WebJul 22, 2024 · We’ve selected the pytorch interface because it strikes a nice balance between the high-level APIs (which are easy to use but don’t provide insight into how things work) and tensorflow code (which contains lots of details but often sidetracks us into lessons about tensorflow, when the purpose here is BERT!). WebApr 12, 2024 · As you found, this is the expected behavior indeed where the current Parameter/Buffer is kept and the content from the state dict is copied into it. I think it would be a good addition to add the option to load the state dict by assignment instead of copy in the existing one. Doing self._parameters[name] = input_param.
