spyrit 2.2.0

Demo package

SPyRiT

SPyRiT is a PyTorch-based toolbox for deep image reconstruction. While SPyRiT was originally designed for single-pixel image reconstruction, it can solve any linear reconstruction problem.

Installation

The spyrit package is available for Linux, MacOs and Windows. We recommend to use a virtual environment.

Linux and MacOs

(user mode)

pip install spyrit

(developper mode)

git clone https://github.com/openspyrit/spyrit.git
cd spyrit
pip install -e .

Windows

On Windows you may need to install PyTorch first. It may also be necessary to run the following commands using administrator rights (e.g., starting your Python environment with administrator rights).

Adapt the two examples below to your configuration (see here for the latest instructions)

(CPU version using pip)

pip3 install torch torchvision torchaudio

(GPU version using conda)

conda install pytorch torchvision torchaudio pytorch-cuda=11.8 -c pytorch -c nvidia

Then, install SPyRiT using pip.

Test

To check the installation, run in your python terminal:

import spyrit

Examples

To start, check the documentation tutorials.

More advanced reconstruction examples can be found in spyrit-examples/tutorial. Run advanced tutorial in colab:
