NEW FEATURE SUPPORT

• ContextualLoss weight
• amp support

  try_autoamp_g: True # enable amp Automatic mixed precision for network_g. if loss inf or nan or error just set to False
  try_autoamp_d: True # enable amp Automatic mixed precision for network_d. if loss inf or nan or error just set to False
  

---

TIPS

• PairedImageDataset set high_order_degradation : False
• RealESRGANDataset set high_order_degradation : True
• model_type can use GeneralGANModel or GeneralNetModel for ,ost of archs
• To use Automatic mixed precision, edit the yml
• e.g. if you want use omnisr-gan with amp, just use model_type: GeneralGANModel and edit the .yml 's following part

name: train_OmniSRGANModel_SRx4_scratch_P48W8_DIV2K_500k_B4G8
try_autoamp_g: True # enable amp Automatic mixed precision for network_g. if loss inf or nan or error just set to False
try_autoamp_d: True # enable amp Automatic mixed precision for network_d. if loss inf or nan or error just set to False
network_g:
  type: OmniSRNet
  num_in_ch: 3
  num_out_ch: 3
  num_feat: 64
  upsampling: 4
  res_num: 5
  block_num: 1
  bias: True
  block_script_name: OSA
  block_class_name: OSA_Block
  window_size: 8
  pe: True
  ffn_bias: True

• If you want to use aesrgan's network_d for other network_d. you should edit the .yml network_d to multiscale type
• e.g. if you want use omnisr as network_g and multiscale as network_d, just edit the .yml 's following part

# network structures

network_g:
  type: OmniSRNet
  num_in_ch: 3
  num_out_ch: 3
  num_feat: 64
  upsampling: 4
  res_num: 5
  block_num: 1
  bias: True
  block_script_name: OSA
  block_class_name: OSA_Block
  window_size: 8
  pe: True
  ffn_bias: True

network_d:
  type: multiscale
  num_in_ch: 3
  num_feat: 64
  num_D: 2
