Hi, I am running the Lanenet (https://github.com/MaybeShewill-CV/lanenet-lane-detection). I first train it on my desktop with tensorflow and python. Then I convert the tensorflow checkpoint to uff and run inference with tensorrt on Jetson Xavier. However, I found the results from tensorflow python and c++ tensort rt are slightly different. Please see the two picture below. Does anyone know why?

wroking on heath data set from vitalefy, i used to get the same error, converting input to np.float32 solved my issues

input_img = input_img.astype(np.float32)
