I am running pyspark scripts in jupyter notebook but the kernel is not starting. upon selecting pyspark from the dropdown the kernel loads and remains busy for some time and then shows "no kernel".
Can someone help me?
Note: upon running "$Jupyter kernelspec list" i can see pyspark kernel in the list.
The issue was resolved only by re configuring the Jupyter notebook.

I have added a new kernel to my jupyter notebook. It works totally fine using Jupyter in the browser. However if I try to open my notebook in VSCode (and change the kernel) it doesn't show up --> the drop-down menu doesn't show my kernel.
Is there anything I can do to resolve this issue.
Thanks in advance!
I am trying to run matlab code from Jupyter notebooks.
I am following the link below for guidance:
https://www.youtube.com/watch?v=WufMGW5Bv4g
Now I have installed matlab_kernel. And I see that it is installed on the machine when i run a pip list.
When I open Jupyter notebook, and click on the New notebook dropdown, I do not see the MATLAB option.
Also, at point 3:22, the instructor installs python from Program Files/Matlab.
However, I do not see the MATLAB folder in my Program Files.
What am I missing here. Any guidnce would be very helpful.
I prefer using the ipython enhanced REPL over the python and so am specifying as such in the pyspark command line:
Result: jupyter notebook launched (surprising):
PYSPARK_DRIVER_PYTHON=ipython MASTER="local[*]" $SPARK_HOME/bin/pyspark
This approach was working for several years - but at the present it is causing jupyter notebook to be launched.
That result would make sense if the explicit command notebook were also present:
Result: jupyter notebook launched (expected):
PYSPARK_DRIVER_PYTHON=ipython notebook MASTER="local[*]" $SPARK_HOME/bin/pyspark
Given that the notebook is not specified then why is the notebook launched instead of the REPL ?
Note: when using ipython alone on the command line via
Result: ipython REPL launched (expected):
ipython
the REPL is launched (and not the jupyter notebook).
you might have set PYSPARK_DRIVER_PYTHON_OPTS variable to "notebook". this will cause to open jupyter notebook
I am using jupyter notebook for my python work. I have a large dataset .mat file which I am trying to load using scipy package using loadMat function. When I am trying to load my data file, my jupyter kernel dies and restart without any error in the console.
python console works fine and it loads data properly.
I am using ubuntu machine.
Can someone please let me know what is the issue with the jupyter notebook
I have accidentally started a runaway process in ipython notebook, and I had to kill the ipython process. When I stared ipython notebook server again and connected with my browser, suddenly the toolbar labels are missing (see attached screenshot)
I have tried restarting my machine and starting ipython notebook anew, but this did not help.
Can somebody please advise how I can restore the toolbar labels?
