Large-scale image classification models on Keras

This is a collection of large-scale image classification models. Many of them are pretrained on ImageNet-1K dataset and loaded automatically during use. All pretrained models require the same ordinary normalization. Scripts for training/evaluating/converting models are in the imgclsmob repo.

Installation

To use the models in your project, simply install the kerascv package with desired backend. For example for MXNet backend:

pip install mxnet>=1.2.1 keras-mxnet kerascv

Or if you prefer TensorFlow backend:

pip install tensorflow kerascv

To enable/disable different hardware supports, check out installation instruction for the corresponding backend.

After installation check that the backend field is set to the correct value in the file ~/.keras/keras.json. It is also preferable to set the value of the image_data_format field to channels_first in the case of using the MXNet backend.

Usage

Example of using a pretrained ResNet-18 model (for channels_first data format):

from kerascv.model_provider import get_model as kecv_get_model
import numpy as np

net = kecv_get_model("resnet18", pretrained=True)
x = np.zeros((1, 3, 224, 224), np.float32)
y = net.predict(x)

Pretrained models (ImageNet-1K)

Some remarks:

All quality values are estimated with MXNet backend.
Top1/Top5 are the standard 1-crop Top-1/Top-5 errors (in percents) on the validation subset of the ImageNet-1K dataset.
FLOPs/2 is the number of FLOPs divided by two to be similar to the number of MACs.
Remark Converted from GL model means that the model was trained on MXNet/Gluon and then converted to Keras.
