Hi Eun-Suk,
Did you do
python -m pip install
https://millenia.cars.aps.anl.gov/xraylarch/downloads/xraylarch-latest-py3-none-any.whl
?
That will install the development version (later than 0.9.74, not yet
0.9.75, sorry for that delay). This works for me:
from larch.xafs import feffpath
p1 = feffpath('feff0001.dat', e0=-1, sigma2=0.010)
p1.s02 = 0.95
dat = ff2chi([p1])
I don't know of any multiprocessing problem...
Cheers,
