gdsr's Issues

Given groups=1, weight of size 32 64 3 3, expected input[7, 3, 32, 32] to have 64 channels, but got 3 channels instead

Hi there, I am currently trying to reproduce your project and have faced some issues that I cannot resolve, I was wondering if you could help me?

I am currently running pretrain for DualSR using python train.py -opt options/train/DualSR_pretrain.json , the JSON configs are as follows:

{
  "name": "12_21_01_Dual_RRDB_128_GAN_x4_DIV2K",

    }
  },

  },

  "train": {
    "lr_G": 5e-5,

    "lr_steps": [
      200000,

  },
  "logger": {
    "print_freq": 200,
    "save_checkpoint_freq": 1e3
  }
}

the output shows a mismatch between input channel size

Is there something I did wrong? Thanks in advance!
