How to reproduce the issue ? (This is for errors. Please share the command and the detailed log here)
Hello everyone!

During my Riva installation, everything works except this one “pip3 install riva_api-2.3.0-py3-none-any.whl”,

Deployed with NVIDIA GPU-Optimized AMI on AWS

Received error message:
“ERROR: Could not install packages due to an EnvironmentError: [Errno 2] No such file or directory: ‘/home/ubuntu/riva_quickstart_v2.8.1/riva_api-2.8.1-py3-none-any.whl’”

Could anyone help me on that?


Hi @hulkdesign

Thanks for your interest in Riva

Apologies, riva_api-<x.y.z>-py3-none-any.whl is not longer packed with riva quickstart

Are you trying to use riva-sample app, can you share the link of the tutorial followed


Got you. The links are:

Building a Speech-Enabled AI Virtual Assistant with NVIDIA Riva on Amazon EC2 | NVIDIA Technical Blog

Please advise how to proceed from there, thanks.

Here’s another link, the system doesn’t allow more than one link

sample-apps/virtual-assistant at main · nvidia-riva/sample-apps · GitHub

Hi @hulkdesign

In replacement of unavailable riva_api-<x.y.z>-py3-none-any.whl

Please install the below package

pip install nvidia-riva-client

And use the following branch


Thanks for the input.

Upon following each individual step and executing python3 main.py, it prompted “ModuleNotFoundError: No module named ‘riva_api’”

Looks still like the riva api file issue. Could you help further on this?


BTW, just remembered that during the pip installation, it displayed like wheel file v2.8.0 but QuickStart version is 2.8.1. Not sure if the version mismatch is the reason.


Apologies that you are facing “ModuleNotFoundError: No module named ‘riva_api’”
Can you share the complete traceback

Are you sure you are using sven-update-riva-api-calls branch
can you check with git branch
