Fixed an error when finding a model name in the repository while offline

[fallingmeteorite]

When I enable offline mode, "_models[model_name] = open_onnx_model(hf_hub_download())“ in the “_open_model” function looks for the model locally and returns the path,

But “_check_model_name()” is directed to access to the hf repository, which is not possible in the offline state,

This results in offline users having a model that is locally present and unusable.

Now if there is no cache model locally and HF_HUB_OFFLINE=1 is enabled, an exception will be thrown as: You have turned on environment variables, HF_HUB_OFFLINE=1, but there are no cache files locally, please unset HF_HUB_OFFLINE=1 and enable it after downloading the model

There will be no problems with normal use, and when the model is cached locally, using HF_HUB_OFFLINE=1 will work normally
