SwinUnet deprecation error and when correct TypeError over img_size

[joaomamede]

Describe the bug
Img_size argument is required, but not allowed at the same time

To Reproduce
print_config()

MONAI version: 1.5.dev2450
Numpy version: 1.26.4
Pytorch version: 2.5.1
MONAI flags: HAS_EXT = False, USE_COMPILED = False,

device = torch.device("cuda:0")
model = SwinUNETR(
    img_size=(512,512,64),#this is not an argument anymore
    spatial_dims=3,
    in_channels=2,
    out_channels=3,
    feature_size=48,
    drop_rate=0.0,
    attn_drop_rate=0.0,
    dropout_path_rate=0.0,
    use_checkpoint=True
    
).to(device)

DeprecatedError: Argument img_size was removed in version 1.5. The img_size argument is not required anymore and checks on the input size are run during forward().

But

model = SwinUNETR(
    # img_size=(512,512,64),#this is not an argument anymore
    spatial_dims=3,
    in_channels=2,
    out_channels=3,
    feature_size=48,
    drop_rate=0.0,
    attn_drop_rate=0.0,
    dropout_path_rate=0.0,
    use_checkpoint=True
    
).to(device)

TypeError: missing a required argument: 'img_size'

Expected behavior
Img_size is no longer needed but we have type error when not present and DeprecationError when present.

Environment

anaconda linux ubuntu 24.04

python -c "import monai; monai.config.print_debug_info()"

Hi @joaomamede, may I ask how did you install the monai?

Hi @joaomamede, may I ask how did you install the monai?

Good question I think I did pip install. It was a while back.

If I remove the deprecation type error in the code the swin runs.

Hi @joaomamede, yes. I know it's a bit of a mismatch, because we want to tell the user something through the deprecate message, but because the img_size doesn't have a default value, if we add a default value for it and change the position of the parameter, it may cause some users get error who specifying the parameters in order. Theoretically, if your monai version doesn't start with 1.5, there won't be a problem.
