Jupyter-lab did not open Jupyter notebook

[Ewaoluwa1]

I wanted to open jupyter-lab after activating my imcsegpipe environment, then I got the following:

What should I do?

Hi @Ewaoluwa1

Thanks for your question. Are you running the command locally or remotely? If locally, then you can paste the URLs at the bottom into a web browser?

[Ewaoluwa1]

@Milad4849 I am running the command remotely. I pasted the URL you mentioned on the web browser but "..can reach the page"

[jwindhager]

Just briefly: When running Jupyter Lab remotely, you will need to either set up SSH tunneling, or configure Jupyter Lab to allow remote access (and then replace the "localhost" in the URL with your server's IP/address). Probably easier to do the former. Depending on your operating system, @Milad4849 can probably give better hands-on instructions :innocent:

[Milad4849]

@Ewaoluwa1 I suggest to contact your system administrators regarding the establishing of a ssh connection, as the precise instructions can vary depending on the set-up. Once that is done you can start jupyterlab with the following command jupyter lab --no-browser --ip <ip of your instance>. This would give you a URL that you can paste into the browser on your local machine to access the jupyter session.

So I changed to running the command locally (I was working remotely initially), and the command worked. Thank you all for your reply
