mobilenetv3 model has low accuracy #33

I tested many mobilenetv3 models and got very low accuracy. What is the problem?

Likely incorrect preprocessing, especially image mean/std for normalization. Not all models are the same. The TF mobilenetv3 uses inception preprocessing with 0.5 mean & std as per readme
