Installation

Installation is as simple as:

pip install pydantic

uv add pydantic

Pydantic has a few dependencies:

• pydantic-core: Core validation logic for Pydantic written in Rust.
• typing-extensions: Backport of the standard library typing module.
• annotated-types: Reusable constraint types to use with typing.Annotated.
• typing-inspection: Runtime typing introspection tools.

If you've got Python 3.10+ and pip installed, you're good to go.

Pydantic is also available on conda under the conda-forge channel:

conda install pydantic -c conda-forge

Pydantic has the following optional dependencies:

• email: Email validation provided by the email-validator package.
• timezone: Fallback IANA time zone database provided by the tzdata package.

To install optional dependencies along with Pydantic:

# with the `email` extra:
pip install 'pydantic[email]'
# or with `email` and `timezone` extras:
pip install 'pydantic[email,timezone]'

# with the `email` extra:
uv add 'pydantic[email]'
# or with `email` and `timezone` extras:
uv add 'pydantic[email,timezone]'

Of course, you can also install requirements manually with pip install email-validator tzdata.

And if you prefer to install Pydantic directly from the repository:

pip install 'git+https://github.com/pydantic/pydantic@main'
# or with `email` and `timezone` extras:
pip install 'git+https://github.com/pydantic/pydantic@main#egg=pydantic[email,timezone]'

uv add 'git+https://github.com/pydantic/pydantic@main'
# or with `email` and `timezone` extras:
uv add 'git+https://github.com/pydantic/pydantic@main#egg=pydantic[email,timezone]'
