=====================

Not sure what to try next. Any ideas?

I appreciate your time and help.

Which scipy version are you using? It seems I have used a deprecated function that is no longer supported in your scipy version. Please try to downgrade your scipy version and tell me whether that works for you. I'll replace the function in my next release.

1st - Thanks for your help.
2nd - Yup - I had scipy 1.8.0 installed.
When I downgrade to 1.7.3 all works as expected.

[chipmuenk]

Thanks, I'll leave the issue open as a reminder.

@chipmuenk same here, fresh venv on ubuntu 20.04 and pip install pyfda installed with it scipy 1.8.0. Downgrading to 1.7.3 did the trick.

Hi
I have the exact same issue, also on a windows machine.

Here's some system info

λ  python --version
Python 3.10.2

λ  python -m pip list | grep scipy
scipy               1.8.0

λ  python -m pip list | grep pyfda
pyfda               0.6.0

I'll take a look at downgrading scipy.

[chipmuenk]

Fixed in v0.6.1

[Hagtronics]

Checked install today with both versions of Scipy (1.7.3 and current 1.8.0) and it works for me. Thanks for the unbelievably useful program.

[g-berthiaume]

Same thing here. Everything seems to be working.
