I'm coding an API with FastAPI for this project TripoSR
My code at this moment is following (I only need this 2 functions):
from fastapi import FastAPIfrom gradio_app import preprocess, generate# initialise FastAPI instanceapp = FastAPI()@app.get("/tripo-api")def generator(input_image, do_remove_background: bool, foreground_ratio: float, mc_resolution, formats=["obj", "glb"]):""" Generator function, which calls preprocessing and generating function Parameters: - input_image, data type: PIL.Image.Image - do_remove_background, data type: boolean - foreground_ratio, data type: float""" # call preprocessing function with given parameters output_prepr = preprocess(input_image=input_image, do_remove_background=do_remove_background, foreground_ratio=foreground_ratio) # call generate function, based on prepocessing rv = generate(output_prepr, mc_resolution=mc_resolution, formats=formats) return {rv}The error I'm getting when I try to call this api is following:

For this I need an API, so that's the reason why I write this. If anyone know help, would be very helpful!
