If you are using pip, you can simply run

pip install symfit

from your terminal. If you are using linux and do not use pip, you can download the source from and install manually.

Are you not on linux and you do not use pip? That’s your own mess.

Contrib module

To also install the dependencies of 3rd party contrib modules such as interactive guesses, install symfit using:

pip install symfit[contrib]


pip install sympy
pip install numpy
pip install scipy
