  * Add EfficientNet-Lite models w/ weights ported from [Tensorflow TPU](https://github.com/tensorflow/tpu/tree/master/models/official/efficientnet/lite)
- * Add PyTorch trained MobileNet-V3 Large weights trained from stratch with this code to 75.77% top-1
+ * Add PyTorch trained MobileNet-V3 Large weights with 75.77% top-1
