Hello @jmgirard
About that Metal enabling. I saw I gave in the wrong path for these in Makevars, - fixed that in 4c0b272

Could you retry with installing. Thanks!

Sys.setenv(WHISPER_ACCELERATE = "1")
Sys.setenv(WHISPER_METAL = "1")
remotes::install_github("bnosac/audio.whisper", force = TRUE)

jmgirard · 2024-02-01T22:25:44Z

Package installed this time without errors (just the same warnings as before about cblas_sgemm being deprecated). Running the speed test now.

jmgirard · 2024-02-02T03:56:06Z

Accelerate only = 10.24 min
Accelerate + METAL = 12.95 min
METAL only = 14.92 min
Neither = 35.22 min

jwijffels · 2024-02-02T08:55:30Z

Thanks for the timings. From the README of whisper.cpp

On Apple Silicon, the inference runs fully on the GPU via Metal:

Do you have an Apple Silicon with GPU?

jwijffels · 2024-02-02T11:26:29Z

Accelerate only = 10.24 min Accelerate + METAL = 12.95 min METAL only = 14.92 min Neither = 35.22 min

This was whisper("medium") right?

jmgirard · 2024-02-02T13:30:12Z

Yes I have an M2 chip, which is apple silicon. It was the medium model while plugged in (vs battery).

jmgirard · 2024-02-02T16:57:01Z

I was surprised that Accelerate + METAL was slower than Accelerate only. Is that expected?

jwijffels · 2024-02-02T17:17:25Z

I don´t know. Maybe ggerganov/whisper.cpp#89 can provide some hints on that.
I presume you can see your GPU card being active?
I can only show the comparison with the use of OpenBLAS.
If you use trace = TRUE as argument in the predict call, you will see the printing out of the optimisations you will also find in whisper.cpp output.

jwijffels · 2024-02-03T07:15:43Z

Can you use ´model <- whisper('medium', use_gpu = TRUE)´ that is needed when you want to use your GPU.
I´ve added this in 721cb5c to start on the cuda enabling, but metal might also need it.
I still need to document it.

jwijffels · 2024-02-03T15:08:53Z

Ah an error showing it tries to use metal. Does that give the same error with the tiny model?

jmgirard · 2024-02-03T15:12:52Z

Yes, same error.

jwijffels · 2024-02-03T15:14:57Z

Can you show the compilation trace of the installation so that I can see how it linked to Metal on your system.

jmgirard · 2024-02-03T15:17:24Z

Sure, I assume you mean this:

Thanks, will look into this later. Good to know already it is now trying to use the GPU.

jwijffels · 2024-02-04T01:14:21Z

Probably just need to put ggml-metal.metal in src folder instead of src/whisper_cpp folder or define the location of src/whisper_cpp in environment variable GGML_METAL_PATH_RESOURCES

…iable GGML_METAL_PATH_RESOURCES is set

jwijffels · 2024-02-04T18:25:23Z

Hello Jeffrey, this should be fixed now I believe with commit 908454f.
I've added that ggml-metal.metal file in the package and made sure it is referenced with environment variable GGML_METAL_PATH_RESOURCES when you call whisper("medium", use_gpu = TRUE)

Could you reïnstall and try again?

Thanks for your time. Looks like it crashed at https://github.com/bnosac/audio.whisper/blob/master/src/whisper_cpp/ggml-metal.m#L285-L303 when loading and next compiling the metal file.
Good thing is I managed to reproduce this using continuous integration. https://github.com/bnosac/audio.whisper/actions/runs/7781881608/job/21217187251. I'll look into it.

jwijffels · 2024-02-05T12:37:24Z

I did some debugging using the continuous integration. The root cause of this seems to be a conflict between R.h and the printing of the debug log.

whisper_model_load: adding 1608 extra tokens
  whisper_model_load: n_langs       = 99

  Error in whisper_load_model(out$file, use_gpu = TRUE, ...) :

I've created a branch 'metal' which disables all these R printing and when looking at the continuous integration run I can see it worked - although the continuous integration runs apparently on Mac 7 which is not sufficient for Metal (hope you have some newer Mac).

You can install as follows to test it. I'll see how can work around this printing issue later.

Note to myself: the definition of error in R_ext/Error.h which is loaded in ggml.h and is needed to cleanly exit R in case of an unexpected error conflicts with NSError * error which is used in ggml-metal.m. Don't know yet how to solve this.
