The efficientnet-b7-pytorch model is one of the EfficientNet models designed to perform image classification. This model was pretrained in TensorFlow*, then weights were converted to PyTorch*. All the EfficientNet models have been pretrained on the ImageNet* image database. For details about this family of models, check out the EfficientNets for PyTorch repository.
The model input is a blob that consists of a single image with the [3x600x600] shape in the RGB order. Before passing the image blob to the network, do the following:
The model output for efficientnet-b7-pytorch is the typical object classifier output for the 1000 different classifications matching those in the ImageNet database.
