Compatible with Python3?

[wbensvage]

I was using Python3 and tried to install OpenDR via pip. But I failed and found opendr now seems only compatible with Python 2? So can I know is there any plan to move opendr forward to Python 3? And is there any way I can overcome this currently?

anyone could reply this?

There is an updated version of opendr here but this one is not official though.

I tried installing opendr on python 3 on anaconda using both pip and conda, but failed. Can anyone help me on this? I also tried finding .whl file for opendr, but couldn't.

@SelvamArul Do you know how we can install that? Thanks in advance

[SelvamArul]

@AnirudhPuligandla Could you please elaborate on your question? Sorry, I didn't get what you mean by install. It is just a python package. Noting to install there.

[AnirudhPuligandla]

@SelvamArul Sorry for the vague question! Actually I am testing some code that uses opendr to display images and a 3D mesh. So, i have this modern opendr package in my PYTHONPATH with the other requirements installed. But, i am not sure if this package can readily replace opendr (in terms of fucntions to open a window, display etc.) as i still encounter the same error "no module named opendr". I am using python3.5

I hope that is clear.

Thanks

@AnirudhPuligandla What is the exact path you have in your PYTHONPATH? I will share my setting as an example. Maybe you can spot any differences to yours.
I cloned the updated opendr from here to ~/workspace and then added ~/workspace/opendr to my PYTHONPATH.
Let's check with python interpreter.

import sys
for i in sys.path:
    print (i)
...
/home/arul/workspace/opendr
...
# opendr is in sys.path
import opendr
print (opendr)
<module 'opendr' from '/home/arul/workspace/opendr/opendr/__init__.py'>
print (chumpy)
<module 'chumpy' from '/home/arul/workspace/opendr/chumpy/__init__.py'>

Hope this helps.

@SelvamArul To clarify, have you gotten it working in python3? Also, did you manage to do everything with PYTHONPATH? I'm not sure how python3 absolute imports works under the hood, nor how pip and conda do

[SelvamArul]

ya, this fork is python3 compatible. I have forked it further to make to compatible with latest versions of NumPy and Scipy, and few other bug fixes related to wrong dimension specification while reading out the rendered images from OpenGL. You can find my fork here.

Regrading the PYTHONPATH, I didn't get your question. Could you please describe your issue in detail?

I used your fork and met this error:
AttributeError: 'ColoredRenderer' object has no attribute 'vbo_verts_face'
Could you help me find out what's wrong?

@willie1997 have you managed to solve this issue?

I was finally able to install OpenDR through PIP on Python 3.7 in a conda environment. What worked like magic for me was installing libosmesa6-dev:

conda create -n smpl python=3.7
conda activate smpl
conda install numpy
conda install chumpy
conda install -c conda-forge opencv

sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev
sudo apt-get install libosmesa6-dev
pip install opendr

Hope this helps!

[erezposner]

@salmedina are you working under linux/windows?

[salmedina]

@erezposner This was on Ubuntu 18.04.3 LTS

[WilliamWang1994]

Maybe you can try the modern version from polmorenoc.
it seem like work on windows.

[yohanshin]

@salmedina Following your description, it perfectly works on my ubuntu-18.04 LTS too! Just instead, since conda doesn't have their chumpy cloud, try pip install chumpy

[yutao007]

conda install chumpy ------wrong

[bmquynhlinh]

This solution works for virtual env python3.10 too
sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev sudo apt-get install libosmesa6-dev pip install opendr

I was finally able to install OpenDR after upgrade Cpython
pip install --upgrade Cython
