later to function.

Hi Freddie,

I confirm your phyco debugging skills, :), thanks a lot once more.

Btw, have you ever run the Euler case Ringleb Flow with pyFR?

Best regards,
Antonio

Hi Antonio,

I have no experience with this particular test case.
