Large difference in results between TF and pytorch

[lyxxxyl]

I have found when doing feature extraction on the same images that the tf version will all have a greater number of feature points than the pytorch version, the weights I use are sp_v6 and superpoint_v6_from_tf.pth respectively and when the input is a blank image, the tf result will be the points on the four corners of the image and the pytorch result will be empty.
