내가 안까먹을라고 적어놓는 우분투 쥬피터랩 설정 팁들

Ubuntu_JupyterLab_Tips_for_me.md

1. Install jupyterlab on Ubuntu without conda.

# sudo apt update  # if needed
# sudo apt install python3-pip python3-dev  # if needed
pip3 install jupyterlab

2. Generate a Jupyter configuration file and modify.

   # Create a configuration file at `~/.jupyter/jupyter_lab_config.py`.
   jupyter lab --generate-config
   
   # Open the configuration file in a text editor.
   vi ~/.jupyter/jupyter_lab_config.py

   • ex1) Change the port.

     # find the line in `~/.jupyter/jupyter_lab_config.py`
     c.ServerApp.port = 8888  # uncomment and change to desired port

     Or, alternatively, set the port temporarily.

     jupyter lab --port=8888

   • ex2) Set the password.

     from jupyter_server.auth import passwd
     passwd(algorithm='sha1')  # enter desired password to input.

     # find the line in `~/.jupyter/jupyter_lab_config.py`
     c.ServerApp.password = 'sha1:7ddaddc0d166:b2f60bec76c286c2a68b2d703cf2a24db2a5d3f5'  # example when password is set to '1234'

     Or, alternatively, set the password temporarily.

     jupyter lab --NotebookApp.token='1234'  # example when password is set to '1234'

   • ex3) Set the root directory.

     # find the line in `~/.jupyter/jupyter_lab_config.py`
     c.ServerApp.root_dir = '/path/to/your/directory'  # uncomment and change to desired directory

     Or, alternatively, set the root directory temporarily.

     jupyter lab --notebook-dir=/path/to/your/directory
     # or
     jupyter lab --LabApp.root_dir=/path/to/your/directory

3. Use a virtual environment as a jupyter kernel.

   • Register kernel.

     1. Activate the virtual environment.

        source /path/to/venv/bin/activate

     2. Install ipykernel in the virtual environment.

        pip install ipykernel

     3. Add the virtual environment as a kernel.

        # Run the code while virtual environment is still active.
        python -m ipykernel install --user --name name_of_kernel --display-name "Kernel Name"

   • Unregister kernel.

     1. View the list of all registered jupyter kernels.

        jupyter kernelspec list

     2. Remove the virtual environment from jupyter.

        jupyter kernelspec uninstall name_of_kernel
