Can't run inference.py properly.

[hsnu145522]

Thank you for your excellent work.
I'm trying to run inference.py but can't run it properly.
I'm not sure if it's probably caused by package version conflict?

I'm using Python 3.9.20 and the error is:
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/init.py", line 5, in
from .applications import FastAPI
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/applications.py", line 3, in
from fastapi import routing
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/routing.py", line 6, in
from fastapi import params
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/params.py", line 4, in
from pydantic import Schema
ImportError: cannot import name 'Schema' from 'pydantic'

If I downgrade pydantic to 1.7.4 by: pip install 'pydantic<1.8.0'
The errors turns to:
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/init.py", line 5, in
from .applications import FastAPI
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/applications.py", line 3, in
from fastapi import routing
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/routing.py", line 6, in
from fastapi import params
File ".../miniconda3/envs/EpiDiff/lib/python3.9/site-packages/fastapi/params.py", line 14, in
class Param(Schema):
TypeError: cannot create 'cython_function_or_method' instances

I have the problem of the version of fastapi and pydantic.
Can anyone help please?
