I would like to use odl to reconstruct the mayo datasets; I am trying to follow the scripts: https://github.com/odlgroup/odl/blob/25ec783954a85c2294ad5b76414f8c7c3cd2785d/odl/contrib/datasets/ct/examples/mayo_reconstruct.py https://github.com/odlgroup/odl/blob/25ec783954a85c2294ad5b76414f8c7c3cd2785d/odl/contrib/datasets/ct/mayo.py However the import statement fails: 8 from dicom.datadict import DicomDictionary,...
I just could not make correspondence between the math and implementation of PDHG. It seems that we do not need to compute gradient when update x  https://github.com/odlgroup/odl/blob/0b088df8dc4621c68b9414c3deff9127f4c4f11d/odl/solvers/nonsmooth/primal_dual_hybrid_gradient.py#L282

Hi! I am trying to run the jupyter notebook: part3_learned_reconstruction_pytorch.ipynb from the odlworkshop . I use pytorch 1.7.0 and cuda 10.1. I get the following error message: --------------------------------------------------------------------------- RuntimeError Traceback...
I want to create a helical geometry with cylindrical detector. Here is my code: reco_space = odl.uniform_discr(min_pt=[-63.5, -63.5, 0], max_pt=[63.5, 63.5, 14], shape=[128, 128, 15], dtype='float32') angle_partition = odl.uniform_partition(0, 2...
Hello, @adler-j . I tried to run the following code with ODL in ubuntu 16.04 with python3.6. The original geometry I find in your public code for Learned Primal Dual...

So I've been trying to reconstruct some tomo data that has negative values and while I get a pretty nice results with fbp, when I try to run either the...
Hello, I am trying to perform FISTA reconstruction but the f_prox = f.proximal(gamma) line in proximal_gradient_solvers.py throws me an error because (I guess) my regularizer functional f falls into the...
