Import error with local file

[colt]

Hello. When I try to run a python file

python optimizer.py

it says

ImportError: No module named optimizers.PSO

There is a file called "PSO.py" on the folder "optimizers", that happens to be on the same directory where "optimizer.py" it is:

So, it is all about showing python this PSO.py? If yes, how can I do that? Many thanks

Try python -m optimizers.optimizer perhaps.
