libc++abi: terminating due to uncaught exception of type std::runtime_error: [AddMM::eval_cpu] Currently only supports float32. Abort trap: 6

[joshuachen3333]

In my MacBook Pro (intel i5 cpu 16GB ram), with the following config, I did my test like this:

• environment

MacOS 14.3
Xcode 15.2
kMDItemVersion = "2.8.5"
Apple clang version 15.0.0 (clang-1500.1.0.2.5)
Python 3.11.7

• install miniconda

conda create -n video_summarize_mlx python=3.11
conda activate video_summarize_mlx
git clone https://github.com/Peter-obi/Video_summarization_mlx
cd Video_summarization_mlx

• comment out the following lines of requirements.txt

# mlx
# mlx-lm

because they can not be installed by pip

pip install mlx
ERROR: Could not find a version that satisfies the requirement mlx (from versions: none)
ERROR: No matching distribution found for mlx

• install pkgs in requirements.txt by pip

pip install --upgrade pip
pip  install -r requirements.txt

• install the remaining pkgs by conda

conda install -c conda-forge mlx mlx-lm

and to run the code like this:

python -m spacy download en_core_web_sm
python main.py --input_path "/Users/joshua/video/test1.mp4" --title "test1"

• but getting libc++abi: terminating due to uncaught exception of type std::runtime_error: [AddMM::eval_cpu] Currently only supports float32. Abort trap: 6

MLX is an array framework for machine learning on Apple silicon ie M chips (read more here: https://github.com/ml-explore/mlx). Seems you have an Intel chip. First thoughts: you can swap out the whisper part for a compatible whisper one and then change the mlx model portions to 'normal' huggingface models.

Similar issue for me on an M2 Mac Air.

I will try to recreate the issue when I get back on my system. Some things you can try, make sure you are not running out of memory (happened once when I used a bigger model), also there are discussions on this here: conda/conda#9589, apple/ml-stable-diffusion#8, try also summarize_with_mlx instead of summarize_in_parallel to see if that helps (if it is a memory issue).

[az-boromir]

it is decode_result = model.decode(segment, options)
inside decode_with_fallback that is breaking, will continue seeing if I can find out what the issue is.

printing out the segment shows:
array([[-0.39502, -0.39502, -0.39502, ..., -0.39502, -0.39502, -0.39502],
[-0.39502, -0.39502, -0.39502, ..., -0.39502, -0.39502, -0.39502],
[-0.39502, -0.39502, -0.39502, ..., -0.39502, -0.39502, -0.39502],
...,
[0.575195, 0.70752, 0.590332, ..., -0.39502, -0.39502, -0.39502],
[0.603516, 0.728516, 0.655762, ..., -0.39502, -0.39502, -0.39502],
[0.599609, 0.740723, 0.674316, ..., -0.39502, -0.39502, -0.39502]], dtype=float16)

and the error is:
libc++abi: terminating due to uncaught exception of type std::runtime_error: [AddMM::eval_cpu] Currently only supports float32.

could it just be a data type mismatch?

[Peter-obi]

Interesting. I have never faced this particular issue, because I just use the already converted whisper from mlx examples and haven't ran into issues yet. Can you add this and see what happens: mel_segment = mel_segment.astype(mx.float32)?

[joshuachen3333]

Could this be apple silicon M1 M2 only issue?
I did it at a intel i5 platform.
If yes , could I run it at a Linux i7 Nvidia env? How difficult is it to port to Linux x86_ 64 env?

This didnt work. I changed the transcribe call to def to putting fp16 to false (def transcribe(audio_file, fp16=False, output_path="files/transcripts"):), and that issue is fixed, however I get a similar error when it is doing the summarize_with_mlx. I have the 4bit mixtral.

Audio has been transcribed in 22 seconds
Found 1 chunks. Summarizing using MLX model...

Looking at this, I may be missing something though. The 4bit model shouldnt need a float 32 I think.

[Peter-obi]

Great that you solved that! Been busy for a couple of weeks. Have you solved the resource_tracker error? I reproduced the error but only at the Whisper level and it was always because I ran a big model or a very long input, and it was always solved by using a smaller model or breaking the input into smaller chunks.
