I want to inference via API using gradio_client but
All OVIS model workspaces suggest that it is possible to use the model via the Hugging Face API, as shown in the example below:

from gradio_client import Client

client = Client("AIDC-AI/Ovis2-1B",  hf_token=HF_TOKEN)
result = client.predict(
        chatbot=[],
        image_input=handle_file('https://raw.githubusercontent.com/gradio-app/gradio/main/test/test_files/bus.png'),
        api_name="/ovis_chat"
)
print(result)

However, in practice, this does not work. The result is the following error:

Traceback (most recent call last):
