How to resolve UnicodeError in Tensorflow 2 Object Detection API

I have a question, but when I was training the tensorflow-object-detection-API, I got the following error. Can you tell me if there is any workaround?

Conducted commnand

python model_main_tf2.py --model_dir=models/my_ssd_mobilenet_v1_fpn_640x640_coco17_tpu-8 --pipeline_config_path=models/my_ssd_mobilenet_v1_fpn_640x640_coco17_tpu-8/pipeline.config

tensorflow_check What I did -I tried to convert the character code of pipeline.config. -The API was tested. (It's OK like the attached image.) -Check if there are any mistakes in the execution command.

Also, when learning on another network, I was able to finish learning to the end without such an error. This time as well, I downloaded and ran the trained model.

We apologize for the inconvenience, but thank you for your cooperation.

Most Probably it's because you are trying to run a TPU model on your local machine(I guessed that from you PyCharm ScreenShot). Try running a GPU based model or a CPU one.
