errors about training your own model

[FortuneSeeker]

I run into these errors while training the network with my own dataset(converted by the create_dataset.py in the project): python 3.7 Have anyone met this problem? I don't know what caused it. Thank you in advance for your answer.

While creating the lmdb dataset, script loads the image file as binary so change the with open('image/path/file.png', 'r') to with open('image/path/file.png', 'rb') this will read the file as bytes instead of string.
