resnest-50-pytorch

Use Case and High-Level Description

ResNeSt-50 is image classification model pretrained on ImageNet dataset. ResNeSt is stacked in ResNet-style from modular Split-Attention blocks that enables attention across feature-map groups.

The model input is a blob that consists of a single image of "1x3x224x224" in RGB order.

The model output is typical object classifier for the 1000 different classifications matching with those in the ImageNet database.

Input

Original model

Image, name - data, shape - 1,3,224,224, format is B,C,H,W where:

• B - batch size
• C - channel
• H - height
• W - width

Channel order is RGB. Mean values - [123.675,116.28,103.53], scale values - [58.395,57.12,57.375].

Converted model

Image, name - data, shape - 1,3,224,224, format is B,C,H,W where:

• B - batch size
• C - channel
• H - height
• W - width

Channel order is BGR.

Output

Original model

Object classifier according to ImageNet classes, name - prob, shape - 1,1000, output data format is B,C where:

• B - batch size
• C - Predicted probabilities for each class in [0, 1] range

Converted model

The converted model has the same parameters as the original model.
