fanbeam operator receives an error NAN

[tavan95]

I installed the package according to the following commands

1. conda install tensorflow _gpu==1.12.0 python==3.6.7 cudatoolki=9 cundnn=7.6.5
2. pip install https://github.com/odlgroup/odl/archive/master.zip 3.pip install https://github.com/adler-j/adler/archive/master.zip 4.conda install astra_toolbox_c satra toolbox/label/dev 5.conda install spyder 6.conda install skim_image

I can run primal-dual program but when I run myo_learned_primal_dual randomly receive the error NAN.(I think the error depend on the operator Because when I change the operator in the learned_primal_dual file I get the same error as when I run the myo_learned_primal_dual program) in the issue of the primal_dual https://github.com/adler-j/learned_primal_dual/issues/9 say reinstall odl package I do this but received the error again.
