In the original mock_auto_tokenizer fixture, we were mocking the transformers.AutoTokenizer.from_pretrained
|
|
method directly, but we were not providing a return value for this method. Therefore, when from_pretrained
|
|
was called within HuggingFaceTGIChatGenerator, it returned None because that's the default behavior of a
|
|
MagicMock object when a return value isn't specified.
|
|
|
|
We will update the mock_auto_tokenizer fixture to return a MagicMock object when from_pretrained is called
|
|
in another PR. For now, we will use this fixture to mock the AutoTokenizer.from_pretrained method.
