Easy solution
It sounds like you're using a 32-bit version of Python (I also assume you're running on Windows). From the numpy.memmap docs:
Memory-mapped files cannot be larger than 2GB on 32-bit systems.
So the simple solution to your problem is to just upgrade your Python install to 64-bit.

You say that you didn't commit it. Unfortunately git only saves commits and not undone work. So, as sorry as I am, there is no way to use git to get your work back.
But you could try to restore the deleted files.

I am so confused and I think I've lost hours of work.
I was editing a file in Git earlier, and I saved it, but did not commit. I did do a few other file changes, and commited and pushed them.
