Confused by module path for kivy.garden.graph

[David Aldrich]

Hi

I use kivy.garden.graph in my Kivy 3.4 app, which I develop on Windows:

from kivy.garden.graph import Plot, Graph, MeshLinePlot, MeshStemPlot, LinePlot

kivy.garden is installed in my user directory and I see

"C:\Users\<username>\.kivy\garden\garden.graph\__init__.py"

The app runs fine, but I run into problems generating documentation for the app using Sphinx. In the Sphinx conf.py file I specify:

sys.path.insert(0, "c:\\users\<username>\\.kivy\\garden\\garden.graph")

but when I run 'make html' to generate the documentation I see:

  File "C:\gui\main.py", line 56, in <module>

    import mygraph

  File "C:\gui\mygraph.py", line 23, in <module>

    from kivy.garden.graph import Plot, Graph, MeshLinePlot, MeshStemPlot, LinePlot

  File "<frozen importlib._bootstrap>", line 2237, in _find_and_load

  File "<frozen importlib._bootstrap>", line 2226, in _find_and_load_unlocked

  File "<frozen importlib._bootstrap>", line 1191, in _load_unlocked

  File "<frozen importlib._bootstrap>", line 1163, in _load_backward_compatible

KeyError: 'kivy.garden.graph'

Shorter versions of the .kivy path give similar errors e.g.:

sys.path.insert(0, "c:\\users\<username>\\.kivy\\garden")

My knowledge of Python modules and search paths is basic. Is the problem something to do with the fact that garden.graph just contains __init__.py and has no file such as graph.py?

Any help for how to fix this would be appreciated as it is breaking my documentation generation process.

Best regards

Really a Sphinx issue, perhaps.  The thing is that kivy.garden plays games with the import machinery in order to do its import.  It builds its own importer class and puts it on sys.meta_path.  I think the right thing to do is to not put anything in the Sphinx conf.py file.  kivy.garden already knows where to look.  The key thing with Sphinx is to make sure it calls "kivy" instead of "python".

Hi Bill,
Can you write how to make sure Sphinx is using "kivy" instead of "python"?
I'm also having issues with Sphinx in my app, exactly with kivy-garden modules.

Thanks a lot!

I don't know the answer to that, sorry.  You'll have to look at the Sphinx documentation.

You could look at http://stackoverflow.com/questions/8015225/how-to-force-sphinx-to-use-python-3-x-interpreter,

which seems to imply that "make html PYTHON=<path-to-kivy>" would work.  Or, if you can install Sphinx with pip, you could try "kivy -m pip install sphinx".  Lots of possibilities there.

I tried:

make html PYTHON="C:\Kivy-1.9.0-py3.4-win32-x64\Python34\python.exe"

but I still get the same error.

In case you're still having problems, I had the exact same problem with the same error but with kivy.garden.contextmenu, but I managed to fix it.

Here's what I did:

1. Add this to conf.py

sys.path.insert(0, os.path.abspath("path/to/libs/garden/garden.contextmenu"))

2. Change all my imports from

import kivy.garden.contextmenu

to

import context_menu

3. Also, to make sure my app still runs with these imports, had to add the line from step 1 to my app.
