## What it is
A PyTorch library providing generic implementations and pretrained weights for compute-efficient image classification models such as EfficientNet, EfficientNet-Lite, MixNet, MobileNetV3/V2, MNASNet, FBNet, and Single-Path NAS. It supports ONNX and Caffe2 export and includes string-based architecture definitions for flexible block layouts.

## Use cases
- load pretrained efficientnet weights in pytorch
- export mobilenetv3 model to onnx
- image classification with efficientnet-lite
- compare mobile-friendly cnn architectures
- port tensorflow efficientnet weights to pytorch
- run inference with mnasnet or fbnet models

## When to choose
- you need pretrained weights for EfficientNet-family or MobileNet-family models in PyTorch
- you want ONNX or Caffe2 export of these architectures
- you are reproducing older research that depends on this repo

## When to avoid
- starting a new project - use timm (pytorch-image-models) instead, which supersedes this repo
- you need maintained code or recent PyTorch compatibility guarantees
- you need architectures beyond the MobileNet-block family

## Facets
- artifact type: library
- maturity: abandoned
- function: machine-learning, deep-learning, image-processing
- domain: machine-learning, computer-vision, deep-learning
- platform: python
- tags: efficientnet, mobilenet, pretrained-models, pytorch, onnx, image-classification, neural-architecture-search, deprecated
