Loading Models

[matthewkeck]

Hello,

Thank you for making this repository it has been really helpful. I have encountered an issue when trying to load the custom models I receive this error message.

From my reading online it looks like there has been changes to how models have been saved and loaded in the past. Thank you for your time.

Sorry I it looks like issue #27 has the fix.

Hi. I get the same error. Where can I find issue #27 for the resolution? KR Thomas

[matthewkeck]

its the first issue in the closed section. The #27 should be a link to it.

Found it. I am also using a Pi5. Will have to downgrade, I guess.

If I remember right the guy in the issue had to downgrade. I am running a Pi4 and it works for me. It might be worth setting up a docker container.
