Error box Behnken

[bouhlelma]

Hi, I am using pyDOE for generating box Behnken and I got an error:
File "/root/anaconda3/lib/python3.6/site-packages/pyDOE/doe_repeat_center.py", line 43, in repeat_center
return np.zeros((repeat, n))
TypeError: 'float' object cannot be interpreted as an integer

I think the problem is in line 73 from the file pyDOE/doe_box_behnken:
nb_lines = (n*(n-1)/2)*H_fact.shape[0]

when I modify the above line to
nb_lines = int((n*(n-1)/2)*H_fact.shape[0])
it works well
