Practice 9:

Fixes on Jupyterhub

  • Out of memory -> use the conda environment from project home folder (Execute these lines once - not every exercise)

conda activate /projects/p_lv_ml_robotics/envs/ml4robotics

jupyter kernelspec remove ml4robotics

python -m ipykernel install --user --name ml4robotics

  • Packages from conda env are not found (e.g., gymnasium not found) -> 1) check if you have selected the correct kernel 2) remove your own conda env and reinstall the kernel from project home

conda env remove -n ml4robotics

conda activate /projects/p_lv_ml_robotics/envs/ml4robotics

python -m ipykernel install --user --name ml4robotics

  • OpenGL on Barnard seems to be broken -> Use Alpha, Romeo, Colab, or local
