Are you using NumPy <= 1.19.3 and WIndows 2004 or 20H2? If so, you should upgrade to NumPy 1.19.5. Kevin On Mon, Jan 11, 2021 at 10:51 AM Frederix96 <frederix.noel@gmail.com> wrote:

Dear numpy community,

I am having an issue with numpy.linalg where a matrix inversion of a complex matrix using numpy.linalg.inv results in containing nan values when a plot of any kind was performed beforehand by matplotlib. For the specific details on the problem and what I have tried already see the stackoverflow post I started a month ago:

https://stackoverflow.com/questions/65183984/why-does-plotting-something-wit...

I know that this problem has to do with some specifics of the maschine I am using, as it does not happen on other maschines I tried. However it still appears after rebuilding my entire python enviroment. Hence I ran out of options appart from setting up my whole PC from scratch again, which I would rather not do.

Is some problem like this known in the community?

Has anyone an idea at which other specifications of my system it might be worth taking a look at?

Thanks a lot in advance!

Best regards,

Frederix96
