type error when using MGC.p_value() on longs

[tathey1]

Describe the bug
data type error when using MGC.p_value() on long type

To Reproduce
from mgcpy.independence_tests.mgc import MGC
a = np.array([[1.,1.],[1.,1.]])
b = np.array([[2.,2.],[2.,2.]])
mgc.p_value(a,b)
Expected behavior
I expected this to work.

Error output

Did you find a solution ? I have the same error ...

[shiyussy]

I have the same error.
I think that may be caused by that it has to do with how python interprets types, and how C interprets types when using Cython.

I've fixed this and should be in the next release

Since you are using Windows 10, I think you might also need to install a compiler for Cython. I can update these instructions in the ReadMe. Instructions for this can be found here: https://wiki.python.org/moin/WindowsCompilers
