an error occurs while packaging the training dataset for object-detection

[Geoyi]

an error:
`Traceback (most recent call last):
File "/Users/xxxx/.virtualenvs/ml_data_gen_py3/bin/label-maker", line 11, in

for tile in tiles.files:
AttributeError: 'numpy.ndarray' object has no attribute 'files'
original codes over there are:

    if ml_type == 'object-detection':
        max_features = 0
        for tile in tiles.files:
            features = len(tiles[tile][0])
            if features > max_features:
                max_features = features

and fixed by

    if ml_type == 'object-detection':
        max_features = 0
        for tile in labels.files:
            features = len(labels[tile])
            if features > max_features:
                max_features = features

seems worked after the fixing, if I understood the workflow correctly.

@Geoyi thanks for the report and the fix looks correct. Can you create a PR with this code + an added test for this?
