BrokenPipeError: [Errno 32] Broken pipe

I try to run the example code in Module usage 2D.ipynb or Module usage 3D.ipynb. When I get to the calc_gamma line, I get the following error:

File "", line 1, in gamma = calc_gamma(coords_reference, dose_reference,coords_evaluation, dose_evaluation, distance_threshold, dose_threshold, lower_dose_cutoff=lower_dose_cutoff, distance_step_size=distance_step_size, maximum_test_distance=maximum_test_distance, max_concurrent_calc_points=max_concurrent_calc_points, num_threads=num_threads)

File "C:\ProgramData\Anaconda3\lib\site-packages\npgamma__init__.py", line 324, in calc_gamma np.nan * np.ones_like(dose_evaluation_flat))).start()

Got it to work by adding

if name == 'main':

before the gamma = calc_gamma line

Good to hear :)
