Requirements

• Install prerelease jupyter extension into http://insiders.vscode.dev
• Have a python environment that you can run jupyter from. (https://jupyter.org/install)
• install pandas into that environment as well
• Be familiar with jupyter notebooks

Pre test steps

1. Go to a command prompt
2. Activate the python environment with jupyter in it
3. Run jupyter with the following command line : jupyter notebook --no-browser --NotebookApp.allow_origin=*
4. Note the URL it generates for connecting
5. Start insiders.vscode.dev
6. Make sure Jupyter prerelease extension is installed
7. Bring up command palette
8. Pick ‘Jupyter: Specify jupyter server for connections’
9. Pick ‘Existing’
10. Enter the URL from step 4

Test kernel completions

1. Open a new notebook
2. Pick the ‘Python 3’ kernel
3. Add some code
4. Run a cell
5. Create a new cell with ‘import pandas as pd’
6. On the next line, type ‘pd.’
7. Verify that you get completions for pandas
8. Try loading a CSV file in pandas (or create a dataframe with columns)
9. Verify that you can get ‘column’ completions. For example, if you create a dataframe named df, typing df. should list the columsn of the dataframe.

We finally figured it out. For some reason on Isidor’s machine, it needs this jupyter notebook --no-browser --NotebookApp.allow_origin='*'. Quotes around the * in the allow_origin.
