Question about playback training please #95

Open yehemin opened 8 months ago

yehemin commented 8 months ago

sample_depth_heightmap = sample_depth_heightmap.astype(np.float32) / 100000 Why does the variable sample_depth_heightmap divide by 100000 and then feed the data into the network. Not in the playback training is directly inputting depth_heightmap without dividing by 100000. May I ask why?
