Github workflow does not render API documentation

[sanghyukmoon]

When I build and deploy the jupyter book manually by

$ PYTHONPATH=./ jupyter-book build docs/
$ ghp-import -n -p -f docs/_build/html

then API documentation is rendered without any problem. For example, see https://sanghyukmoon.github.io/grid_dendro/dendrogram.html#

However, when github action does that for me, the API documentation is not rendered. For example, see the jupyter book in Chang-Goo's fork https://changgoo.github.io/grid_dendro/dendrogram.html

@changgoo Do you have an easy solution for this?

from the workflow log, I see these lines

WARNING: autodoc: failed to import module 'boundary' from module 'grid_dendro'; the following exception was raised:
No module named 'numpy'
WARNING: autodoc: failed to import class 'dendrogram.Dendrogram' from module 'grid_dendro'; the following exception was raised:
No module named 'numpy'
WARNING: autodoc: failed to import module 'energy' from module 'grid_dendro'; the following exception was raised:
No module named 'numpy'

This means it doesn't have numpy on the runner. The solution is to add numpy (and other dependencies if exists) in the requirements.txt.

Thank you so much! Now it is working fine.
