Errors running SignalIntegrity GUI Python 3.12, numpy==2.0.0

After installing Signal Integrity App and trying to run, getting the following error message:

Running Ubuntu Linux 24.04, Python 3.12, Numpy numpy==2.0.0, SignalIntegrityApp 1.4.1

Searching online, seems Numpy 2.0 has deprecated .math part of the library. Perhaps that can be the reason?

[dracid]

Seems like the following several files need to be edited to import "pi" instead of "math" and it works great after:

[Phi-sqrd]

@dracid , your initial post suggested modifying only the use of pi, but on my system (macOS Monterey 12.3.1), I found it necessary to update both pi and sqrt to maintain functionality.

Changes Made

I modified the following five files, which are named after the functions defined within them:

SeriesRse.py
SeriesL.py
SeriesC.py
TerminationC.py
TerminationL.py

In each file:

• Removed the import statement for math.
• Imported pi and sqrt directly from numpy.

from numpy import pi
from numpy import sqrt

• Replaced instances of math.pi and math.sqrt with the newly imported pi and sqrt.

Thanks to @dracid for the fix! the App works!

[dracid]

Thanks, glad this helped!! I hope I can create a pull request :)) Need to learn how to do this.

My bad, you are totally right --> math.sqrt also had to be replaced.

[Phi-sqrd]

That was incredibly helpful @dracid ! Thank you so much. I'm really looking forward to trying out the code with your PR.
