Hello Matt
Thank you for your kindness.
I simplified the ff2chi problem in multiprocessing. I found that the ff2chi
problem in multiprocessing is caused by receiving the arguments in an
object (TestClass).
For instance
The below code works in multiprocessing
---------------------------------------------
class TestClass():
def __init__(self, out_path_lists):
self.path_lists=out_path_lists
def test(self):
path1 = feffpath(os.path.join(dPath,'FEFF1', fname1))
path_lists=[path1]
theory_sum=Group(label='theory_group_sum')
ff2chi(path_lists, group=theory_sum)
new_state=theory_sum.ch
However, If I change ff2chi(path_lists, group=theory_sum) to*
ff2chi(self.path_lists, group=theory_sum*), the ff2chi problem is caused.
Finally, I want to use multiprocessing. The xraylarch you sent does not
work in multiprocessing.
If you are possible, please send me larch 0.9.71 to reinstall
