I am trying to train M-RCNN using Keras and RetinaNet as in the Keras founder's example. I installed retinanet package but this module isn't found. May be it is related to that my TF doesn't use GPU? How to check that?
from keras_retinanet.utils.gpu import setup_gpu
Traceback (most recent call last):
File "<ipython-input-2-1f3ae263a7c6>", line 1, in <module>
from keras_retinanet.utils.gpu import setup_gpu
ModuleNotFoundError: No module named 'keras_retinanet.utils.gpu'
