Attempting to run a FastAPI application on CentOS 7 but getting a module 'asyncio' error

I am attempting to run a simple FastAPI application on CentOS 7 but getting some errors. I will include some more details for context:

Python Version – 3.6.8
pip version – 9.0.3

I am running the application with this command: python3 -m uvicorn main:app

I keep getting this error:

Traceback (most recent call last):
  File "/usr/lib64/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    return asyncio.run(self.serve(sockets=sockets))
AttributeError: module 'asyncio' has no attribute 'run'

I was initially getting this error – /home/centos/fast_api/fastapi-tutorial/python3-venv/bin/python3: No module named uvicorn but after installing uvicorn via pip3 install uvicorn, I now get the "module ‘asyncio’ error"

Any help would be great

I have tried enabling a python virtual environment on the server but I still get the same error.

Could this be an issue with the Python version?
