Jupyter Lab, Desktop Environments, and Text Editors

Description:

Earlier in the workshop you launched a VICE image with RStudio. Follow the same process again using our Jupyter Lab Geospatial container instead.

We have integrated Project Jupyter’s Data Science Jupyter Lab images with geospatial packages.

We have also integrated an all-in-one container which supports a desktop environment, Jupyter, VS Code (or your favorite text editors), and even RStudio. This container represents a ‘Workspace’ where you can do almost all of your daily data science tasks.

Starting the VICE app

1. Log into the Discovery Environment: https://de.cyverse.org

2. Click one of our quick launch buttons:

  • Jupyter Lab Geospatial: jupyterlab-geospatial

  • Workspace: workspace-geospatial-latest

Or, search using the apps_button ‘Apps’ search bar.

query “jupyter lab geospatial” or “workspace geospatial” and see what comes up.

Or, click the App button and a new window should open.

Under “My Apps” section click on the “My Communities” section and “NEON” Group should appear

3. In the App Window you have a few options.

i. Analysis Name - you can change the name of the analysis if you like, the default name is typically <the-app-name>_analysis1

Your analysis will run, and when it completes, it will write any data that you have in the WORKING DIRECTORY of the container back to the Data Store in your Analyses folder, e.g. /iplant/home/<username>/analyses/<the-app-name>_analysis1-<DATE-TIME-of-job-starting>

ii. The second section is Input Data and has options for adding (1) a folder, (2) a single file, or (3) multiple files.

For our use case today, we’re going to add a folder from the data store.

add_data_window2

Add the path: /iplant/home/shared/NEON_workshop/

add_data_window1

iii. The third section is Resource Requirements, again you can leave the default settings.

You can set the Minimum CPU to the minimum number of cores your app requires. If you do not select anything, the app will still be able to use multiple cores on the shared node on which it is deployed.

You can set the Minimum RAM to the minimum number of GB of RAM you think your app requires.

You can set the Minimum Disk Space to the minimum amount of scratch space you think your data will need.

iv. After you’ve set the analysis name, input data, and resource requirements, click Launch Analysis

Watch closely, you’ll see a notification at the top of your screen and in the Bell icon in the upper right.

4. Open the analyses_button icon labeled “Analyses” to view your running analysis.

Look for your App Name. See the square icon with an arrow pointed up to the right? Click on that icon and a new tab will open.

analyses_window

Alternately, click the Bell icon in the upper right to see your notifications, you should see ‘Access your running analysis here.’ as an option. Click on that link and a new tab will open.

5. Having clicked on either of the hyperlinked icons in Step 4 should result in a new tab opening in your browser.

Your Discovery Environment Browser tab should still be open.

The new URL for the instance has changed from https://de.cyverse.org/de/ to something like https://af7664685.cyverse.run/.

This is a new instance is running a Virtual Machine for you on CyVerse cloud.

You can now begin working in your running instance.

Description of output and results

You should now be ready to run the NEON Python API tutorial

Note, there are pre-completed .ipynb notebooks in the /tutorials folder which you added to the Instance when it was created. These should be in the working directory under the /NEON_workshop directory. You can use these for guidance, particularly if you fall behind.
