It seems that your sigpy version in the requirements.txt sigpy==0.1.14 is too old.
Therefore, some of the commands cannot run. For example, if I run the following command:

pdhg_app = mr.app.SenseRecon(
ksp, mps, coord=coord, max_iter=max_iter, lamda=lamda,
solver='PrimalDualHybridGradient', device=device, save_objective_values=True)

compiler will tell me that the keyword "solver" cannot be found.

What's the data type for the k space data?
Are those complex 64? Does it support complex 64 data type?

Hi Frank,
In your code, do you organize your k-space array as number of coil channels, number of repetitions, and number of readout points? The coordinate array has its shape arranged as number of repetitions, number of readout points and number of dimensions. Is that right?

How can we use your code for k space measurements in the ISMRM format? The k space measurements we have are arranged as "the number of columns, the number of spokes, and the number of coils ". How do we convert this format into your format?

Hi Frank, does your code support 3D reconstruction, or only 2D? It seems that all example datasets are 2D. Is that right? Do you have any 3D datasets for us to try?
