• News (2021-01): BSRNet for blind real image super-resolution will be added.

• Pull requests are welcome!

• Correction (2020-10): If you use multiple GPUs for GAN training, remove or comment Line 105 to enable DataParallel for fast training

• News (2020-10): Add utils_receptivefield.py to calculate receptive field.

• News (2020-8): A deep plug-and-play image restoration toolbox is released at cszn/DPIR.

• Tips (2020-8): Use this to avoid out of memory issue.

• News (2020-7): Add main_challenge_sr.py to get FLOPs, #Params, Runtime, #Activations, #Conv, and Max Memory Allocated.

from utils.utils_modelsummary import get_model_activation, get_model_flops
input_dim = (3, 256, 256)  # set the input dimension
activations, num_conv2d = get_model_activation(model, input_dim)
logger.info('{:>16s} : {:<.4f} [M]'.format('#Activations', activations/10**6))
logger.info('{:>16s} : {:<d}'.format('#Conv2d', num_conv2d))
flops = get_model_flops(model, input_dim, False)
logger.info('{:>16s} : {:<.4f} [G]'.format('FLOPs', flops/10**9))
num_parameters = sum(map(lambda x: x.numel(), model.parameters()))
logger.info('{:>16s} : {:<.4f} [M]'.format('#Params', num_parameters/10**6))

• News (2020-6): Add USRNet (CVPR 2020) for training and testing.
