If I “pyddm.set_N_cpus (1)” rather than >1 after importing numpy, there won't be any problems

``` import pandas import numpy as np import pyddm import pyddm.plot from pyddm import Sample with open("roitman_rts.csv", "r") as f: df_rt = pandas.read_csv(f) pyddm.set_N_cpus(2) # if only 1, it works...

The most streamlined code is already above. It's just a small change to your example. I've also uploaded it to my [github repository.](https://github.com/[Hyphcha/pyddmerror](https://github.com/Hyphcha/pyddmerror))
