very short answer bug

[payphone131]

No matter what the input is, the output is always very short and is bad at answering the question. For example, when the query is 'what is in this image?' and the input image is a photo of a panda, the output is '1000 images about panda on pinterest'. Could you help me solve this problem? I used the official quckstart code (in https://huggingface.co/THUDM/cogvlm-base-224-hf), and have downloaded vicuna-7b-v1.5.
