I changed from 2.7 to 3.6 but am having problems with the model zoo.  The Imagenet example will download pre-trained weights using a hickle file.  Unfortunately it seems that the hickle module is not compatible with Python V 3.* due to the way strings are handled, which makes it difficult to use the pre-trained examples.
Does anybody know a way around this, I don’t  want to have to go back to 2.7 if I can avoid it
