I did not change the algorithm. Later, I used the modified model to inference, and it seemed to be normal. Recently, I continued training with this modified model, no error was reported, and I saw that the newly saved model size returned to the previous 526,153,469 Bytes. So it’s a mystery, although I don’t know what is the reason behind it, I guess it’s caused by the secondary compression, but I didn’t verify it, since I use it without problems, so I didn’t go into it.
