"Preparing metadata (pyproject.toml) ... error" on Raspberry Pi 5

[technofox01]

I am trying to install the lastest version of fastsdcpu on my Raspberry Pi 5 8GB and I keep getting this error message:

Can someone help with this?

It's been driving me nuts.

I am using Debian 12 (bookworm) and have Python 3.11.2 installed.

Hi!

This worked perfectly, thank you. Quick question, are you able to add support for OnnxStream?

Source:
https://github.com/vitoplantamura/OnnxStream

It works so much faster on Raspberry Pi 5 than the methods used by Fastsdcpu. It just lacks a functional webui. I appreciate your thoughts.

@technofox01 Thanks for using FastSDCPU, i will check that

@technofox01 how much time onnxstream takes to generate image on RPI 5? which model?
