🤗 Tokenizers is tested on Python 3.5+.

You should install 🤗 Tokenizers in a virtual environment. If you’re unfamiliar with Python virtual environments, check out the user guide. Create a virtual environment with the version of Python you’re going to use and activate it.

Installation with pip

🤗 Tokenizers can be installed using pip as follows:

pip install tokenizers

Installation from sources

To use this method, you need to have the Rust language installed. You can follow the official guide for more information.

If you are using a unix based OS, the installation should be as simple as running:

curl --proto '=https' --tlsv1.2 -sSf | sh

Or you can easiy update it with the following command:

rustup update

Once rust is installed, we can start retrieving the sources for 🤗 Tokenizers:

git clone

Then we go into the python bindings folder:

cd tokenizers/bindings/python

At this point you should have your virtual environment already activated. In order to compile 🤗 Tokenizers, you need to install the Python package setuptools_rust:

pip install setuptools_rust

Then you can have 🤗 Tokenizers compiled and installed in your virtual environment with the following command:

python install
