different normal map comparing with original figures

Hi, thank you for the pytorch code. It really saves my time for setting caffe env.

When comparing the results with the original figures in paper, I found the output normal was different. I'm not sure about the reason. It seems caused by n_out2 = cv2.cvtColor(n_out2, cv2.COLOR_RGB2BGR). I replace it with n_out2[:, :, (2, 1, 0)] and it works. Maybe the code changes the range of normal
