ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
atom 0.4.0 requires numpy==1.26.4, but you have numpy 2.2.6 which is incompatible.
This is an issue for me, because I'm stuck on numpy 1.x for other reasons. I think that the opencv numpy constraint could be relaxed, however. From the numpy docs:
When you build wheels for your package using a NumPy 2.x version at build time, those will work with NumPy 1.xx.

Is there some other reason that I'm not aware for the incompatibility? Otherwise, I can open a PR for this.
