Udacity Deep Reinforcement Learning - p2 & deeprl env setup

πŸ‘‰ check the drlnd_py310 env setup notes
πŸ‘‰ check the p1 env setup notes
πŸ‘‰ course curriculum
πŸ‘‰ Colab notebooks


Window 11, VSCode, Minicoda, Powershell

πŸ‘‰ copy from the env where cuda and pytorch have been installed
🟒 conda create --name drlnd_p2 --clone drlnd (Python 3.6)

(base) PS D:\github\udacity-deep-reinforcement-learning\python> conda create --name drlnd_p2 --clone drlnd
Source:      D:\Users\*\miniconda3\envs\drlnd
Destination: D:\Users\*\miniconda3\envs\drlnd_p2
Packages: 159
Files: 13970
  • or check how to install cuda + pytorch in windows 11
    conda install cuda --channel "nvidia/label/cuda-12.1.0"
  • or go to https://pytorch.org/, and select the right version to install
    ❌ pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
    🟒 conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
pip install torchmeta
conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidi

🟒 Follow these steps to install mujoco-py on Windows

🟒 Powershell $env:PATH += ";C:\Users\*\.mujoco\mjpro150\bin"
 Powershell $env:path -split ";" to display path variables

🟒 download mujoco-py-1.50.1.68.tar.gz from https://pypi.org/project/mujoco-py/1.50.1.68/#files

pip install "cython<3"  
pip install mujoco-py-1.50.1.68.tar.gz  
python D:\github\udacity-deep-reinforcement-learning\python\mujoco-py\examples\body_interaction.py  
  • you might need this pip install lockfile and some other packages. install them according to the error messages.
  • a worse case is that your python version is too high (maybe >=3.9?), you might need to install mujoco_py manually.
  • now you should be able to see this.

πŸ‘‰ install gym atari and lincense

git clone https://github.com/openai/baselines.git
cd baselines
pip install -e .
  • for python 3.11, you can pip install opencv-python.
    and i Successfully installed opencv-python-4.9.0.80.

πŸ‘‰ intall the rest packages for the deeprl folder.
pip install -r .\deeprl_files\requirements.txt

  • for python 3.11, losen the version requirement scikit-image.
    I got scikit-image-0.22.0 installed.

πŸ‘‰ test the env setup

TypeError: Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
