I have created datablock with cls=PILImageBW, in the summary I also see it is create PILImage with mode = L , only problem is that, when I am trying to see the shape
binary = DataBlock(blocks=(ImageBlock(cls=PILImageBW), MaskBlock(codes)),
get_items=get_image_files,
splitter=RandomSplitter(),
get_y=get_y,
item_tfms=RandomResizedCrop(460, min_scale=0.5),
batch_tfms=[*aug_transforms(size=256, min_scale=0.75),
Normalize.from_stats(*imagenet_stats)])
x, y = dls.one_batch()
The shape seems to have 3 channels
torch.Size([8, 3, 256, 256]), torch.Size([8, 256, 256]))
May be some context why I wanted to have 1 channel image, The final model will be converted to onnx model. So I want to have one channel image, otherwise there will be some complexity on the developement side expected. Please let me know whether my problem description is understandable
