Firsy My Data Set is as follows
images folder ----> with training images of size 640x512
labels folder ---> text files for each image above with following data 0 311.489379882812 204.399459838867 36.0547180175781 24.1059265136719 i-e class label, x , y, w, h, (these values are not normalized.

I have modified preprocessinmg.py to output the dataset as required by the notebook but still I get the error

c:\Users\Usman\anaconda3\envs\tf-gpu\lib\site-packages\numpy\core\fromnumeric.py:43 _wrapit
    result = getattr(asarray(obj), method)(*args, **kwds)

ValueError: cannot reshape array of size 10 into shape (1,1,1,1,2)
