No module named 'madpose.madpose'

[pablovela5620]

when running examples or trying to use this as a library in another application (by using this as a submodule) I get the following error

python examples/two_focal.py

Traceback (most recent call last):
  File "/home/pablo/0Dev/repos/madpose/examples/two_focal.py", line 7, in <module>
    import madpose
  File "/home/pablo/0Dev/repos/madpose/.pixi/envs/default/lib/python3.11/site-packages/madpose/__init__.py", line 1, in <module>
    from .madpose import *  # noqa
    ^^^^^^^^^^^^^^^^^^^^^^
ModuleNotFoundError: No module named 'madpose.madpose

if I use python -m examples.two_focal.py then things work but I'm trying to use this in another repo and get the same error. I don't know all that much about pybind. but it seems like maybe it has to do with how init.py is setup?

Hi, thanks for reporting this. This is indeed a bug where the non-editable installation does not include the .so file, and has been fixed by #5.

Let us know if you still encounter any problems, or kindly close this issue otherwise :)

sadly seems like I'm still encountering the same issue

it seems like now it won't even work how it did before

I'm wondering if it has to do with name clash and it might be better to call the cpp code _madpose? I tried most of yesterday to fix it but was unable to . So something like ._madpose *

I think you might need to delete the "build" and "madpose.egg-info" directories and try again. In my case, the revised version is working. However, yesterday I encountered the same problem.

OK, so I've found that when import madpose python first looks for the subfolder in current directory which does not contain the built .so library. If you do the import outside madpose root folder it should work fine.

#7 changes the output directory of the .so file and adds a post-build action in CMake to make the import works in both cases. This somehow breaks editable install (pip install -e) but should allow to use madpose with normal installation. I am no expert on installation with pip so if anyone has an idea of how to better fix this in a cleaner way welcome to make a PR!

Looks like its working now! Thank you for the help
