Create two-channel ResNet34 model to train from scratch

Hi,
I want to train a ResNet34 architecture from scratch using two-separate gray scale images, Can someone help me with this.

15524c_patch_01_down_sampled_spatial_image

10191c_patch_01_original_mosaic_image

These are the two grayscale images I want to feed into ResNet34 network.

Thanks in Advance
