ResNet variations for TensorFlow.
This repository contains TensorFlow Keras ResNet models. Below, you will find the supported variants of ResNet and what weights are supported.
This repository is compatible with TF 2.2.0 even though grouped convolutions are only
supported in TF Nightly.
Grouped convolutions will be imported from
convolutions.py which is the TF Nightly version of convolution layers.
This allows the use of TPUs since they don't work with TF Nightly.
These models will not work without a GPU or TPU due to the use of grouped convolutions.
|Architecture||Weights||Top-1 Acc.||Top-5 Acc.|
|Wide ResNet-50 2||ImageNet||78.5||94.1|
|Wide ResNet-101 2||ImageNet||78.8||94.3|
|ResNeXt-50 32x4d||semi-weakly supervised||82.2||96.3|
|ResNeXt-101 32x8d||semi-weakly supervised||84.3||97.2|
There are two different preprocessing functions which are meant to be used
according to the task at hand. The first one, located in
is meant to be used for reproducing the ImageNet results. The second function
is located inside
resnet.py. This function is meant to be used for transfer learning.
The first function includes an additional resize to 256 by 256 and a central crop to 224 by 224.
