The efficientnetv2-pytorch- from xolbynz

efficientnetv2-pytorch-'s Introduction

EfficientNetV2-S implementation using PyTorch

Steps

Configure imagenet path by changing data_dir in train.py
python main.py --benchmark for model information
python -m torch.distributed.launch --nproc_per_node=$ main.py --train for training model, $ is number of GPUs
python main.py --test for testing, python main.py --test --tf for ported weights testing

Note

The model achieved 82.7 top-1 after 150 epochs
The model ported from original TensorFlow showed 83.8 top-1
