python 2 module dependency on python 3

Question

For one of the test with avocado on power architecture, I am getting an error for a dependency module as:

ERROR: No module named 'autotest'

I tried installing this module with pip and I am getting python 2 dependency error as below

 eck_version.py", line 58, in find_desired_python
         raise ValueError('Python 2.x version 2.4 or better is required')
     ValueError: Python 2.x version 2.4 or better is required
