All the functions and scripts were tested on Python 3.6, PyTorch 0.4.1 and Cuda 9.2, the operation is not guaranteed with other configurations. The command to create the CONDA environment:
conda env create -n env_cnn_nlm -f environment.yml
The command to anctivate the CONDA environment:
conda activate env_cnn_nlm
Please download the datasets using the provided script:
bash download_sets.sh
python generate_noisy_synthetics.py
Use demo_sync.py to execute a demo.
The command to train the network on synthetic data:
CUDA_VISIBLE_DEVICES=0 python experiment_sarcnn17.py --exp_name new_train
The command to test the network on synthetic data:
CUDA_VISIBLE_DEVICES=0 python experiment_sarcnn17.py --eval --eval_epoch 50 --exp_name new_train
NOTE: the SSIM of the paper is little different because it was computed using Matlab instead of Python.
