Initializing models... Error: unknown error

[milsun]

When using Swift CLI example, followed the exact commands mentioned, getting above error:

Chip: Apple M3 Max OS: 14.3.1 Xcode: Version 15.2 Apple Swift version: 5.9.2

Hi @milsun Can you share the full logs from the terminal?

[milsun]

Tried with all available tags too, same error.

[atiorh]

Thanks @milsun, could you also share your HW details? Is this an Apple Silicon Mac?

[ZachNagengast]

@milsun One more thing that would help us would be adding the --verbose flag:

swift run transcribe --model-path "Models/whisperkit-coreml/openai_whisper-large-v3" --stream --verbose

And paste the output of that here.

[milsun]

swift run transcribe --model-path "Models/whisperkit-coreml/openai_whisper-large-v3" --stream --verbose

[milsun]

Thanks @milsun, could you also share your HW details? Is this an Apple Silicon Mac?

My first comment has all the HW details.

[milsun]

Can you share the specific versions, for which it works, need to get it in place for a project I have been working on. Thanks!

[atiorh]

Thanks for adding the HW info in your earlier comment. M1 and newer (all Apple Silicon Macs) should definitely work for large-v3.

[atiorh]

@milsun I tested this command on M3 Max + macOS 14.4 which is the closest configuration I have to yours and it worked for me.

We think that you might have been impacted by an issue that tries to pull the tokenizer assets from HuggingFace Hub and they had an outage around the same time you filed this issue. Could you please try again and report back whether the problem persists?

[milsun]

Did a fresh clone and install, still the same issue.

[atiorh]

Since I am unable to reproduce even when using similar hardware and OS versions, let's try a few different commands on your side to localize the issue. Could you try changing the model version from large-v3 to large-v2 and tiny respectively and report back?

[Abhinay1997]

@atiorh I have the same issue as milsun.

Hardware:

M1 Macbook Pro 8GB
macOS 14.1.1

Setup:

1. Cloned the repo
2. Ran make to setup project and download the models

Also FYI, I ran make test --filter UnitTests to see if tokenizer loading would fail but all tests ran successfully.

[Abhinay1997]

Update:

• After running swift test --filter UnitTests, transcribe with tiny model: swift run transcribe --model-path "Models/whisperkit-coreml/openai_whisper-tiny" --audio-path ./Tests/WhisperKitTests/Resources/es_test_clip.wav --verbose is working.
• large-v2 fails with the same logs as above
• large-v3 works too. But I ran swift test --filter FunctionalTests and killed it after sometime. I assume testInitLarge() was executed and only post that large-v3 worked.

I'll see if I can reproduce this with a fresh install.
