Hm, that’s strange. Yes, would you mind sharing a notebook? I was just doing this last week

I could share an example notebook if it helps, but the only other thing I've done is run pip install rebound reboundx. Is there any workaround, or is the library incompatible with Google Colab?

Sorry, I think I fixed the access issue now.
Either way, I may have found a tentative solution. I had been using pip install rebound reboundx
at first, but when I switched to !pip install
I had no trouble importing reboundx. I'm still testing to see if any other issues arise, but at least the importing issue seems to have been solved.
I'm not sure what is going on but one issue could occur when trying to install both packages at once. I tend to have more luck first installing rebound, then reboundx. We're probably doing something wrong with the package requirements and shared libraries, but I'm not sure what...
I'm not totally sure what
pip install reboundx
is doing in colab when you don't include an exclamation point, but
!pip install reboundx
is definitely the right command to execute the command in the shell. I just ran it in a colab notebook (without installing rebound first) and it installed both no problem.
Closing for now, but feel free to reopen if there are further issues!
