#### My directories are not full, but my Open OnDemand JupyterLab Session is still not starting. What else should I try?
If the inode and storage quotas of the `$HOME` and `$WORK` directories on Swan are not exceeded, and your Open OnDemand JupyterLab Session is still not starting, there are two additional things you can check:
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 $HOME/.bashrc` to apply the changes.
Whether you have renamed the `$HOME/.local` directory and/or modified the file `$HOME/.bashrc`, please cancel and restart your JupyterLab Session.
#### Why my Open OnDemand RStudio Session is crashing?
There are two main reasons why this may be happening:
1) The requested RAM is not enough for the analyses you are performing. In this case, please terminate your running Session and start a new one requesting more RAM.
