Installation: ImportError: No module named 'ale_python_interface'

[sahiliitm]

When I try to run the saved model as :

python demo_a3c_ale.py ../roms/breakout.bin trained_model/breakout_ff/80000000_finish.h5

I get an error :

ImportError: No module named 'ale_python_interface'

which is because python3.5 (which I am using now by default) does not have access to ALE.
So I installed ALE but at the ale_python_interface step, that is when we have to execute

pip install --user .

I instead execute

python3.5 -m pip install --user .

since we want python3.5 to get access to ALE. This results in a syntax error since the ALE's python code still has python2.7 syntax. How do we fix this issue?

Thanks!

pip3 install --user . is the right command.
