cannot get master branch to run under python 3.7? #393

Closed tt-aqt closed 4 years ago

tt-aqt commented 4 years ago

There's something about scipy it doesn't like? some problem with the iir?

I'm using the default python 3.7 found on raspbian buster with full updates. I think pyqt5 is already installed since "import PyQt5" does not give an error message.

EDIT: this turned out to be a raspian problem, not a pyrpl problem. I uninstalled pyrpl and scipy, then installed scipy using the raspian package manager.

pip3 uninstall scipy pip3 uninstall pyrpl sudo apt install-y python3-scipy

Then I reinstalled pyrpl, and everything worked.
