AttributeError: 'NoneType' object has no attribute 'train'

Currently, I encounter the following error when running tools/train.py with a custom folder dataset and transform_config: null set in the config.

Traceback (most recent call last):
  File "tools/train.py", line 71, in <module>
    train()
  File "tools/train.py", line 54, in train
    datamodule = get_datamodule(config)
  File "/anomalib/anomalib/data/__init__.py", line 83, in get_datamodule
    transform_config_train=config.dataset.transform_config.train,
AttributeError: 'NoneType' object has no attribute 'train'

The config is as follows:

dataset:
  name: pv_fault_single_patch_per_module_converted_small
  format: folder
  path: ./datasets/pv_fault_single_patch_per_module_converted_small
  normal: normal
  abnormal: abnormal
  task: classification
  mask: null
  extensions: null
  split_ratio: 0.2
  seed: 0  
  image_size: 64 #224
  train_batch_size: 32
  test_batch_size: 1
  num_workers: 16
  transform_config: null
  create_validation_set: true  
  tiling:
    apply: false
    tile_size: null
    stride: null
    remove_border_count: 0
    use_random_tiling: False
    random_tile_count: 16

Where the rest corresponds to the default Padim config.

you have to update your config.yaml :)

@LukasBommes, it's due to the changes made in PR #168. Train and validation augmentations are now split. As @alexriedel1 said, configs has been modified as follows:

  ...
  test_batch_size: 1
  num_workers: 0
  transform_config:
    train: null
    val: null
  create_validation_set: false
  ...

If you update your config file, it should work

Ah, I see. Thanks a lot for clarifying this.
