Show warning on mac when custom pip package path is not writable

[cornerfarmer]

See https://github.com/DLR-RM/BlenderProc/pull/767#issuecomment-1332331345

On Mac OS, you have to add in the general settings that your terminal is allowed to perform updates. Else it can not execute the pip installs. That is interesting.

Maybe we should add a warning if:

PermissionError: [Errno 1] Operation not permitted: '/Users/max/blender/blender-3.3.0-macos-x64/Blender.app/Contents/Resources/custom-python-packages'

I am getting the same error, has someone found a solution to this?

Did you try to add in the general settings that your terminal is allowed to perform updates.?

[ShreyaKapoor18]

@cornerfarmer I did add this, and was able to install.

I made a virtualenv and install h5py with brew but now when I do blenderproc quickstart

I get an error 'no module named h5py'

[cornerfarmer]

Probably h5py is not found inside blenders python environment. Usually this should be installed automatically on the first run, but could you try installing it manually via:

blenderproc pip install h5py

@cornerfarmer Hi and thank you for your reply. I ran this command, it did install h5py After this I ran blenderproc quickstart

but this resulted in the same error h5py not found

@cornerfarmer I met the same error and I think I know what you mean. But how to "add in the general settings that your terminal is allowed to perform updates"? could you give a short description? I am a fresh of blender/blenderproc.

I dont have a mac to test it, but it should be doable as described here: https://stackoverflow.com/a/59250494

Hi, I am facing the same situation. Even after allowing updates from my terminal as @cornerfarmer, I am getting ModuleNotFoundError: No module named 'h5py' error.

Did you find a solution?

Hey @alvaro-budria,

just running blenderproc pip install h5py should fix that. Alternatively you can also switch to the main github branch version. There this error should not occur anymore.
