Build failed: code error for my code in Readthedocs

问题

I am trying to link my Sphinx documentation with Readthedocs. I can build the documentation locally in my computer but when I try to have Readthedocs automatically generate the documentation I get the following error:

Configuration error:
There is a programmable error in your configuration file:

Traceback (most recent call last):
  File "/home/docs/checkouts/readthedocs.org/user_builds/helstrom-quantum-centroid-classifier/envs/latest/lib/python3.7/site-packages/sphinx/config.py", line 368, in eval_config_file
    execfile_(filename, namespace)

    import sphinx_gallery
ModuleNotFoundError: No module named 'sphinx_gallery'

I have imported sphinx_gallery in my conf.py file as well as added the extension 'sphinx_gallery.gen_gallery'. My conf.py file is located here: https://github.com/leockl/helstrom-quantum-centroid-classifier/blob/master/docs/conf.py

And my Github project is located here: https://github.com/leockl/helstrom-quantum-centroid-classifier

Where have I gone wrong?
