A coding error occurred while building a web gui with yolo

Question

import torch
import gradio as gr
model = torch.hub.load("./","custom", path="runs/train/exp10/weights/best.pt", source="local")
gr.Interface(inputs=["image"],outputs=["image"],fu=lambda img:model(img).render()[0]).launch()

I tried to change the encoding format, but still got an error:

import torch 
import gradio as gr 

with open("./runs/train/exp10/weights/best.pt", "r", encoding="utf-8") as f: 
    model = torch.hub.load("./", "custom", path=f, source="local") 
gr.Interface(inputs=["image"], outputs=["image"], fu=lambda img: model(img).render()[0]).launch()
