Just using Jupyter for the first time. I have noticed that the the abbreviation ‘In’ (for input) is missing to the left of the code line (please see picture). I am only getting the number in the brackets and not the ‘In’
I would in particular suggest reading the second half of my answer here, which was the last ‘See Also’ link I posted above. The references therein go into more detail on how things have changed in the ecosystem.
If you are new to this, I would suggest getting used to it as this is the direction of current and future development of the Jupyter interface.
Alternatively, you can opt to use NbClassic:
Please don’t crosspost without linking the posts at different locations. Without that acknowledgement you can often cause multiple people to say the same things in different locations and create information silos as others don’t realize there is a valuable solution at the other location.
Did you check what version you are using vs. the coverage I referenced towards the bottom of my answer here?
If you are looking for other ways to look at what you should see for various versions without touching your system, you can go to here and click into the READMEs in the various gists there and click the ‘launch binder’ badges to control what interface opens in a temporary session on a remote computer.
There is a route to NbClassic there too, which is the older style with the In and Out next to the brackets. To see that one, go there click on the ‘launch binder’ badge and when the session comes up edit the URL to remove the /tree and change it to nbclassic and then hit enter to switch to that URL. (There’s easier ways to get there but I was trying to spell out the way that will work with what is there for now. That gist is more of a outline of what is available and so it isn’t set up as user friendly as it could be. I referenced it because I was sending you there for others.) You should then get the older style. However, as a new user I would caution you to adopt the new, current version.
