Hi, sorry. For some reasons, the previous notification emails went to the trash folder. I just noticed them today.
I posted our test code on GitHub - junwan0224/test-code 2. We used the compare.py file compare the gradients. One model has privacy engine while the other does not. We feed them the exact same data, but the resulted gradients are different.
For a previous question: yes, our noise multiplier is set as zero. Please let me know if there is any other question. Thank you for helping!
