Validation

I see that you have validation turned off in your training script:
https://github.com/alibaba/ClickSEG/blob/d61a76b2c88c56106e97d505ce41d16aa2535021/isegm/engine/baseline_trainer.py#L125

Moreover, the code would not work because of https://github.com/alibaba/ClickSEG/blob/d61a76b2c88c56106e97d505ce41d16aa2535021/isegm/data/transforms.py#L8
This should be

```
from albumentations.augmentations.geometric import functional as F
```

because that's where `resize()` is located.

Now, the question: did you use those validation augmentations to come up with the training schedule? How important are they?

Start with isegm/engine/baseline_trainer.py at line 125 and isegm/data/transforms.py at line 8. Check how validation augmentations are enabled and how they relate to the training schedule, then verify the transforms import and determine whether validation augmentations affected training. Done means the import issue is resolved and the role of those augmentations is clearly established.
