Why do we need the following in the Fine-tuning LayoutLMv2ForSequenceClassification on RVL-CDIP notebook?

# we need to define custom features
features = Features({
    'image': Array3D(dtype="int64", shape=(3, 224, 224)),
    'input_ids': Sequence(feature=Value(dtype='int64')),
    'attention_mask': Sequence(Value(dtype='int64')),
    'token_type_ids': Sequence(Value(dtype='int64')),
    'bbox': Array2D(dtype="int64", shape=(512, 4)),
    'labels': ClassLabel(num_classes=len(labels), names=labels),
})

Hi,

I should actually update this notebook as now we can use the native Image feature rather than Array3D for the image column. Did you try to run the code without defining custom features, and if so, did it work?
