報錯：Set TORCHDYNAMO_VERBOSE=1 for the internal stack trace (please do this especially if you’re reporting a bug to PyTorch). For even more developer context, set TORCH_LOGS=“+dynamo”

解決：

文本推理

# Text
messages = [{"role": "user","content": [{"type": "text", "text": "你是誰"}]}
]

圖像+文本推理

#   Image Onlymessages = [{"role": "user","content": [{ "type": "image", "image" : "./下載.jpg" },{"type": "text", "text": "詳細描述這張圖片"}]}
]
