Transfer learning in NLP Part III: Fine-tuning a pre-trained model // under NLP July 2019 Transfer learning filtering. Install other dependencies, including torchvision. This is the point where we verify that Caffe2 and PyTorch are computing the same value for the network. 6 is out with OpenAI’s pre-trained GPT-2 small model & the usual accompanying example scripts to use it. It seems that the checkpoint and the created model layers names and shapes don't match. PyTorch includes six model architectures based on convolutional networks. Conclusion. The blog post summarizes the workflow they are using to make fast and accurate TensorFlow to PyTorch conversions and share some lessons learned from reimplementing a bunch of TensorFlow models in the pytorch-transformers open-source library.
