您好，首先感谢您开源代码，很有帮助~

~~我注意到在train.py的34行用到了"configs/unet.yml"文件，而目前项目中时缺少该文件。想请问下您是否可以上传该文件？或者提供该文件的参考地址？ 此外或许还会有"configs/deeplabv3+.yml"这些文件也存在类似的问题？~~

感谢

Hi, your project image_seg requires "albumentations==0.5.2" in its dependency. After analyzing the source code, we found that the following versions of albumentations can also be suitable without affecting your project, i.e., albumentations 0.5.1. Therefore, we suggest to loosen the dependency on albumentations from "albumentations==0.5.2" to "albumentations>=0.5.1,<=0.5.2" to avoid any possible conflict for importing more packages or for downstream projects that may use image_seg.

May I pull a request to further loosen the dependency on albumentations?

By the way, could you please tell us whether such dependency analysis may be potentially helpful for maintaining dependencies easier during your development?

We also give our detailed analysis as follows for your reference:

Your project image_seg directly uses 22 APIs from package albumentations.

albumentations.augmentations.transforms.ElasticTransform.__init__, albumentations.augmentations.transforms.MotionBlur.__init__, albumentations.augmentations.transforms.Resize.__init__, albumentations.pytorch.transforms.ToTensorV2.__init__, albumentations.augmentations.transforms.CLAHE.__init__, albumentations.augmentations.transforms.PadIfNeeded.__init__, albumentations.augmentations.transforms.RandomRotate90.__init__, albumentations.augmentations.transforms.RandomCrop.__init__, albumentations.augmentations.transforms.Normalize.__init__, albumentations.augmentations.transforms.Cutout.__init__, albumentations.augmentations.transforms.RandomBrightnessContrast.__init__, albumentations.augmentations.transforms.GridDropout.__init__, albumentations.augmentations.transforms.RGBShift.__init__, albumentations.core.composition.Compose.__init__, albumentations.augmentations.transforms.RandomGamma.__init__, albumentations.augmentations.transforms.HueSaturationValue.__init__, albumentations.augmentations.transforms.ShiftScaleRotate.__init__, albumentations.core.transforms_interface.DualTransform.__init__, albumentations.augmentations.transforms.VerticalFlip.__init__, albumentations.augmentations.transforms.GaussNoise.__init__, albumentations.augmentations.transforms.HorizontalFlip.__init__, albumentations.augmentations.transforms.RandomScale.__init__

Beginning from the 22 APIs above, 14 functions are then indirectly called, including 13 albumentations's internal APIs and 1 outsider APIs. The specific call graph is listed as follows (neglecting some repeated function occurrences).

We scan albumentations's versions and observe that during its evolution between any version from [0.5.1] and 0.5.2, the changing functions (diffs being listed below) have none intersection with any function or API we mentioned above (either directly or indirectly called by this project).

diff: 0.5.2(original) 0.5.1
['albumentations.augmentations.transforms.MedianBlur', 'albumentations.augmentations.transforms.CropNonEmptyMaskIfExists.targets_as_params', 'albumentations.augmentations.transforms.GaussianBlur', 'albumentations.augmentations.transforms.CropNonEmptyMaskIfExists.update_params', 'albumentations.pytorch.transforms.ToTensorV2', 'albumentations.pytorch.transforms.ToTensorV2.apply', 'albumentations.augmentations.transforms.CropNonEmptyMaskIfExists.get_params_dependent_on_targets', 'albumentations.augmentations.transforms.CropNonEmptyMaskIfExists', 'albumentations.augmentations.transforms.CropNonEmptyMaskIfExists._preprocess_mask']

As for other packages, the APIs of warnings are called by albumentations in the call graph and the dependencies on these packages also stay the same in our suggested versions, thus avoiding any outside conflict.

Therefore, we believe that it is quite safe to loose your dependency on albumentations from "albumentations==0.5.2" to "albumentations>=0.5.1,<=0.5.2". This will improve the applicability of image_seg and reduce the possibility of any further dependency conflict with other projects.

你好： 作为一个新手有些问题想向你请教，这个代码是按照https://tianchi.aliyun.com/forum/postDetail?postId=198836 这个实现的吗？我看了这个代码，里面对比模板的数据 我没看到在哪？ 我自己拿初赛数据去写dataLoder 输入图片通道数是3 你这个model 要求输入通道是4 ，不太懂。 望在百忙中回答下 多谢了。
