My jupyter lab is not showing any output

JupyterLab
1

I recently bought a new laptop and decided to install Jupyter Lab locally. I first installed Python 3.14 and set up the environment variables. Then I installed Jupyter Lab locally using pip:

pip install jupyterlab ipykernel

After that, I registered my Python kernel with Jupyter:

python -m ipykernel install --user --name python314 --display-name "Python 3.14"

I opened Jupyter Lab in Chrome. The kernel takes some time to connect, and when I try to run even basic code, it does not show any output. A star (*) appears to the left of the code cell, and the status at the bottom shows “Idle.”

So what is the problem here?

Can you try downgrading ipykernel to 6.x?

This looks the same as Notebook for Python 3.14.0 won't connect to kernel

@mdtowfiq30 are you using Windows, Mac or Linux?
