Mujoco, dm_control, EGL Errors

[shneorkairois]

Hello, whatever the version of dm_control I set I keep getting this errors.

AttributeError: 'NoneType' object has no attribute 'eglQueryString' 

I am desperate to know if someone has found a fix.

Excuse me, I also encountered this problem. Could you tell me if you have solved it?

[shneorkairois]

I haven't, I would however advise you to follow the following steps. My understanding has been that, I had a deep peer dependency issue. I moved to python 3.9, and went from Ubuntu to Debian since, then I haven't encountered the problem. #136

I solved the issue with the following Dockerfile:

# Use the official image as a parent image
FROM tensorflow/tensorflow:2.0.0-gpu-py3

ENV MJLIB_PATH=/tf/mujoco200_linux/bin/libmujoco200.so
ENV MJKEY_PATH=/tf/mujoco200_linux/bin/mjkey.txt
ENV MUJOCO_GL=osmesa
ENV LD_LIBRARY_PATH=/tf/mujoco200_linux/bin/
ENV PYOPENGL_PLATFORM=osmesa

# i need this for ffmpeg
ENV PATH="/tf/.local/bin/:${PATH}"

RUN apt-cache search mesa
RUN apt-get update && apt-get install -y libgl1-mesa-glx libosmesa6

# Run the command inside your image filesystem
RUN pip install --upgrade pip && \
        pip install gym && \
        pip install gym[atari] && \
        pip install PyOpenGL==3.1.0 && \
        pip install dm_control && \
        pip install tqdm && \
        pip install np_utils && \
        pip install opencv-python

Thank you very much! I will have a try.

Thank you very much! I will have a try.

Excuse me, have you solved it? I have tried the solution but haven't solved the problem.
