Hi,
I'm having trouble documenting a class with the autoclass command. I specified where are my source files and I don't get import errors that tell me Sphinx is not finding my module. I think I'm getting this part right because when I go in the docs folder and I enter the command:
$ make html
the html files build well and I get what I want, which is this class documented.

When I build it with Read The Docs to have it hosted on https://picamera-gui.readthedocs.io/en/latest/code.html#picameragui-py, I don't get any error, but the class is not displayed.

In the admin settings of my Read The Docs project, I specified a requirements.txt file that I built with
$ pip freeze > requirements.txt

I also didn't check the Install your project inside a virtualenv using setup.py install box because I don't have a setup.py file in my folder and I don't know how I can install a virtual environment. When I check the box, I get this error in my Read The Docs builds

I think I'm missing something and if somebody knows rapidly what I'm doing wrong, it would be great.

If I forgot information that might help you finding my problem, here is my deposit:

Thank you,
Jérémy Talbot-Pâquet

PS: Sorry for the documentation in French

Thanks a lot! I didn't think there was any problems, because it was building. I already had my packages imported this way, but i forgot to add 'picamera'. Here in my conf.py.

It was probably building with make html because Python was able to locate the 'picamera' package, but Read The Docs didn't beacause I didn't specify it.

If anybody has their project building with the make html command, but not with Read The Docs, click on view raw in your Read The Docs build to ensure there is not something missing.
