Corners For Layout (CFL) PyTorch implementation

This is the adaptation of the Corners for Layout by C. Fernandez et.al (https://arxiv.org/abs/1903.08094)

This implementation has been tested under this environment:
python 3.7 , 3.8
pytorch 1.4
torchvision 0.5
cuda 10.1

Run python3 train_CFL.py to train and python3 test_CFL.py to do inference with the EfficientNet based models.

pretrained weights to use with the TFCFL models:

Update 20-07-2020: I have implemented a version of CFLPytorch called TFCFL which is CFLPytorch created by converting the model and the weights from TensorFlow CFL.

Run python3 test_TFCFL.py --conv_type Std --modelfile StdConvsTFCFL.pth to do inference with this model.

Run python3 train_TFCFL.py to train with TFCFL
