Preparing metadata (pyproject.toml) did not run successfully. (release 1.0.0) (maybe NUMPY 2.0.0 problem)

[bsimmo]

Just setting up a nice new PiZero 2 using 32bit bookworm (lite) because I had a nice email this new version had been released :-)

Using Raspberry Connect - terminal to do all the remote stuff, but used SSH before that. Only other extra program installed is git itself (it's not installed by default on lite) and of course RPi Connect

Just flagging this up, could be your problem, or it might not be. I get the error twice, first in initial setup and then when it tries to get example dependencies.

Is this because Numpy is too new (2.0.0 has only just been released six days ago, 17th Jun 2024)

It seems PiWheels cannot cope with NUMPY 2.0.0 on Python 3.11 either, hence it's trying to build. https://www.piwheels.org/project/numpy/

[bsimmo]

So NUMPY 2.0.0 is fixed on Piwheels now https://github.com/piwheels/packages/issues/456 Ben fixed it for us.

Sorted, all installs fine.
