# Installation Install Diffusers for with PyTorch. Support for other libraries will come in the future 🤗 Diffusers is tested on Python 3.7+, and PyTorch 1.7.0+. ## Install with pip You should install 🤗 Diffusers in a [virtual environment](https://docs.python.org/3/library/venv.html). If you're unfamiliar with Python virtual environments, take a look at this [guide](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/). A virtual environment makes it easier to manage different projects, and avoid compatibility issues between dependencies. Start by creating a virtual environment in your project directory: ```bash python -m venv .env ``` Activate the virtual environment: ```bash source .env/bin/activate ``` Now you're ready to install 🤗 Diffusers with the following command: ```bash pip install diffusers ``` ## Install from source Install 🤗 Diffusers from source with the following command: ```bash 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](https://github.com/huggingface/transformers/issues), 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: ```bash git clone https://github.com/huggingface/diffusers.git cd diffusers pip install -e . ``` 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/python3.7/site-packages/`, Python will also search the folder you cloned to: `~/diffusers/`. 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: ```bash cd ~/diffusers/ git pull ``` Your Python environment will find the `main` version of 🤗 Diffusers on the next run.
