PyTorch implementation of ENet: A Deep Neural Network Architecture for Real-Time Semantic Segmentation

Installation

  1. Python 3 and pip.
  2. Set up a virtual environment (optional, but recommended).
  3. Install dependencies using pip: pip install -r requirements.txt.

Usage

Run main.py, the main script file used for training and/or testing the model. The following options are supported:

python main.py [-h] [--mode {train,test,full}] [--resume]
               [--batch-size BATCH_SIZE] [--epochs EPOCHS]
               [--learning-rate LEARNING_RATE] [--lr-decay LR_DECAY]
               [--lr-decay-epochs LR_DECAY_EPOCHS]
               [--weight-decay WEIGHT_DECAY] [--dataset {camvid,cityscapes}]
               [--dataset-dir DATASET_DIR] [--height HEIGHT] [--width WIDTH]
               [--weighing {enet,mfb,none}] [--with-unlabeled]
               [--workers WORKERS] [--print-step] [--imshow-batch]
               [--no-cuda CUDA] [--name NAME] [--save-dir SAVE_DIR]

For help on the optional arguments run: python main.py -h

Examples: Training

python main.py -m train --save-dir save/folder/ --name model_name --dataset name --dataset-dir path/root_directory/

Examples: Resuming training

python main.py -m train --resume True --save-dir save/folder/ --name model_name --dataset name --dataset-dir path/root_directory/

Examples: Testing

python main.py -m test --save-dir save/folder/ --name model_name --dataset name --dataset-dir path/root_directory/

Project structure

Folders

  • data: Contains code to load the supported datasets.
  • metric: Evaluation-related metrics.
  • models: ENet model definition.
  • save: By default, main.py will save models in this folder. The pre-trained models can also be found here.

Files

  • args.py: Contains all command-line options.
  • main.py: Main script file used for training and/or testing the model.
  • test.py: Defines the Test class which is responsible for testing the model.
  • train.py: Defines the Train class which is responsible for training the model.
  • transforms.py: Defines image transformations to convert an RGB image encoding classes to a torch.LongTensor and vice versa.
