[BUG] significant performance discrepancy
yuxiangwei0808 opened this issue · comments
I am using huggingface model zoo to reproduce the standard image classification task based on Cifar10. However, I found the huggingface's implementations, although much faster, have much worse performances compared to some common implementations.
I use timm.create_model("MODEL_NAME") to get the model without any pertaining and do the training, below are my training script and implementation of resnet18 . Similar phenomenon can also be witnessed with other models.
To Reproduce

@yuxiangwei0808 Your 'alternative' resnet is more friendly for lower resolution dataset like cifar, it has fewer stride 2 layers, no stem maxpool, the timm one is not, it's the classic imagenet oriented resnet, their weight inits are also different. Nothing unexpected here.
Ok, thanks for the response!
