Hi, can someone explain the pytorch\_model.bin file generated during the training process AND provide a link to the source code that writes it?  
A print statement during training indicates that pytorch\_model.bin is where my weights are saved. When I run: model.num\_parameters(only\_trainable=True), this gives me a number very different from the number of weights that are saved in pytorch\_model.bin (which I am viewing as a pandas dataframe following the steps here: [How To Read Binary File In Python - Detailed Guide - Stack Vidhya](https://www.stackvidhya.com/python-read-binary-file/)). Can someone clarify why these two numbers are different? Thanks!

Hi @CCole have you been able to find a solution yet? I’m currently trying to understand this myself.
