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.
Pydantic is also available on conda under the conda-forge channel:
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
Settings
requires python-dotenv
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 pip install
.
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]
