I still find that the output is very different since I’ve checked element sum of output feature maps are different each other (for c++ 180000 and for python 90000). But due to the project deadline, I priorly translate other modules of the entire model.
I should use a constant input as you advice and check the dropout layers! And yes, I call model.eval() when I use my model as well.
It was a great help and I really appreciate it ! After doing the rest of the translation task, I will check all of your advice again!
