Issue

I want to use my custom package in Google colab. I installed my package and other packages that are required.

But, when I import a package, let’s say logzero, Google colab says “Module Not Found Error"

My environment

Google colab Pro+ at the date 2022/10/29

My custom package is able to be built with poetry.

Check list

The package installation is successful.
I run python -m pip list | grep logzero. Yes, logzero is surely installed.
I run python -m pip install logero -U. Nothing changes.

Solution

The following procedure was correct.

generating requirements.txt with poetry.
running !pip install -r requirements.txt in the Google Colab interface.

Here are the commands.

# use pip install -r requirements.txt, instead
!cd /content/my-package &amp;&amp; make clean &amp;&amp; poetry export -f requirements.txt --output requirements.txt
!cd /content/my-package &amp;&amp; pip install -r ./requirements.txt

# use pip install -r requirements.txt, instead

!cd /content/my-package && make clean && poetry export -f requirements.txt --output requirements.txt

!cd /content/my-package && pip install -r ./requirements.txt

What was the reason?

Unknown. But, Google colab’s jupyter kernel may not recognize packages installed by python setup.py install.
