kernel keeps dying in jupyter notebook

Question

Whenever I start jupyter notebook and create a new python 3 notebook I get an error message saying kernel has died. I have tried deleting and installing ipython, python3.6.5, and jupyter notebook but I still get the error message.

My cmd screen is as follows:-

[I 06:46:36.432 NotebookApp] KernelRestarter: restarting kernel (4/5), new random ports

Answer 1

Determining why jupyter notebook kernel dies can be daunting sometimes. When kernel dies as a result of library issues, you might not get any feedback as to what is causing it. Try running the code that is causing the kernel to die in a terminal or in ipython. One common issue I have identified is the use of SSE4.1 in later versions of tensorflow, which gives this error: TensorFlow library was compiled to use SSE4.1 instructions, but these aren't available on your machine. Aborted (core dumped). This will cause the kernel to die if you are using tensorflow in your code and not display any error in notebook. If this is the case, uninstall tensorflow and install with conda: conda install tensorflow==1.12.0, for instance.

Answer 2

Not the exact same issue as yours, but I found my kernel kept dying when I used the

exit()

command in one of my class methods. Removing this exit() command stopped my kernel from dying.

Answer 3

You can try reinstall Jupyter,

pip uninstall jupyter
pip install jupyter

and try again, which works in my case. I had this problem when I upgrade to Ubuntu 18.04.

Also check this thread. https://github.com/jupyter/notebook/issues/1892

Answer 4

If there are a backup of kernels, this can happen as well. I shutdown the server and it told me shutting down 4 kernels. Apparently I had some old runaway kernels. When I restarted the server, a single new fresh kernel was created and I was back in business.

Answer 5

Well, I am having the same issue but when I use matplotlib and try to plot libraries, I had the same issue with spyder. Guess trying to update libraries should solve it. Using Jupyter via Anaconda, could be a possible anaconda issue as well.

Answer 6

Please try to uninstall all of:

• ipykernel
• ipython
• jupyter_client
• jupyter_core
• traitlets
• ipython_genutils

And then install again.

it works for me after trying many others solutions. Actually, the problem of conflicting libraries causes this issue.
