Error with Python Version, but Python Version is valid?

Question

I'm getting errors with installing rasa via pip. The error message is shown as below, and it seems to suggest that my Python version isn't applicable, but my Python version is 3.11.3, which is definitely above 3.4. Does anyone have any suggestions on what this could be?

Answer 1

This is caused by an incorrect version comparison in the setup.py of absl-py-0.9.0.tar.gz which contains the line

py_version = platform.python_version_tuple()
if py_version < ('2', '7') or py_version[0] == '3' and py_version < ('3', '4'):
  raise RuntimeError('Python version 2.7 or 3.4+ is required.')

platform.python_version_tuple() is a tuple that is ('3', '11', '4'). Due to the way tuple comparison works in python ('3', '11', '4') < ('3', '4') evaluates to True. I would recommend:

1. Download absl-py-0.9.0.tar.gz from pypi
2. Extract the content, open the setup.py and comment the above mentioned lines
3. Run python setup.py install in the extracted directory

which manually disables this error.

Note rasa - which you originally tried to install does not seem to be tested or doesn't support python 3.11, because its dependencies cannot be installed without manual work. It might still work, but more likely, you will have to downgrade your python version
