Windows load error

[ccjalal]

I get the following error on trying to run from windows and python 3.

Traceback (most recent call last):
File "cube_interactive.py", line 46, in
class Cube:
File "cube_interactive.py", line 77, in Cube
for theta in (np.pi / 2, -np.pi / 2)]
File "cube_interactive.py", line 77, in
for theta in (np.pi / 2, -np.pi / 2)]
NameError: name 'x' is not defined

The only thing I know how to do is shine the @jakevdp symbol.

That's quite strange because x is defined on line 76, right above where the error says it's undefined.

I found out that the code worked with 2.7 but had the issue with Python 3.6. Have you guys solved the problem?

Solved. The issue occurred due to the difference between Python 2 and 3.

Solution:
File "cube_interactive.py", lines 76-79

rots = [Quaternion.from_v_theta(x, theta)
        for theta in (np.pi / 2, -np.pi / 2)]
rots += [Quaternion.from_v_theta(y, theta)
         for theta in (np.pi / 2, -np.pi / 2, np.pi, 2 * np.pi)]

=>
rots = [Quaternion.from_v_theta(x, np.pi / 2)]
rots += [Quaternion.from_v_theta(x, -np.pi / 2)]

for theta in (np.pi / 2, -np.pi / 2, np.pi, 2 * np.pi):
    rots += [Quaternion.from_v_theta(y, theta)]
