Hello! I have an ImportError when I try to import envlogger. I get this error on my computer and in GoogleColab notebook. How can I resolve it?

Hello @artfawl, since compiling GMP from source via Blaze isn't supported, we rely on it being installed on the target system. Please see here: https://github.com/google-deepmind/envlogger?tab=readme-ov-file#compiling-from-source

In Colab, you'll still need GMP in place, and you can easily install it with: !apt install libgmp-dev.

I was able to reproduce your error without installing GMP, and after installing it and !pip install envlogger, I'm able to do import envlogger with no problems.

Let me know if this works for you, and if it does, please close the issue. Thanks!
