google-colab 1.0.0 has requirement ipykernel~=4.10

[woctezuma]

For information, people using Google Colab have to restart their runtime after they pip install the module.

I wonder if it would be possible to downgrade the version of ipykernel

ERROR: google-colab 1.0.0 has requirement ipykernel~=4.10, but you'll have ipykernel 5.3.4 which is incompatible.

WARNING: Upgrading ipython, ipykernel, tornado, prompt-toolkit or pyzmq can
cause your runtime to repeatedly crash or behave in unexpected ways and is not
recommended. If your runtime won't connect or execute code, you can reset it
with "Factory reset runtime" from the "Runtime" menu.
WARNING: The following packages were previously imported in this runtime:
  [ipykernel]
You must restart the runtime in order to use newly installed versions.

I have noticed this issue, when trying to pip install another PYPI module which requires addict.

My bad. I don't see which of the requirements is responsible for this.

It could be streamlit:
