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...
