Describe the problem

I am having trouble loading mobilenet_v3_edgetpu checkpoints and measuring top-1 accuracy.

1. for 1.0 version: I'm able to restore the checkpoint and run inference, but can't replicate the documented accuracy. I'm getting somewhere between 72%-73% vs. the expected over 75%.
   I thought the problem was not using the ExponentMovingAverage weights, but after fixing the code the accuracy further drops to about 64%.
2. for 0.75 version: I'm unable to load the checkpoint at all. I use the depth_multiplier arguments and set it to 0.75. When loading the checkpoint I get:

tensorflow.python.framework.errors_impl.InvalidArgumentError: Restoring from checkpoint failed. This is most likely due to a mismatch between the current graph and the graph from the checkpoint. Please ensure that you have not altered the graph expected based on the checkpoint. Original error:
