Based on the ImageNet1k classification dataset, the 23 classification network structures supported by PaddleClas and the corresponding 117 image classification pretrained models are shown below. Training trick, a brief introduction to each series of network structures, and performance evaluation will be shown in the corresponding chapters.
## Evaluation environment
* CPU evaluation environment is based on Snapdragon 855 (SD855).
* The GPU evaluation environment is based on V100 and TensorRT, and the evaluation script is as follows.
