Jupyter notebook not opening in VS Code

Question

While setting up my new system, I am trying to run my notebook file on VS Code but as soon as I open VS Code it give me this error

Failed to detect Jupyter Notebook. Please use 'Select Jupyter Notebook' command

in the output:

I have installed all the plugins which were necessary, ran various commands, I also updated the notebook. conda install notebook

I am using: anaconda 3 vs code 1.26.1 windows 10 I cant start new notebooks or use an existing one either. Please help, and let me know if any more information is required.

Answer 1

1. Check the required extensions installed in vscode.

2. install jupyter and ipython packages in your python venv using pip:

    pip install jupyter pip install ipython

3. If its still not working try to change the python kernal in the top right corner of ipynb notebook.

Answer 2

This is due to running jupyter without first activating the environment for Python 3.7. This was fixed in the 2018.12.0 release of the extension.

Answer 3

When it fails with this response you can uninstall conda and jupyter and install python from VS Code and then update. Don't necessarily install conda and jupyter .
