Common Issues and Fixes

Common Issues and Fixes

  1. Do not install packages on the login nodes or inside a Jupyter Notebook. It has to be done in a terminal/shell:

$ interactive -t 30 -p htc $ module load mamba/latest

 

  1. Do not install any packages in the base environment.  If you see base in front of your username in the command line, please deactivate it:

(base) [example_user@sol-login01:~]$ (base) [example_user@sol-login01:~]$ source deactivate [example_user@sol-login01:~]$

 

  1. Improper use of the conda commands will inject some code into your ~/.bashrc file, which will cause problems. To remove these lines:

$ remove_conda_from_bashrc $ source ~/.bashrc

 

  1. Improper use of the pip install commands will create a hidden cache folder, which usually breaks Python-related functions. To check and remove such folders:

$ cd ~/.local/lib $ ls $ rm -rf python3* $ mamba clean --all

Please note that pip install can only be used after activating a mamba env:

$ module load mamba/latest $ source activate myENV $ pip install something

 

  1. How to install

    1. Pytorch, according to their official document:

$ interactive -t 60 -p htc $ module load cuda-12.6.1-gcc-12.1.0 $ module load mamba/latest $ mamba create -n myENV_pytorch -c conda-forge python=3.12 $ source activate myENV_pytorch $ pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu126 $ mamba install -c conda-forge other_packages ...

b. TensorFlow, according to their official document:

$ interactive -t 60 -p htc $ module load cuda-12.6.1-gcc-12.1.0 $ module load mamba/latest $ mamba create -n myENV_tensorflow -c conda-forge python=3.12 $ source activate myENV_tensorflow $ pip install tensorflow[and-cuda] $ mamba install -c conda-forge other_packages ...

 

  1. How to remove an env:

$ interactive -t 60 -p htc $ module load mamba/latest $ mamba remove -n ENV_NAME --all $ mamba clean --all
