# Installation Diffusers is tested on Python 3.8+ and PyTorch 1.4+. Install [PyTorch](https://pytorch.org/get-started/locally/) according to your system and setup. Create a [virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/) for easier management of separate projects and to avoid compatibility issues between dependencies. Use [uv](https://docs.astral.sh/uv/), a Rust-based Python package and project manager, to create a virtual environment and install Diffusers. ```bash uv venv my-env source my-env/bin/activate ``` Install Diffusers with one of the following methods. PyTorch only supports Python 3.8 - 3.11 on Windows. ```bash uv pip install diffusers["torch"] transformers ``` ```bash conda install -c conda-forge diffusers ``` A source install installs the `main` version instead of the latest `stable` version. The `main` version is useful for staying updated with the latest changes but it may not always be stable. If you run into a problem, open an [Issue](https://github.com/huggingface/diffusers/issues/new/choose) and we will try to resolve it as soon as possible. Make sure [Accelerate](https://huggingface.co/docs/accelerate/index) is installed. ```bash uv pip install accelerate ``` Install Diffusers from source with the command below. ```bash uv pip install git+https://github.com/huggingface/diffusers ``` ## Editable install An editable install is recommended for development workflows or if you're using the `main` version of the source code. A special link is created between the cloned repository and the Python library paths. This avoids reinstalling a package after every change. Clone the repository and install Diffusers with the following commands. ```bash git clone https://github.com/huggingface/diffusers.git cd diffusers uv pip install -e ".[torch]" ``` > [!WARNING] > You must keep the `diffusers` folder if you want to keep using the library with the editable install. Update your cloned repository to the latest version of Diffusers with the command below. ```bash cd ~/diffusers/ git pull ``` ## Cache Model weights and files are downloaded from the Hub to a cache, which is usually your home directory. Change the cache location with the [HF_HOME](https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables#hfhome) or [HF_HUB_CACHE](https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables#hfhubcache) environment variables or configuring the `cache_dir` parameter in methods like [`~DiffusionPipeline.from_pretrained`]. ```bash export HF_HOME="/path/to/your/cache" export HF_HUB_CACHE="/path/to/your/hub/cache" ``` ```py from diffusers import DiffusionPipeline pipeline = DiffusionPipeline.from_pretrained( "black-forest-labs/FLUX.1-dev", cache_dir="/path/to/your/cache" ) ``` Cached files allow you to use Diffusers offline. Set the [HF_HUB_OFFLINE](https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables#hfhuboffline) environment variable to `1` to prevent Diffusers from connecting to the internet. ```shell export HF_HUB_OFFLINE=1 ``` For more details about managing and cleaning the cache, take a look at the [Understand caching](https://huggingface.co/docs/huggingface_hub/guides/manage-cache) guide. ## Telemetry logging Diffusers gathers telemetry information during [`~DiffusionPipeline.from_pretrained`] requests. The data gathered includes the Diffusers and PyTorch version, the requested model or pipeline class, and the path to a pretrained checkpoint if it is hosted on the 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. Opt-out and disable telemetry collection with the [HF_HUB_DISABLE_TELEMETRY](https://huggingface.co/docs/huggingface_hub/package_reference/environment_variables#hfhubdisabletelemetry) environment variable. ```bash export HF_HUB_DISABLE_TELEMETRY=1 ``` ```bash set HF_HUB_DISABLE_TELEMETRY=1 ```
