PtyPy 1 is a framework for scientific ptychography compiled by P.Thibault and B. Enders and licensed under the GPLv2 license.
It comprises 8 years of experience in the field of ptychography condensed to a versatile python package. The package covers the whole path of ptychographic analysis after the actual experiment - from data management to reconstruction to visualization.
The main idea of ptypy is: “Flexibility and Scalabality through abstraction”.
Most often, you will find a class for every concept of ptychography in
PtyPy. Using these or other more abstract base classes, new ideas
may be developed in a rapid manner without the cumbersome overhead of
, memory access or
distributed computing. Additionally, PtyPy
provides a rich set of
utilities and helper functions,

Maximum Likelihood 3 engine with preconditioners and regularizers.
A few more engines (RAAR, sDR, ePIE, …).
Fully parallelized using the Massage Passing Interface (MPI). Simply execute your script with:
$ mpiexec/mpirun -n [nodes] python <your_ptypy_script>.py
GPU acceleration based on custom kernels, pycuda, and reikna.
A client-server approach for visualization and control based on ZeroMQ . The reconstruction may run on a remote hpc cluster while your desktop computer displays the reconstruction progress.
Mixed-state reconstructions of probe and object 2 for overcoming partial coherence or related phenomena.
On-the-fly reconstructions (while data is being acquired) using the the
