Thank you for the tutorial. When running the sample app (weather app), i get the below error.

Traceback (most recent call last):

ModuleNotFoundError: No module named 'riva_api'

When I installed riva_api, I see the below error.

ValueError: riva-apipackage andriva_apinamespace are deprecated. If you see this message, then you probably installed the package with commandpip install riva-api. This command invokes installation of latest version of nvidia-riva-clientpackage. For more info aboutnvidia-riva-client package refer to https://github.com/nvidia-riva/python-clients.

I am getting confused between riva_api and nvidia-riva-client packages. Can someone help.

I see the exact same issue with ‘Wikipedia’ QA example following this: Wikipedia Question Answering — NVIDIA Riva Speech Skills v1.8.0-beta documentation . Basically where ever i use ‘riva_api’ package. Can someone please help. Detailed instructions would help.
