JupyterLab

Description

From the JupyterLab website: JupyterLab is a web-based interactive development environment for Jupyter notebooks, code, and data. JupyterLab is flexible: configure and arrange the user interface to support a wide range of workflows in data science, scientific computing, and machine learning. JupyterLab is extensible and modular: write plugins that add new components and integrate with existing ones.

JupyterNotebook is one of the tools available for use in the JupyterLab suite.

PLEASE NOTE: Do not run JupyterLab on a login node, as it can be resource intensive. Instead, please ensure that you only run it inside of an SRUN Interactive session.

Using JupyterLab on CIRCE/SC via X2Go

Installing JupyterLab

To install JupyterLab, you'll first need to log-in to CIRCE/SC via X2Go, open a terminal window, and install Miniconda3 using the directions below:

Instructions on installing Miniconda3

```
[user@itn0 ~]$ cd $HOME
```

[user@itn0 ~]$ wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh

[user@itn0 ~]$ chmod +x Miniconda3-latest-Linux-x86_64.sh

```
[user@itn0 ~]$ ./Miniconda3-latest-Linux-x86_64.sh
```
- answer "yes" to adding Miniconda3 install location to PATH in your ~/.bashrc
log-out of CIRCE/SC, then log back in
```
[user@itn0 ~]$ conda activate base
```
```
[user@itn0 ~]$ which conda pip
```
- make sure it returns with both lines below:
  - ~/miniconda3/bin/conda
  - ~/miniconda3/bin/pip

[user@itn0 ~]$ pip install --upgrade pip

```
[user@itn0 ~]$ conda update --all -y
```

[user@itn0 ~]$ conda install -y anaconda

Once Miniconda3 is installed, you can proceed with installing JupyterLab.

Instructions on installing JupyterLab via Miniconda3

To create a dedicated JupyterLab Miniconda virtual environment, you can do so by running the commands below:

```
[user@itn0 ~]$ cd $HOME
```
```
[user@itn0 ~]$ conda activate base
```

(base) [user@itn0 ~]$ conda create --name jupyter -c conda-forge jupyterlab

```
(base) [user@itn0 ~]$ conda deactivate
```

Running JupyterLab inside of an SRUN Interactive Session

PLEASE NOTE: When running inside of an SRUN interactive session, ensure that your "--time" request is sufficient to complete your processing. If your interactive session runs out of time, your JupyterLab processes will be terminated, and any unsaved work will be lost!

Each time you wish to run JupyterLab, you can do so by running the commands below:

Connect to CIRCE/SC via X2Go
Open a terminal window (inside of X2Go) to run commands 3-8 below

Export your DISPLAY variable

[user@itn0 ~]$ export DISPLAY=$(hostname)$DISPLAY

Request a 1-core, 1GB of RAM SRUN Interactive Session for 1 hour:

[user@itn0 ~]$ srun --time=01:00:00 --ntasks=1 --mem-per-cpu=1G --pty /bin/bash

Once the SRUN Interactive Session has been dispatched, load your JupyterLab conda environment:
- ```
[user@mdc-1057-29-41 ~]$ conda activate jupyter
```

Load the module for Firefox and start Firefox in the background:

(jupyter) [user@mdc-1057-29-41 ~]$ module add apps/firefox

(jupyter) [user@mdc-1057-29-41 ~]$ firefox &

Start JupyterLab:

(jupyter) [user@mdc-1057-29-41 ~]$ jupyter lab

Copy the "localhost:8888" URL from the terminal into Firefox to load the Jupyter Lab GUI

Terminating JupyterLab

When you are finished using JupyterLab, you can terminate the processes using the steps below:

Close the Firefox window
In the terminal window that you ran "jupyter lab" in (in step 7 of Running JupyterLab inside of an SRUN Interactive Session), press CTRL-C and enter "y" to confirm terminating the JupyterLab server process

Deactivate your JupyterLab virtual environment

(jupyter) [user@mdc-1057-29-41 ~]$ conda deactivate

Type "exit" to exit your SRUN interactive session
