AttributeError: 'FieldInfo' object has no attribute 'in_'

Hello all, excited about this project!

I followed the setup instructions, downloaded the models, and executed python matte_anything.py to launch the server. That command fails with the following error:

Traceback (most recent call last):

Seems that it might be related to Gradio/FastAPI, so I will try with a different version. I am currently using an Anaconda environment with the following versions:

• python==3.10.12
• gradio==3.38.0
• fastapi==0.100.0

Thanks for your help. Looking forward to trying this.

One more version that might be helpful: pydantic==2.1.0

Hello！I am really glad that you are interested in our work！Thank you for your asking！ We consider this problem may be due to the different version of fastapi and pydantic. I solve this problem by updating them, with the code:

pip install --upgrade fastapi pydantic

At present, fastapi==0.100.1 pydantic==2.1.1. I hope this answer will help you.

Worked for me! Thanks a lot for your help.
