[Question] How do I set the image input to a null value?

Question

Hi!!
I want to do some experiments with Llava. But I don't know how to set the image input to a null value.
args = type('Args', (), { "model_path": model_path, "model_base": None, "model_name": get_model_name_from_path(model_path), "query": prompt, "conv_mode": None, "image_file": image_file, "sep": ",", "temperature": 0, "top_p": None, "num_beams": 1, "max_new_tokens": 512 })()
If I set the "image_file" to None, the model will give me a error:
AttributeError: 'NoneType' object has no attribute 'split'
