MobileNetv2 in PyTorch

An implementation of MobileNetv2 in PyTorch. MobileNetv2 is an efficient convolutional neural network architecture for mobile devices. For more information check the paper: Inverted Residuals and Linear Bottlenecks: Mobile Networks for Classification, Detection and Segmentation

Usage

Clone the repo:

git clone https://github.com/Randl/MobileNetV2-pytorch
pip install -r requirements.txt

Use the model defined in model.py to run ImageNet example:

python imagenet.py --dataroot "/path/to/imagenet/"

To run continue training from checkpoint

python imagenet.py --dataroot "/path/to/imagenet/" --resume "/path/to/checkpoint/folder"

Results

For x1.0 model I achieved 0.3% higher top-1 accuracy than claimed.

Classification Checkpoint	MACs (M)	Parameters (M)	Top-1 Accuracy	Top-5 Accuracy	Claimed top-1	Claimed top-5
[mobilenet_v2_1.0_224]	300	3.47	72.1	90.48	71.8	91.0

You can test it with

python imagenet.py --dataroot "/path/to/imagenet/" --resume "results/mobilenet_v2_1.0_224/model_best.pth.tar" -e
