1) If a custom conda environment is not used, when installing packages with `pip` locally, these libraries are installed in `$HOME/.local`. When using other modules or applications that are based on Python/conda (e.g., Open OnDemand JupyterLab), these local installs can cause conflicts and errors. In this case, please rename the `$HOME/.local` directory (e.g., `mv $HOME/.local $HOME/.local_old`).
2) Please make sure that you don't set variables such as `PYTHONPATH` in your `$HOME/.bashrc` file. If you have this variable set in the `$HOME/.bashrc` file, please comment out that line and run `source $HOME/.bashrc` to apply the changes.
