My jupyter show me no output

[mohamed_mohamed_saad]

I was working on my second project and every thing was fine, suddenly and without any reason when I run each cell alone it gives me no response at all . although the previous cells had already gave me outputs and when I ran it again the output disappeared.

no output , no plot , nothing at all.

any ideas?

There’s a good chance the kernel or server has stopped. You can try saving your notebook and then reloading the page to get a fresh connection.
