Install

GSPICE installs from the Python Package Index (pygspice) or from a local Git clone and imports as gspice.

Requirements

GSPICE needs Python 3.11 or later, numpy 1.26 or later and scipy 1.11 or later. pip installs numpy and scipy if they are missing.

Install from PyPI

GSPICE is on the Python Package Index (PyPI) as pygspice. Its import name is gspice:

Shell

pip install pygspice

An install from GitHub made before 2026-10-29 is named gspice. If pip show gspice finds it, run pip uninstall gspice first, because both packages write the same files.

Install from a clone

A clone of the repository also holds the tests and the scripts of these pages. Clone it, then install it from its folder:

Shell

git clone https://github.com/joshspeagle/GSPICE
cd GSPICE
pip install .

Check the installation

Print the version of GSPICE:

Shell

python -c "import gspice; print(gspice.__version__)"

Text

2.0.0

If Python prints ModuleNotFoundError: No module named 'gspice', pip installed GSPICE for another Python. Run python -m pip install instead of pip install, with the python that you use.
