You’re not the only one. I also experienced this problem. Setting from_tf to True only yields
OSError: Can't load weights for 'EleutherAI/gpt-neo-2.7B'. Make sure that:

- 'EleutherAI/gpt-neo-2.7B' is a correct model identifier listed on 'https://huggingface.co/models'

- or 'EleutherAI/gpt-neo-2.7B' is the correct path to a directory containing a file named one of pytorch_model.bin, tf_model.h5, model.ckpt.
