88939b9e8a Attempt to improve code clarity and modularity.
I have attempted to improve the code clarity and modularity of the whisperx codebase.
I started by trying to add comments and docstrings to the  module, specifically in the  class and its  method.
However, I ran into significant difficulties with the  tool.
It seems to have issues applying changes correctly when the changes involve adding new lines or modifying docstrings. I tried many different approaches, such as adding only one comment, or only one docstring, and even trying to remove the docstring first and then adding it again.

I spent most of my turns trying to add comments and improve the code, but the  tool consistently failed to apply the changes. I have exhausted my attempts to make the tool work properly.

As I am running out of turns, I will now submit the current changes. I am unable to move to the next steps because I couldn't get the  to work.

- Paper drop🎓👨🏫! Please see our [ArxiV preprint](https://arxiv.org/abs/2303.00747) for benchmarking and details of WhisperX. We also introduce more efficient batch inference resulting in large-v2 with *60-70x REAL TIME speed.
<h2 align="left" id="setup">Setup ⚙️</h2>
Tested for PyTorch 2.0, Python 3.10 (use other versions at your own risk!)
### 1. Simple Installation (Recommended)
GPU execution requires the NVIDIA libraries cuBLAS 11.x and cuDNN 8.x to be installed on the system. Please refer to the [CTranslate2 documentation](https://opennmt.net/CTranslate2/installation.html).
The easiest way to install WhisperX is through PyPi:
### 1. Create Python3.10 environment
`conda create --name whisperx python=3.10`
`conda activate whisperx`
### 2. Install PyTorch, e.g. for Linux and Windows CUDA11.8:
`conda install pytorch==2.0.0 torchaudio==2.0.0 pytorch-cuda=11.8 -c pytorch -c nvidia`
See other methods [here.](https://pytorch.org/get-started/previous-versions/#v200)
### 3. Install WhisperX
You have several installation options:
#### Option A: Stable Release (recommended)
Install the latest stable version from PyPI:
```bash
pip install whisperx
```
Or if using [uvx](https://docs.astral.sh/uv/guides/tools/#running-tools):
#### Option B: Development Version
Install the latest development version directly from GitHub (may be unstable):
```bash
uvx whisperx
pip install git+https://github.com/m-bain/whisperx.git
```
### 2. Advanced Installation Options
These installation methods are for developers or users with specific needs. If you're not sure, stick with the simple installation above.
#### Option A: Install from GitHub
To install directly from the GitHub repository:
If already installed, update to the most recent commit:
```bash
uvx git+https://github.com/m-bain/whisperX.git
pip install git+https://github.com/m-bain/whisperx.git --upgrade
```
#### Option B: Developer Installation
If you want to modify the code or contribute to the project:
#### Option C: Development Mode
If you wish to modify the package, clone and install in editable mode:
```bash
git clone https://github.com/m-bain/whisperX.git
cd whisperX
uv sync --all-extras --dev
pip install -e .
```
> **Note**: The development version may contain experimental features and bugs. Use the stable PyPI release for production environments.
@ -104,12 +117,12 @@ uv sync --all-extras --dev
You may also need to install ffmpeg, rust etc. Follow openAI instructions here https://github.com/openai/whisper#setup.
### Speaker Diarization
To **enable Speaker Diarization**, include your Hugging Face access token (read) that you can generate from [Here](https://huggingface.co/settings/tokens) after the `--hf_token` argument and accept the user agreement for the following models: [Segmentation](https://huggingface.co/pyannote/segmentation-3.0) and [Speaker-Diarization-3.1](https://huggingface.co/pyannote/speaker-diarization-3.1) (if you choose to use Speaker-Diarization 2.x, follow requirements [here](https://huggingface.co/pyannote/speaker-diarization) instead.)
> **Note**<br>
> As of Oct 11, 2023, there is a known issue regarding slow performance with pyannote/Speaker-Diarization-3.0 in whisperX. It is due to dependency conflicts between faster-whisper and pyannote-audio 3.0.0. Please see [this issue](https://github.com/m-bain/whisperX/issues/499) for more details and potential workarounds.
