为什么训练出现了完全噪声的结果，如图所示的原图和标签的训练对，20000+图片对（单通道灰度图）训练200epoch得到如图结果，sample_step=30,是否有朋友知道是什么原因呢

Title: Why is the training result completely noisy? As shown in the figure, the original image and label training pair are trained on 20000+ image (single channel) pairs for 200 epoch to obtain the result as shown in the figure, sample_step=30
