np.array question

[hissonrr]

Morning all,

I am a python beginner and was playing around.

I ran into a roadblock when the original np.array was set up to use a 9 varriable array like below...

adjacent_facies = np.array([[1], [0,2], [1], [4], [3,5], [4,6,7], [5,7], [5,6,8], [6,7]])

and I need to convert it for a 6 variable breakdown and get an index error...

IndexError: index 6 is out of bounds for axis 0 with size 6

Any help would be appreciated as I do not really understand the np.array functionality fully yet.

Thanks,

-RH
