- Multi-processing and multi-gpu to deterministic atlas and longitudinal atlas models

- Dependencies update (Pytorch 1.0, Pykeops 1.0, ...)

- VTK reader

- Python 3.7 compliant

- Added the MCMC-SAEM estimator along with the longitudinal atlas model

- Bug fixes

The full CHANGELOG can be found on our gitlab repository.

New Gitlab.com repository

As you might have noticed from the link above, we have migrated our repository to Gitlab.com. This implies a small change to your git remote if you have cloned the repository. 

You may update your git remotes by using the following command: 

git remote set-url origin git@gitlab.com:icm-institute/aramislab/deformetrica.git

You can check that the previous command has been effectively applied by running:

git remote-v

Try the API online !

An online Python notebook is now available on Google colab. This enables anyone to try out Deformetrica's python API directly within a online Python notebook without having to install anything on your computer ! A little bonus is that GPU acceleration is available using Nvidia Tesla K80 cards ! Keep in mind that long running instances can by shutdown by Google. This should only be used for testing.

Documentation

Our documentation has been updated. You can view the wiki here.

Dear Deformetrica Group,

Thank you for your great software.

I am trying to use the latest version of deformetrica on a cluster. When I use a keops kernel, I always get a segmentation fault error, the torch kernel works great. I would appreciate it if you can give me some hints about what the problem could be.

Best,

Amanda

Hello Amanda,

Thank you for using Deformetrica !

It is indeed unfortunate that you are experiencing issues while using the keops kernel.

Could you give me more information about your configuration ? 

Please keep in mind that the keops kernel requires a few extra dependencies used to compile. Could you check that CMake, cuda a C++ compiler (g++) is installed ?

Bests,

Benoit
