Hello, I can´t do some operations in the GPA moduel, when I try to paste the code in the phyton window, I got this message: UserWarning: Could not import the lzma module. Your installed Python is incomplete. Attempting to use lzma compression will result in a RuntimeError.

What can i do?

Thanks for letting us know. This is not an error. When a package imports “pandas” package then pandas logs this warning. It is highly unlikely that you will need lzma compression, but if yes, then you’ll get an error message, so you can safely ignore the warning.

Anyway, this issue is tracked [here](https://github.com/Slicer/Slicer/issues/4920), but unless it blocks someone from doing something, its priority will remain low.

Hi Sara! Actually I was able to run it…I think the problem is my computer memory. Thank you!
