pytonpath ???

See original GitHub issue

hi again,

I installed the repo as stated in README. in my ~/.bashrc I added “export PYTHONPATH=/home/ivision/keras-retinanet:$PYTHONPATH”

I am getting the following error message. Is this an installation issue or does it has something to do with my python path? Cause I changed the class names in ~/keras-retinanet/keras_retinanet/preprocessing …

Thanks!
