Add an option to define a constraints.txt file

[almfisch]

Custom nodes often have something like numpy in requirements.txt.
This means that the latest version is installed during installation, e.g., numpy 2.3. This causes problems because numba only runs with numpy 2.1. This could be prevented by creating a contraints.txt file and writing numpy==2.1.0 in it, for example, so that custom nodes do not install any other version.

My idea would be to add a field in the manager where you can specify the path to a contraints.txt file. If the field is not empty and the constraints.txt file is found, the manager should take this into account when restarting.

Something like
if constraints_path:
([‘install’, ‘-r’, requirements_path] ‘--constraint’, constraints_path)
else:
([‘install’, ‘-r’, requirements_path])

Or is it the same like this:
Configurable pip auto fix: <USER_DIRECTORY>/default/ComfyUI-Manager/pip_auto_fix.list
