Usage

A file __init__.py is contained inside this repo which contains all the code to use this model.

Firstly, clone this repo and place all the files inside a folder.

Make sure you have git-lfs installed (https://git-lfs.com)

bash

git lfs install
git clone https://huggingface.co/devasheeshG/whisper_large_v2_fp16_transformers

Please try in jupyter notebook

python

# Import the Model
from whisper_large_v2_fp16_transformers import Model, load_audio, pad_or_trim

python

# Initilise the model
model = Model(
            model_name_or_path='whisper_large_v2_fp16_transformers',
            cuda_visible_device="0",
            device='cuda',
      )

python

# Load Audio
audio = load_audio('whisper_large_v2_fp16_transformers/test.wav')
audio = pad_or_trim(audio)

python

# Transcribe (First transcription takes time)
model.transcribe(audio)
