Label_Map: a bytes-like object is required, not 'str'

Hi,
I am a beginner so please help me out with this.
I am running this command to train a mask model but it gives me error no matter whatever I changed.
Here are some details:

custom code: Nope
Command: python model_main.py --logtostderr --model_dir=/home/mousam/Downloads/Dogs/model/ --pipeline_config_path=/home/mousam/.keras/datasets/mask_rcnn_inception_resnet_v2_atrous_coco_2018_01_28/pipeline.config
