TypeError: Expected binary or unicode string, got item

[CPor99]

Hi, so I am currently following a tutorial whereby I am training a custom dataset using SSD. In order to complete my dataset, I had to run the command "python generate_tfrecord.py -x [PATH_TO_IMAGES_FOLDER]/train -l [PATH_TO_ANNOTATIONS_FOLDER]/label_map.pbtxt -o [PATH_TO_ANNOTATIONS_FOLDER]/train.record", now the issue is on the label_map where it is giving me the Type error mentioned in the title.

Link to tutorial:
https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/training.html

This is how I am calling that command:
"python generate_tfrecord.py -x C:\Test\workspace\training_demo/images/train -l C:\Test\workspace\training_demo\annotations\label_map.pbtxt -o C:\Test\workspace\training_demo\annotations\train.record"

The error in the shell:
Traceback (most recent call last):
File "generate_tfrecord.py", line 62, in
label_map_dict = label_map_util.get_label_map_dict(label_map)

Thanks!
