AttributeError: module 'albumentations.augmentations.functional' has no attribute 'scale'

DESCRIPTION

vedaseg train fails getting AttributeError: module 'albumentations.augmentations.functional' has no attribute 'scale'.

REPRODUCE PROCEDURE

Use current PiPy version of albumentation and execute training. I'm using the following versions of software stacks.

docker image: pytorch/pytorch:1.7.1-cuda11.0-cudnn8-devel torch: 1.7.1 torchvision: 0.8.2 conda: 4.10.3 Python: 3.8.10 conda origin imgaug: 0.4.0 albumentation: 1.1.0 PyPi current version

ANALYSYS and SUGGESTED RESOLUTION

It looks like scale() method in albumentations.augmentations.functional does not exist in albumentations 1.1.0 any longer. The method exists at least until 0.5.1, and after downgrading albumentations train process worked.

Thus, I think nowadays it's better to write albumentations version in requirements.txt:

albumentations==0.5.1

rather than:

albumentations>=0.4.1

LOG

The below is an exerption from the stack trace I got.
