Can not run codes on jupyterlab for all practice labs

when I open the lab, the jupyterLab does not connect to kernel and run code blocks. what should I do ?
I have this problem for 3 courses of Machine Learning !!!


Are you running the code on your local computer?


Did you try the classic Jupyter Notebook instead of JupyterLab? If not,
Here are the commands:

pip install notebook
jupyter notebook

I installed it .
But, I try the code on coursera online jupyterlab and again it does not work!!

What’s the error?

you are suppose to do these assignments on Coursera work environment. Can I know reason behind you doing on you local computer??

Now, everything is OK.
I’d like to practice more on my lap top.

I fixed it. Tnx.
