Describe the problem

Unit tests are failing for /object_detection/dataset_tools/oid_tfrecord_creation.py . I also encounter the the same error again originating from oid_tfrecord_creation when trying to run /object_detection/dataset_tools/create_oid_tf_record.py with the label map /object_detection/data/oid_v4_label_map.pbtxt .
