whisper: CrisperWhisper results in grpc: error while marshaling: string field contains invalid UTF-8

Open markuman opened this issue 9 months ago • 4 comments

LocalAI version: localai/localai:v2.26.0-aio-gpu-nvidia-cuda-12

Environment, CPU architecture, OS, and Version:

uname -a
Linux gpu2 6.13.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 13 Mar 2025 18:12:00 +0000 x86_64 GNU/Linux

Describe the bug

Using https://huggingface.co/nyrahealth/CrisperWhisper with local-ai resullts in

Whisper-Error: 500 - {"error":{"code":500,"message":"rpc error: code = Internal desc = grpc: error while marshaling: string field contains invalid UTF-8","type":""}}

To Reproduce

  1. create directories and install dependencies
mkdir CrisperWhisper
mkdir CrisperWhisper-out
pip install huggingface_hub  torch numpy transformers
git clone https://github.com/openai/whisper
git clone https://github.com/ggerganov/whisper.cpp
  1. Download the model
from huggingface_hub import snapshot_download, login

HUGGINGFACE_TOKEN = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

login(token=HUGGINGFACE_TOKEN)

model_id = "nyrahealth/CrisperWhisper"  # Replace with the ID of the model you want to download
snapshot_download(repo_id=model_id, local_dir="CrisperWhisper")
  1. convert model to single file ggml
python whisper.cpp/models/convert-h5-to-ggml.py CrisperWhisper/ whisper/ CrisperWhisper-out/

move CrisperWhisper-out/ ggm file to your local-ai model path.

Expected behavior

Transcribe succeeded without any errors.

Using CPU-based local-ai results in the same error

quay.io/go-skynet/local-ai:v2.26.0-aio-cpu

Hi - can you please share logs with --debug ?

also, can you try to set a model name without the "."? I don't think it's a problem per-se, but the UTF-8 error is unexpected. Can you also share how are you calling the API?

also, can you try to set a model name without the "."?

hmm I don't understand this.

curl -s http://localhost:8080/models|jq|grep -i -A 2 -B 2 cris 
    },
    {
      "id": "CrisperWhisper.bin",
      "object": "model"
    },

That's also just the name in the filesystem

ls -lh localai/models/ |grep -i cr
-rw-rw---- 1 markuman markuman 2.9G Mar 17 07:58 CrisperWhisper.bin

Can you also share how are you calling the API?

import requests
import json


baseurl = "http://127.0.0.1:8080"
transcription = '/v1/audio/transcriptions'

testfile = 'test.mp3'

# transcription with whisper
############################
with open(testfile, "rb") as audio_file:
    files = {"file": ("test.mp3", audio_file)}
    data = {"model": "CrisperWhisper.bin"}
    response = requests.post(baseurl + transcription, files=files, data=data)

print(response)

if response.status_code == 200:
    raw = response.json().get('text')
else:
    print(f"Whisper-Error: {response.status_code} - {response.text}")

print(raw)

I'm experiencing the very same issue. Happens only for CrisperWhisper model, all other Whisper models I tried so far just work fine. Any further details I can provide to debug this? I'd love to get CrisperWhisper running...

local-ai Version: v2.28.0
