ValueError: Shapes (739, 128, 128, 3) and (128, 128, 3) are incompatible
I got below error when tried to use "transunet_2d"
model = models.transunet_2d((128, 128, 3), filter_num=[64, 128, 256, 512], n_labels=3, stack_num_down=2, stack_num_up=2, embed_dim=768, num_mlp=3072, num_heads=12, num_transformer=12, activation='ReLU', mlp_activation='GELU', output_activation='Softmax', batch_norm=True, pool=True, unpool='bilinear', name='transunet')
See below error:
