All the tests involving CHOWTapeModel.component fail #32

Closed LucaMarconato closed 2 years ago

LucaMarconato commented 2 years ago

I have create a conda environment, installed pybind11 and tox via conda and run tox. But all the tests involving CHOWTapeModel.component fail.

Some more details (please tell me if you want more information):

Any idea?

psobot commented 2 years ago

Hi @LucaMarconato! I do indeed more information - what errors do the tests fail with? Any useful stack traces or error messages?

psobot commented 2 years ago

Hi again @LucaMarconato - just an FYI that I'm going to close this in a week if it's no longer an issue, as I don't really have any information to go off of (and I've been unable to reproduce the issue).

LucaMarconato commented 2 years ago

Hi, sorry for the delay in answering, here is my full output from tox, do you need any extra information, like the full conda environment info?

Thanks @LucaMarconato! A couple more things to try:

HussainAbdi commented 2 years ago

Hi again @psobot! I ran into the same issue as @LucaMarconato and thought I could help answer these questions. I am running on a M1.

HussainAbdi commented 2 years ago

After adding CHOWTapeModel.component to ~/Library/Audio/Plug-Ins/Components/, all these component test cases pass. Not sure why, but I've left it there for now.

HussainAbdi commented 2 years ago

FYI for anyone facing this issue, I had the same problem on a non-M1 MacBook Pro (2016 13-inch MBP) and it was resolved the same way as above. Adding CHOWTapeModel.component to ~/Library/Audio/Plug-Ins/Components/.

psobot commented 2 years ago

Thanks @HussainAbdi and @LucaMarconato! I'm adding a change to fix these tests and raise a more descriptive ImportError if the plugin fails to load. It seems that on M1, or in certain unknown configurations, plugins are required to be installed to ~/Library/Audio/Plug-Ins/Components or they'll fail to load.
