Make sure you have Python 3.10 or higher installed. Preferably, you should use some kind of virtual environment.
Using virtualenv and virtualenvwrapper:
# Make virtual environment
mkvirtualenv -p $(which python3.10) --no-site-packages eq-python-client
# Active an environment later on (unless already activated)
workon eq-python-client
# Install requirements
pip install -r requirements.txt
