I get the following error when I try to combine LUTs

lut = LUT.FromCubeFile("C:/Users/Junnu/Desktop/LUT1.cube")
lut2 = LUT.FromCubeFile("C:/Users/Junnu/Desktop/LUT2.cube")
lut3 = lut.CombineWithLUT(lut2)

Traceback (most recent call last):

Here are the cube LUT files I used

I was getting pylut 1.4.9 via pycharm venv, and works under python 3.6.5.
I have converted old print and xrange statements to python 3 version.

It seems that all of the From and To methods suffer from improper indices now, where they should be floored but was left as float. Since numpy no longer support float indices, I guess encapsulating with a int() will solve the problem.

Also I was trying this module with photoshop original LUTs, some nuke3DL file has entries that goes up to 12-bit color depth, but the first row ends with 1023, which by the FromNuke3DLFile() method should imply 10-bit depth and will lead to a lattice being 4 times brighter than the file was originally intended.
I think the correct outputDepth should actually be +2, but am not sure whether it is a common problem or not.

Fails with python-3 (current latest pypi version 1.4.9)

even i have installed in the environment, but it gives the error 'name pylut is not defined'
