After trging to calculate sigma values from the tutorial example I encountered a syntax error with gaussian function:
File "g_fit.py", line 193
def gaussian((x,y,z),c_x,c_y,c_z,sigma):
^
SyntaxError: invalid syntax
I've tried it with python3.5, 3.6, 3.9 with no luck. With python2.x, on the other hand, does not understand numpy. What can I do to overcome this issue?
