Can I put the python program outside the darkflow root folder?

[jack-chui]

My original setting like this:

darkflow_api
    cfg
    darkflow
    build
    labels.txt
    main.py

main.py can run successful to detect the object. However, when I put main.py outside the darkflow_api folder. It cause the following problem:

main.py
darkflow_api
    cfg
    darkflow
    build
    labels.txt

Traceback (most recent call last):
