ResNet50 Demo

Introduction

ResNet50 is a deep convolutional neural network architecture with 50 layers, designed to enable training of very deep networks by using residual learning to mitigate the vanishing gradient problem.

Details

  • The entry point to the Metal ResNet model is ResNet in ttnn_functional_resnet50_new_conv_api.py.
  • The model picks up certain configs and weights from TorchVision pretrained model. We have used torchvision.models.ResNet50_Weights.IMAGENET1K_V1 version from TorchVision as our reference.
  • Our ImageProcessor on the other hand is based on microsoft/resnet-50 from huggingface.

Performance

TGG

End-to-End Performance

  • For end-to-end performance, run
  pytest models/demos/tgg/resnet50/tests/test_perf_e2e_resnet.py::test_perf_trace`
  • This will generate a CSV with the timings and throughputs.
  • Expected end-to-end perf: For batch = 16 per device, or batch 1024 in total, it is about 145,000 fps currently. This may vary machine to machine.
