Error running gradio demo

[prachigarg23]

Hi @hhhhzp @leexinhao ,

Thanks for your really cool work. I am running into the following bug when running the bash gradio_demo.sh script. I modified the model_name in internvl/serve/app.py to "MCG-NJU/VideoChatOnline-4B" so HF can automatically download it and made demo.launch(share=True) for running on remote server.

Even the gradio demo link doesn't work.

This seems to be an issue related to the gradio version. Can you run other gradio programs correctly?

[prachigarg23]

Hi, yes, I am using the latest gradio version. Here is the full error trace. There seems to be an issue with the gradio utils.py schema. There seems to be a TypeError in one of the schema entries but I am not sure how to isolate the variable causing it. Any inputs will be great!

@prachigarg23 Hi, could you try setting gradio==3.35.2 and gradio_client==0.2.9 in our project settings? Also, please update other frontend-related dependencies if necessary.
In my reproduction, this issue seems to be related to the frequent changes in the Gradio API across different versions.

Hi @hhhhzp , thanks for checking! After I pip installed again with these versions of gradio and gradio_client, and set demo.queue() just before demo.launch(share=True, debug=True), the gradio demo opens up. But if I try to upload a video and press start chat, I see the following error:

​I encountered the same issue with gradio==3.35.2 and gradio_client==0.2.9.
​​
Following the solution from this issue, I resolved this by:

Upgrading to ​​gradio==4.44.1​​ and ​​gradio-client==1.3.0​​
Downgrading ​to ​pydantic==2.10.6​
