RuntimeError: generator raised StopIteration

Hi I am learning to use this program, however, when running the lorenz.py example I get this error:

Traceback

File "C:\Users\81599\Documents\Python Scripts\Evolutionary Algorithms\Genetic Programming\Glyph\glyph-master\examples\control\control_problem.py", line 58, in odeint raise StopIteration

StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

thanks in advance

Thanks for the Bug report.

This should be fixed with #68. Can you please try again using the current master branch?
