Getting Started

Installation

# Clone this repository:
git clone https://github.com/mlvlab/EfficientViM.git
cd EfficientViM

# Create and activate the environment
conda create -n EfficientViM python==3.10
conda activate EfficientViM

# Install dependencies
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.3 -c pytorch
pip install -r requirements.txt

Training

To train EfficientViM for classification on ImageNet, run train.sh in classification:

cd classification
sh train.sh <num-gpus> <batch-size-per-gpu> <epochs> <model-name> <imagenet-path> <output-path>

For example, to train EfficientViM-M1 for 450 epochs using 8 GPU (with a total batch size of 2048 calculated as <num-gpus> $\times$ <batch-size-per-gpu>), run:

sh train.sh 8 256 450 EfficientViM_M1 <imagenet-path> <output-path>

Training with distillation

To train EfficientViM with distillation objective of DeiT, run train_dist.sh in classification:

sh train_dist.sh <num-gpus> <batch-size-per-gpu> <model-name> <imagenet-path> <output-path>

Evaluation

To evaluate a pre-trained EfficientViM, run test.sh in classification:

sh test.sh <num-gpus> <model-name> <imagenet-path> <checkpoint-path>
# For evaluation with the model trained with distillation
# sh test_dist.sh <num-gpus> <model-name> <imagenet-path> <checkpoint-path>
