not enough values to unpack (expected 3, got 2)

[playground]

Trying out this

python -m auto_annotate --label_map_path /datasets/sample2/label_map.pbtxt \
--saved_model_path /datasets/sample2/saved_model \
--imgs_path /datasets/sample2 \
--xml_path /datasets/sample2 \
--threshold 0.65

but got this error for all of the images
