How to deal with the file bpp and computing bpp? #15

The bpp computing by the output npz file of Decoder is not equalled with the bpp compute from the net ImageCompressor. The resource image is 1920*1920, file size is 2534.633 Kb. While I save the output of ImageCompressor.Decoder(), the npz file size is 162.515 Kb. The bpp computed through the file size is 0.3526801215277778, which is much higher than the bpp_feature computed by the forward of net ImageCompressor (bpp-feature:0.09008687734603882). How to deal with the difference?
