Installation

🤗 Diffusers is tested on Python 3.8+, PyTorch 1.7.0+, and Flax. Follow the installation instructions below for the deep learning library you are using:

- PyTorch installation instructions
- Flax installation instructions

##
Install with pip

You should install 🤗 Diffusers in a virtual environment. If you’re unfamiliar with Python virtual environments, take a look at this guide. A virtual environment makes it easier to manage different projects and avoid compatibility issues between dependencies.

Create a virtual environment with Python or uv (refer to Installation for installation instructions), a fast Rust-based Python package and project manager.

uv
Python

    uv venv my-env
    source my-env/bin/activate

You should also install 🤗 Transformers because 🤗 Diffusers relies on its models.

Pytorch
Hide Pytorch content

PyTorch only supports Python 3.8 - 3.11 on Windows. Install Diffusers with uv.

    uv install diffusers["torch"] transformers

You can also install Diffusers with pip.

    pip install diffusers["torch"] transformers

JAX
Hide JAX content

Install Diffusers with uv.

    uv pip install diffusers["flax"] transformers

You can also install Diffusers with pip.

    pip install diffusers["flax"] transformers

##
Install with conda

After activating your virtual environment, with `conda` (maintained by the community):

    conda install -c conda-forge diffusers

##
Install from source

Before installing 🤗 Diffusers from source, make sure you have PyTorch and 🤗 Accelerate installed.

To install 🤗 Accelerate:

    pip install accelerate

Then install 🤗 Diffusers from source:

    pip install git+https://github.com/huggingface/diffusers

This command installs the bleeding edge `main` version rather than the latest `stable` version. The `main` version is useful for staying up-to-date with the latest developments. For instance, if a bug has been fixed since the last official release but a new release hasn’t been rolled out yet. However, this means the `main` version may not always be stable. We strive to keep the `main` version operational, and most issues are usually resolved within a few hours or a day. If you run into a problem, please open an Issue so we can fix it even sooner!

##
Editable install

You will need an editable install if you’d like to:

- Use the `main` version of the source code.
- Contribute to 🤗 Diffusers and need to test changes in the code.

Clone the repository and install 🤗 Diffusers with the following commands:

    git clone https://github.com/huggingface/diffusers.git
    cd diffusers

Pytorch
Hide Pytorch content

    pip install -e ".[torch]"

JAX
Hide JAX content

    pip install -e ".[flax]"

These commands will link the folder you cloned the repository to and your Python library paths. Python will now look inside the folder you cloned to in addition to the normal library paths. For example, if your Python packages are typically installed in `~/anaconda3/envs/main/lib/python3.10/site-packages/`, Python will also search the `~/diffusers/` folder you cloned to.

You must keep the `diffusers` folder if you want to keep using the library.

Now you can easily update your clone to the latest version of 🤗 Diffusers with the following command:

    cd ~/diffusers/
    git pull

Your Python environment will find the `main` version of 🤗 Diffusers on the next run.

##
Cache

Model weights and files are downloaded from the Hub to a cache which is usually your home directory. You can change the cache location by specifying the `HF_HOME` or `HUGGINFACE_HUB_CACHE` environment variables or configuring the `cache_dir` parameter in methods like from_pretrained().

Cached files allow you to run 🤗 Diffusers offline. To prevent 🤗 Diffusers from connecting to the internet, set the `HF_HUB_OFFLINE` environment variable to `1` and 🤗 Diffusers will only load previously downloaded files in the cache.

    export HF_HUB_OFFLINE=1

For more details about managing and cleaning the cache, take a look at the caching guide.

##
Telemetry logging

Our library gathers telemetry information during from_pretrained() requests. The data gathered includes the version of 🤗 Diffusers and PyTorch/Flax, the requested model or pipeline class, and the path to a pretrained checkpoint if it is hosted on the Hugging Face Hub. This usage data helps us debug issues and prioritize new features. Telemetry is only sent when loading models and pipelines from the Hub, and it is not collected if you’re loading local files.

We understand that not everyone wants to share additional information,and we respect your privacy. You can disable telemetry collection by setting the `HF_HUB_DISABLE_TELEMETRY` environment variable from your terminal:

On Linux/MacOS:

    export HF_HUB_DISABLE_TELEMETRY=1

On Windows:

    set HF_HUB_DISABLE_TELEMETRY=1
