Hi there!
I appreciated a lot for providing this tensorflow implementation of densenet. But when I running it on my own dataset, some warnings/errors appear and I don't know why. And I think they somehow affect the training process and results.
I searched this on stackoverflow and only found limited answers, including https://stackoverflow.com/questions/52607063/tensorflow-warning-the-graph-couldnt-be-sorted-in-topological-order. The answer says it's related with the design of graph.
I'm kind of confused. Could you help me figure this out?
The warnings/errors:
