Installation is as simple as:
pip install pydantic
pydantic has no required dependencies except python 3.6, 3.7, 3.8, or 3.9,
typing-extensions, and the
dataclasses backport package for python 3.6.
If you've got python 3.6+ and
pip installed, you're good to go.
conda install pydantic -c conda-forge
pydantic can optionally be compiled with cython which should give a 30-50% performance improvement.
Binaries are available from PyPI for Linux, MacOS and 64bit Windows.
If you're installing manually, install
cython before installing pydantic and compilation should happen automatically.
To test if pydantic is compiled run:
import pydantic print('compiled:', pydantic.compiled)
pydantic has three optional dependencies:
- If you require email validation you can add email-validator
- dotenv file support with
To install these along with pydantic:
pip install pydantic[email] # or pip install pydantic[dotenv] # or just pip install pydantic[email,dotenv]
Of course, you can also install these requirements manually with
pip install email-validator and/or
And if you prefer to install pydantic directly from the repository:
pip install git+git://github.com/samuelcolvin/pydantic@master#egg=pydantic # or with extras pip install git+git://github.com/samuelcolvin/pydantic@master#egg=pydantic[email,dotenv]
