@jackliusr Did you ever resolve this issue? Facing same error ---

Same for me. I suppose there is a bug in the `from_pretrained` method, since it tries to connect to huggingface repo even when the model is fully cached. @sgugger could you please have a look? ---

No that’s not a bug, the method tries to detect if a more recent version of the model is available, which is why it connects to the repo. To work fully offline, you need to set the environment variable `TRANSFORMERS_OFFLINE` to 1 or yes (see [here](https://huggingface.co/docs/transformers/installation#offline-mode)). ---

Surely if something is trying to connect to something that doesn’t exist, that is a bug, because the code should fail gracefully and skip it, in particularly for something so unimportant as a new model that does not exist.
