python - RTD: Read the docs only import links and not the contents in it -

i new read docs. have documentation folder docs in github repo created using sphinx in local machine. tried link docs readthedocs.

from settings of repo added read docs service.

from read docs website imported project.

but, documentation in read docs shows front page of index.html file. when click links empty. however, in local machine links text in it.

my github repo this: github repo

my readthedocs link : readthedocs docs

file structure

• docs
  • html
  • rst
    ** conf.py
  • source
  • makefile
• src

the main page of index.html

in machine when click first link has contents

in readthedocs website when click first link emptey

note whole repo same in both github website , local machine.
files in computer uploaded in github, still readthedocs can not find documentation.

question: how can show contents of links in readthedocs ?

what doing wrong?
there way fix problem or rtd shows front page?

simple test:
can download repo (5mb) , run index.html shows contents inside a0_interpolate_flux link, if click same link in readthedocs given above not show docstring contents.

update
have googled lot , tried read docs website, no avail. wonder how same html page opens differently in local machine , readthedocs webhost?

you need tell rtd install package. see rtd faq my project isn’t building autodoc.

if @ rtd build history, , expand third bar, see import errors.

to fix it:

1. configure rtd admin use virtual environment , install package, using requirements.txt file.
2. create requirements.txt file , push repo, specifying project's requirements, included.
