I´m trying to restart the kernel in a Google Colab Jupyter Notebook through a cell. The option given previously:

import os
os._exit(00)

is ok, but it seems to me that this is not a very "pythonic" way of restarting the kernel. The other option:

from IPython.core.display import HTML
HTML("<script>Jupyter.notebook.kernel.restart()</script>")

seems more "pythonic" (better) to me, but it is not working.

Is there something specific to Google Colab that I should have done?

Best regards,

Gustavo,

    `os.exit` works. Is there some issue with that approach that is causing you to pursue an alternative? – Bob Smith Mar 05 '19 at 19:32
  • Thanks for your answer Bob. Nothing special. It is just that crashing the kernel seemed to me a "rash" alternative. The other option (using a command through the Jupyter notebook interface) seemed more elegant. In any case, your answer was excelent. Worked like a charm!.

Just go to "Runtime" in the option menu then click on "Reset all runtimes..".

tf.executing_eagerly()

I used to use this command:

condacolab KERNEL RESTART \
print("Restarting of kernel...") \
get_ipython().kernel.do_shutdown(True)

Write this on a cell and execute:

import os
os.kill(os.getpid(), 9)
