Hi guys. I used vapi_python library as it in the github and it says cannot import name 'Vapi' from 'vapi_python'. I'll attach the code

Copy code

from vapi_python import Vapi

def run_with_existing_assistant():
    vapi = Vapi(api_key='xxx')
    
    try:
        print("Starting call with existing assistant...")
        vapi.start(
            assistant_id='xxx',
            assistant_overrides={
                'variableValues': {
                    'name': 'John'
                }
            }
        )
        
        input("Press Enter to end the call...")
        
    finally:
        vapi.stop()
        print("Call ended.")

if __name__ == "__main__":
    run_with_existing_assistant()

Try reinstalling the package to ensure you have the latest version and that
Vapi
is exposed at the top level. Run:

Copy code

pip install --upgrade --force-reinstall vapi_python

Then, try your import again. If the error persists, check that there is no local file named

vapi_python.py

in your project directory, as this can shadow the installed package. Source: - [Vapi Python SDK GitHub](https://github.com/VapiAI/python)

Try upgrading the package and importing with from vapi import Vapi, or use direct API calls with requests if the SDK still doesn’t work..

It looks like you've already tried some common troubleshooting steps for this import error, such as reinstalling the package and checking for any local files that might shadow the installed package. Another approach you could try is importing with

from vapi import Vapi

instead of

from vapi_python import Vapi

, as sometimes the import path can change between versions. If the issue persists, using direct API calls with the

requests

library is also an option. Let me know if any of these steps help!

Please ensure you are using the official import path as shown below, and that there is no file named
vapi_python.py
in your project directory:

Copy code

python
from vapi_python import Vapi

If you still get the import error, try running:

Copy code

pip install --upgrade --force-reinstall vapi_python

and restart your Python environment. This should expose the

Vapi

class with the correct methods ([Vapi Python SDK GitHub](https://github.com/VapiAI/python)). Source: - [Vapi Python SDK GitHub](https://github.com/VapiAI/python)
