When you upload a large CSV file to IDAS, there is a chance that the upload will crash your workspace. Even after closing out of IDAS and opening it back up, the browser may still be unresponsive.
It will often look as follows...
The steps listed below will walk you through how to resolve this issue.
1. Login to IDAS
Log onto IDAS at https://notebooks.hpc.uiowa.edu/ and select either research or your class depending on which you usually use to login.
2. Change the URL:
In order to save your current workspace. You'll need to change from the JupyterHub instance to the JupyterLab instance.
a. For research users:
- you'll change: https://notebooks.hpc.uiowa.edu/research-interactive/user/YOUR-HAWKID/tree
- to: https://notebooks.hpc.uiowa.edu/research-interactive/user/YOUR-HAWKID/lab
b. For class users:
you'll change: https://notebooks.hpc.uiowa.edu/YOUR-CLASS-NUMBER/user/YOUR-HAWKID/rstudio/tree
to: https://notebooks.hpc.uiowa.edu/YOUR-CLASS-NUMBER/user/YOUR-HAWKID/rstudio/lab
In general...
Go to the top of the screen to the URL that currently looks like: https://notebooks.hpc.uiowa.edu/research-interactive/user/HAWKID/lab
Then change "lab" to "tree" as follows...
This will take you out of your JupyterLab and into your JupyterHub which holds the same workspaces, just in different instances.
3. You'll need to save your open files. Start by going to the "Running" tab.
4. Once under the running tab, open a notebook you'd like to save.
5. Click on the "Save" icon.
6. Creating a clone workspace and deleting the crashed one:
Go to https://notebooks.hpc.uiowa.edu/research-interactive/user/HAWKID/lab?clone=foo
Make sure you did steps 3 through 5 This will override the old workspace.
You have now successfully restarted your workspace!
