MobileNetV2 is a convolutional neural network architecture that seeks to perform well on mobile devices. It is based on an inverted residual structure where the residual connections are between the bottleneck layers. The intermediate expansion layer uses lightweight depthwise convolutions to filter features as a source of non-linearity. As a whole, the architecture of MobileNetV2 contains the initial fully convolution layer with 32 filters, followed by 19 residual bottleneck layers.

Sign up and login in ImageNet official website, then choose 'Download' to download the whole ImageNet dataset. Specify /path/to/imagenet
to your ImageNet path in later training process.
The ImageNet dataset path structure should look like:

Set data path by export DATA_PATH=/path/to/imagenet
. The following command uses all cards to train:
bash train_mobilenet_v2_amp_dist.sh
