Hi MONAI team, In the notebook [`spleen_segmentation_3d_visualization_basic.ipynb`](https://github.com/Project-MONAI/tutorials/blob/main/3d_segmentation/spleen_segmentation_3d_visualization_basic.ipynb), there is a small typo in the UNet parameter dictionary variable name. The code defines: ```python UNet_meatdata = { "spatial_dims": 3, "in_channels": 1, "out_channels": 2, "channels": (16, 32, 64, 128, 256), "strides": (2, 2, 2, 2), "num_res_units": 2, "norm": Norm.BATCH, } model = UNet(**UNet_meatdata).to(device) ``` I believe **meatdata** is a typo and should be **metadata**. It’s a small issue, but it might confuse some readers — especially those new to MONAI or medical image segmentation. Thanks a lot for the great tutorials and amazing work you do with MONAI!
