This repository provides a collection of efficient convolutional neural network architectures for image classification, including EfficientNet variants, EfficientNet-Lite, MobileNetV2/V3, MixNet, MNASNet, FBNet, and Single-Path NAS. All models are implemented in PyTorch with pretrained weights and support for ONNX and Caffe2 export. The library has been deprecated in favor of the more comprehensive timm library which supersedes it.
