Audio 2 Face Extension - PiP install

Omniverse General Discussion
1

Hello

I’m trying to install the required modules through my python only extension for A2F 2023.2.0 as indicated here. I have the extension fully working in Omniverse Code 2022.3.3 so i can confirm that i am able to run the extension successfully and stream audio to Audio 2 Face. The problem is when i try to load the extension in Audio 2 Face.

Required pip packages to be installed for A2F 2023.1
grpcio==1.51.3
numpy==1.22.4
scipy==1.8.1
sounddevice==0.4.2
protobuf==3.17.3

I can verify that protobuf 3.17.3 and grpcio 1.51.3 is already installed on my system and that is the version that is detected in A2F when i use the script editor in A2F.

import google.protobuf
print(google.protobuf.__version__)

import grpc
print(grpc.__version__)

“protobuf==3.17.3” and “grpcio==1.51.3” for my A2F extension.
I i use the above in my .toml file like this

[python.pipapi]
requirements = ["requests", "scipy.io.wavfile", "subprocess", "json", "os", "numpy", "IPython", "nvidia-riva-client", "protobuf==3.17.3", "grpc==1.51.3", "sounddevice==0.4.2"]
use_online_index = true

I get these errors

2024-04-05 07:26:08  [Error] [omni.kit.pipapi.pipapi] Failed to import python module protobuf. Error: No module named 'protobuf'
2024-04-05 07:26:08  [Warning] [omni.kit.pipapi.pipapi] 'protobuf==3.17.3' failed to install.

...

Here are some references from NVIDIA that i’m currently looking at to see if i am doing something wrong:

From what i gather i do not need to build the extension since it is a python only extension.
But if i want the extension to load quicker or if i want to publish it i will need to build it.

If i remove both protobuf and grcpio from python.pipapi in .toml file i get this error in A2F instead. Which results ini a failiure to load for the extension. Happy to provide more detailed error msg in DM.

Still working to solve this for both Machinema and for Audio 2 Face.
I have no errors in Code

Version 1
I install in runtime in my extension.py. No istall errors but the startup is so fast so i’m not sure it does anything.

omni.kit.pipapi.install(
    package="google.protobuf",
    version="3.17.3",
    module="google.protobuf", # sometimes module is different from package name, module is used for import check
    ignore_import_check=False,
    ignore_cache=False,
    use_online_index=True,
    surpress_output=False,
    extra_args=[]
)

import google.protobuf
ver = google.protobuf('3.17.3')

Error:

Traceback:

Version 2
I install through .toml file by adding it as a requirement. Install errors ensue. It does however “think” a while before giving me the answer.

[python.pipapi]
requirements = ["requests", "scipy.io.wavfile", "subprocess", "json", "os", "numpy", "IPython", "nvidia-riva-client", "grpc==1.51.3", "protobuf==3.17.3"]
use_online_index = true

Error

2024-04-08 08:49:46  [Warning] [omni.kit.pipapi.pipapi] 'protobuf==3.17.3' failed to install.

Version 3
If i instead use google.protobuf in the .toml i get no errors. But the startup is so fast that i don’t think it actually does anyhing.

[python.pipapi]
requirements = ["requests", "scipy.io.wavfile", "subprocess", "json", "os", "numpy", "IPython", "nvidia-riva-client", "grpc==1.51.3", "google.protobuf==3.17.3"]
use_online_index = true

Even when i just use import riva.client in the extension.py i still get a protobuf error.
I’m a bit confused by this.

import riva.client

If i disable these lines the extension loads. But nothing works.

import riva.client
import IPython.display as ipd

I can confirm that my streaming to A2F still works.
It’s the sending question to LLM and riva synthesize speech that are causing some kind of havoc…

but nvidia-riva-client installs through .toml without errors…

I can confirm that IPython is installed on my system but not in Audio 2 Face.

Regarding cannot import name 'builder' from 'google.protobuf.internal' this link might help:

python - ImportError: cannot import name ‘builder’ from ‘google.protobuf.internal’ - Stack Overflow

6

I can already confirm that both grpc and protobuf are installed and they themselves are not generating any errors. However when i activate import riva.client THATS when i get the error.

I am using the specified version of protobuf(3.17.3) and grpc(1.51.3)

I’m not sure Riva and IPython gets correctly imported and i’m not sure what to do about it.
I can confirm that i have IPython on my system but A2F does not have it.
I’m not sure how to verify riva services in A2F yet.

If i try to install ipython through .toml

or if i use IPython instead. Tried a few different versions.

tried installing nvidia-riva-client 2.14.0 but it failed.
Pip install on my system worked though. The numbers in the mmiddle are Protobuf and below Grpc

IPython is installed.
4.25.3
1.60.1
NVIDIA Riva Client is installed.
7

I can verify that i can install IPython, Protobuf, GRPC and Nvidia Riva client in Omniverse Code when i start up the extension. Using this in the script editor:

import google.protobuf
import grpc
try:
    import IPython
    print("IPython is installed.")
except ImportError:
    print("IPython is not installed.")

print(google.protobuf.__version__)
print(grpc.__version__)

try:
    import riva.client
    print("NVIDIA Riva Client is installed.")
except ImportError:
    print("NVIDIA Riva Client is not installed.")

Extension system cache settings between Code and A2F is different.
Code points to: Nvidia\omniverseCache\exts
A2F points to: ov\nucleus\exts

Ran the link_app.bat got a warning for the extension path to Audio 2 Face but it said that it fixed it and printed Success! in the end. Still can’t install or enable IPython or nvidia-riva-client

Tried some of the advice in the link that youposted Ehsan.HM: python - ImportError: cannot import name ‘builder’ from ‘google.protobuf.internal’ - Stack Overflow
No success since i can’t upgrade or downgrade the A2F Protobuf version. I even tried overwriting the files manually. But it just created more problems. Re-installing A2F now to make sure it’s a clean install.

Ruling out IPython as something that i need. It is NOT a dependency.

I have now also tried what you suggested here Ehsan: Audio 2 Face - Extension - #19 by W1r3d

I actually can’t make sense of this.
If i don’t have the correct protobuf installed on my system. I am unable to send a audio stream to A2F.
This makes sense. It tells me to downgrade to something below 3.20(I used 3.17.3). If i do that i can send a stream of audio from Omniverse Code to audio to face and it will play.
I will have no errors with my extension in Code. I can use a locally deployed docker riva quickstart 2.14.0 server to synthesize the audio.

If i try to activate the extension in Audio 2 Face i get this error:

Traceback:

I have already tried to copy the protobuf folder from a more recent project into the protobuf folder for A2F.
The extenion will load then. But NONE of the A2F extensions will load. So that doesn’t work.
3.17.3 is the protobuf version A2F is using as i’ve listed before in the beginning of this post

Can you try installing iPython 7.34.0 instead of 8.23.0?

Downgrading system IPython is successful
If i try to do this through the .toml file i get this when enabling the extension in A2F

what if you install it using C:\Users\{USER}\AppData\Local\ov\pkg\prod-audio2face-2023.2.0\kit\python.bat -m pip install ipython==7.34

I’m not getting any IPython errors in A2F when activating my Extension.
