pypoetry doc is very well written and detailed.
First, be sure to not be in a virtual env.
To install poetry with the right version :
curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | POETRY_VERSION=1.1.6 python
(on Windows, from PowerShell) (Invoke-WebRequest -Uri https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py -UseBasicParsing).Content | POETRY_VERSION=1.1.6 python -
By default, poetry will create a virtualenv in a cache-dir folder. To have it created in the repository, under a .venv folder, you need to first run poetry config virtualenvs.in-project true (https://python-poetry.org/docs/configuration/#virtualenvsin-project-boolean).
Then go to our repository, and run poetry install. It will create a virtualenv that can be used in PyCharm, with all the dependencies needed.
There may be an issue when downloading MNIST. To fix it, run:
cd ~/.avalanche/data/mnist/
wget www.di.ens.fr/~lelarge/MNIST.tar.gz
tar -zxvf MNIST.tar.gz
