DOC, BUG: API reference fails to build on remote with `sphinx` about kda HOT 2 CLOSED

This thread on stackoverflow is very similar but their suggested solution regarding the .readthedocs.yaml wouldn't fix our issue (we already do it this way).

from kda.

With some testing, it seems the issue is the kda requirements were not included in the docs/requirements.txt file. This is not clear from the error messages given in the terminal output, but it seems the RTD documentation does specify the Python dependencies should be in the requirements.txt for the docs:

Create a requirements.txt file at the root of your repository. This file should contain every name of the parts needed to build the documentation (Python modules, extensions, etc).

Like I said, it is not clear from the warning messages that the inability to import numpy is causing the failure. I guess they expect you to make an educated guess that the ModuleNotFoundError is invalid?
