How to use this project on Apple's M1 chip.

[Zengyi-Qin]

If you wanted to try a demo, please use the lepton or myshell link, instead of running on M1. If you wanted to deploy it by yourself, please use a ubuntu 20.04 environment. In neither situation we recommend running on M1.

[iamshreeram]

@Zengyi-Qin , The demo appears to be functioning well on Ubuntu. However, when attempting to run the torch with "device" set as MPS for Mac M1, I encountered the following error:

Loaded checkpoint 'checkpoints/base_speakers/EN/checkpoint.pth'
missing/unexpected keys: [] []
Loaded checkpoint 'checkpoints/converter/checkpoint.pth'
missing/unexpected keys: [] []

Considering the widespread usage of Mac computers in various workplaces, it would be advantageous to ensure compatibility with Mac systems. Exploring possibilities on a Mac would broaden the range of individuals who could benefit from the demo and make it more accessible to potential users.

Please let me know if could provide support, as I would like to consider the possibility of making openvoice compatible with Mac.

[Zengyi-Qin]

@iamshreeram The output you showed is not an error. Please safely ignore it. And regarding Mac compatibility - Could you make this repo Mac-compatible and create a pull request? Very much appreciated

[cchance27]

@iamshreeram just to be clear

Loaded checkpoint 'checkpoints/base_speakers/EN/checkpoint.pth' missing/unexpected keys: [] [] Loaded checkpoint 'checkpoints/converter/checkpoint.pth' missing/unexpected keys: [] []

isn't an error thats just that it loaded correctly and no keys were missing or unexpected, realistically they could probably wrap that in an if statement and if there are none just don't print the blank arrays.

[iamshreeram]

Thank you for clarifying, @cchance27 . Great, @Zengyi-Qin. I appreciate the support.

I have begun working on a fork to incorporate Mac support, which can be found at this link - https://github.com/iamshreeram/OpenVoice/blob/main/demo_mps.ipynb While attempting the inference, I am encountering an error. I suspect that there is an issue with the dimensions when running on a Mac computer.

@iamshreeram Working on this too - will let you know if i get with working on my M1.

suggestion: missing/unexpected keys: [] [] should only be raised if there actually are missing or unexpected keys - it's misleading showing it when not needed.

[iamshreeram]

@AaronWard - Excellent, once the code is working correctly, we can push it to the main repository. Instead of cluttering this issue, let's carry on the conversation on https://github.com/iamshreeram/OpenVoice/discussions/1 for more comprehensive information.

[iamshreeram]

@Zengyi-Qin / @wl-zhao , The app functions properly when executed through gradio, but encounters above error issues when used in a jupyter notebook. We are experiencing an error during the inference process, specifically at the below mentioned step.

base_speaker_tts.tts(text, src_path, speaker='default', language='English', speed=1.0)

What are the distinctions between these two methods? It would be appreciated if you could engage in this discussion to help resolve the matter further. Here is the link: https://github.com/iamshreeram/OpenVoice/discussions/1

Set device as cpu is a temporary plan device = 'cpu'

[ehartford]

hello. please support mac.

[iamshreeram]

Hey @ehartford , Are you experiencing any issues with the current code base on your Mac. I was under the impression that it should already be compatible (Just that MPS is not compatible due to the issue with dependency). Could you please let us know if you're facing any challenges. thanks!

[XP20225]

Which code areyou talking about? @iamshreeram
