How to check hat objects yolo can detect using detectObjectsFromImage?

Question

I want to print all the objects that yolo can detect.

I tried but could not find any solution yet!

import h5py
filename = "yolo.h5"
h5 = h5py.File(filename,'r')
#futures_data = h5['futures_data']  # VSTOXX futures data
options_data = h5['options_data']  # VSTOXX call option data
h5.close()
