When loading a model from pretrained, you can pass the model’s name to be obtained from Hugging Face servers, or you can pass the path of the pretrained model.
On a computer with internet access, load a pretrained model by passing the name of the model to be downloaded, then save it and move it to the computer without internet access.
model.save_pretrained("./your_file_name")
In the computer without internet access, load the pretrained model by passing the path of the file you downloaded earlier and moved here.
BertModel.from_pretrained("./your_file_name")
