You should install 🤗 Tokenizers in a
4
`virtual environment <https://docs.python.org/3/library/venv.html>`_. If you're unfamiliar with
5
Python virtual environments, check out the
6
`user guide <https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/>`__.

Create a virtual environment with the version of Python you're going to use and activate it.

20
To use this method, you need to have the Rust language installed. You can follow
21
`the official guide <https://www.rust-lang.org/learn/get-started>`__ for more information.

23
If you are using a unix based OS, the installation should be as simple as running::
24

25
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
26

27
Or you can easiy update it with the following command::
28

29
    rustup update
30

31
Once rust is installed, we can start retrieving the sources for 🤗 Tokenizers::
32

33
    git clone https://github.com/huggingface/tokenizers
34

35
Then we go into the python bindings folder::
36

37
    cd tokenizers/bindings/python
38

39
At this point you should have your `virtual environment`_ already activated. In order to
40
compile 🤗 Tokenizers, you need to::
41

42
    pip install -e .
