Hello there,
I'm trying to install a Python package from GitHub using "reticulate" in RStudio. However, I encountered an error. Could you please assist me in resolving this issue?

Thank you,

From the documentation, {reticulate} can only install from PyPI and Conda, not from Github.

So you'd probably want to create a Python environment (with conda or venv) from reticulate, then run python's pip command to do the installation without using reticulate. Some people seem to have managed here and there.

Btw. I would also add a reticulate tag to questions about reticulate, to make it more likely that the right people see it.
