Cannot Connect to Kernel issue #5396

Open user23ayush opened 4 years ago

user23ayush commented 4 years ago

Screenshot (48) As i found the solution is to downgrade the tornado pip to 5.1.1 . Either using pip install tornado==5.1.1 command or the screen shot method . But I cannot access the Mark to install the version as shown in screenshot. when I run the command

C:\Users\AYUSH>pip install tornado==5.1.1 Requirement already satisfied: tornado==5.1.1 in e:\anaconda3\lib\site-packages (5.1.1)

but still it shows cannot connect to kernel in Jupyter notebook. Please Help me i am stuck at this

What is produced on the notebook server console when attempting to start a kernel?

What is produced on the notebook server console when attempting to start a kernel?

Screenshot (50) I think this is the error you are asking

This is what I get when I launch Jupyter notebook C:\Users\AYUSH>jupyter notebook [I 20:28:02.669 NotebookApp] The port 8888 is already in use, trying another port.

Hmm - looks like some critical status log message was about to be produced.

First, I suspect you have a couple notebook servers already running (on ports 8888 and 8889) that we should probably stop. Control-C (twice) out of this instance, then:

jupyter notebook stop 8888
jupyter notebook stop 8889

Once back to a clean state, please to the following:

Thanks.

Thank you for you efforts sir but the problem still persists

Hmm - looks like there's an issue during the initialization of the python kernel. I'm not sure downgrading tornado is necessary (your findings may have been associated with an older issue). I would recommend updating tornado and ensure you're running the latest versions of ipython and ipykernel.

If that doesn't result in successful start-up, and no one else here has other ideas, you might try opening an issue (with this information) in https://github.com/ipython/ipython.
