int() argument must be a string a bytes-like object or a number not 'nonetype'

could you please provide us the dataset which has been used to train your model?

I have tensorflow version '1.15.0'

The link you provided of training file from google drive is corrupted. i downloaded it twice but failed to open it, Kindly share link again

The training.zip file does not exist anymore. Would it be possible to upload it again please? I thank you very much!

facemask-detection/models-master/research/object_detection/face_mask_detection-master/training/labelmap.pbtxt; No such file or directory

I cannot find labelmap.pbtxt in training folder after unzipping it.
