Not converge when I tried "test_sparse_multislice_ptycho.py"

[ben-mengz]

I'm trying to test the "test_sparse_multislice_ptycho.p.". However, the file path '../demos/sparse_multislice_ptycho' doesn't really exist. So I tried to search the file name for the 'date.h5', which is in path '../demos/siemens_star_aps_2idd'.
It seems to be the correct one. However, the algorithm didn't converge when I tried it. Somehow the error always goes back to the same as the first epoch after each epoch.
