Windos AND Linux Support here! come and get it! (easier installation too!!)

[loscrossos]

I created a fully linux and windows compatible fork.

https://github.com/mytait/Zonos

Easy Installaion

pre-requisite: make sure CUDA toolkit and drivers at least 12.4 is installed.

All you need to do to install (on any of both sytems) is:

1. create a python 3.10 environment
2. clone the repo (download it)
3. install espeak NG: (linux ubuntu apt install -y espeak-ng) (windows with the official installer at https://github.com/espeak-ng/espeak-ng/releases or easier with the command i provide in the readme)
4. run one command: pip install -r requirements1.txt -r requirements2.txt
   nothing else. then it shold run!!!

IMPORTANT: Gradio will ask you to use adress: 0.0.0.0:7860. That does not work: use http://127.0.0.1:7860/ instead

Easy as peasy or what?

I tested this on windows11 with latest updates and Ubuntu24.04 latest updates

Constraints
-I only tested cli inference with local downloaded models.
-Gradio on windows seems to display adress: 0.0.0.0:7860 use http://127.0.0.1:7860/ instead
-did not test MacOS

could you guys try it on windows/linux? then we could create a pull request if its ok by gabrielclark3330 and the others.

Changes
The full code is unchanged apart from:
-repackaged the requirements into 2 requirement files
-added 4 lines for windows to conditioning.py

no need for:
-uv
-pyproject.toml (i kept it but you dont need it anymore for normal inference i think)

HUGE CREDIT to: sdbds! i actually took his solution from #47 and the missing libraries he compiled and repackaged them in a python friendly, os-indepentent manner removing the need for the powershell script.

also i got the hints from Dao-AILab/causal-conv1d#46

details:

-linux: the installation happens in 2 phases: first pytorch then the other libs. else conv1d shows an error that it can not find torch (actually windows only needs the requirements2.txt but its nice to have a single command)
-in windows the enspeak-ng package is not seen by python so i added an environment variable to the code so its found (these are the 4 lines)

IF and only if you run into problems because MSVC (visual studio compiler) it might be because you dont have it installed or you have a wrong version. you can run this command in a command shell with admin rights to install the 2022 MSVC:

Windows11:
winget install --id=Microsoft.VisualStudio.2022.BuildTools --force --override "--wait --passive --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows11SDK.22621" -e --silent --accept-package-agreements --accept-source-agreements

rem use this on windows 10
winget install --id=Microsoft.VisualStudio.2022.BuildTools --force --override "--wait --passive --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows10SDK" -e --silent --accept-package-agreements --accept-source-agreements

or you can get the official installer from microsoft and make sure to install the compiler components as well as the windows SDK

I have it installed anyway but in other forums i read that you might need it for triton.

Not working for me. I tried building this in docker too and it seemed to get closer, but it has zonos_container | * Running on local URL: http://0.0.0.0:7860 in the output, while nothing is at the address.

[vdruts]

OMG YES. Going to try this. This install has been driving me nuts. Got your fork working in WSL2/Ubuntu.

What I will say is that the voices have TONS of emotion and are great, but are incredibly inconsistent. Every generation has too much variance in pitch/tone, and I can't possibly get anything above a sentene of similarty.

docker works in the linux part.. actually i didnt touch the code for docker. My changes are in the windows/library installation part. As long as that works without errors then your are fine. But someone reported that docker does not work in windows and apparently how to fix it in #82

EDIT: there is a bug on windows with that. use this adress instead:
http://127.0.0.1:7860/

that worked for me

[Reno0vacio]

Yap. Doesn't work..
I installed everything and run : python gradio_interface.py

[hirez19]

So sorry, i am kinda new to this, and wonder if there is a even "simpler" guide to these steps..
create a python 3.10 environment
fork the repo

I am able to move about in CMD etc. and have done several envs etc. but can someone be so kind and type up commands: like
select folder, type CMD,
git clone XXXXX
cd XXXX
Create XXXX
etc.?

Grateful for any help, as googling these things brings info overload..

[loscrossos]

@Reno0vacio it seems you have MSVC2019 installed. Try installing MSVC2022 as i said in my first post.

[aaronnewsome]

Really appreciate what you tried to do here, but for me this falls pretty short of "easier installation". I went through a few rounds of trying to install using your method, but eventually gave up, as I couldn't fight my way out of dependency hell. Your dependencies don't include "packaging". After installing packaging, the install attempt tells me I don't have torch. After installing torch, install fails and says nvcc wasn't found. Trying to install cuda and getting a screen full of errors like:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
torch 2.6.0 requires nvidia-cublas-cu12==12.4.5.8; platform_system == "Linux" and platform_machine == "x86_64", but you have nvidia-cublas-cu12 12.5.3.2 which is incompatible.

Between all the troubleshooting I did using the install instructions for the project and then trying and failing with your fork, I think I'll wait until someone puts together a guide or method for easy install or a docker container with all the components already installed.

Again, appreciate the work you put in on attempting to make this install easier.

Downgrade your cuda version:
CUDA 12.4.5.8 to match the requirements of PyTorch 2.6.0
https://developer.nvidia.com/cuda-12-4-0-download-archive?target_os=Windows
Make sure that the CUDA_PATH in the System Variables is set correctly.
or follow this method:

The gradio interfaces DOES in fact load and I was able to generate an audio file.

The reason I can't just "delete everything" as suggested above is because this system runs a very fragile stack of stuff that I don't want to come tumbling down. Anytime ANYTHING on this system is upgraded, things break. Although comfyui, ollama and everything else runs in containers, if there are cuda version mismatches within the containers, things break.

I did say in my post earlier that I was giving up after spending my entire morning on it, I kept trying for another few hours. What made the difference was starting with the nvidia-devel container with CUDA 12.2.0, which matches the CUDA version of the underlying Ubuntu 24.04.

Once the base container was up, I manually (interactively) figured out a way to get the app to start in the container. It involved installing torch==2.5.1 and then downgrading numpy to 1.26.4. For anyone who is in the same boat as me where you can't just 'delete everything', here's the Dockerfile I used to build a container that worked with my existing Cuda 12.2:

You don't even have requirements1.txt nor requirements2.txt in the repo.
What scam is this?

[loscrossos]

sorry man, i reseted the repo doing an update to the newest Zonos code.

i will reupload soon.

[tjameswilliams]

@Goury scam? Check your attitude. This is an open sourced project with contributors giving their own time.
