Cannot "import colour" with Python 2.7.12 64-bit.

[Kunkka1988]

Hi KelSolaar,

I got a trouble with colour-science.
The colour-0.3.10.zip had been downloaded and installed, but when I tried to "import colour" on python 2.7.12 64-bit that will be failed.
If I use the 32-bit python then it will be fine, but I need the 64-bit python to work.

Here are the hints:
...

import colour
Traceback (most recent call last):
File "", line 1, in
File "C:\Python27\lib\site-packages\colour_science-0.3.10-py2.7.egg\colour_init_.py", line 41, in

File "C:\Python27\lib\site-packages\scipy_lib_ccallback.py", line 1, in
from . import _ccallback_c
ImportError: DLL load failed: %1 is not a valid Win32 application.
...

Could you have a look at this issue if free?
Thanks.

@Kunkka1988 : It seems like you have an installation issue with Scipy and this is not a Colour issue but a broad one in regard to your Python installation:

File "C:\Python27\lib\site-packages\scipy_lib_ccallback.py", line 1, in 
from . import _ccallback_c
ImportError: DLL load failed: %1 is not a valid Win32 application.

Scipy has compiled libraries and it seems like you are trying to load one that has architecture mismatch with the Python interpreter you are intended to use it with.

Please double check that both your Numpy and Scipy versions are compliant with your interpreter. You can directly import a Numpy and Scipy module at Python prompt to check they are working:

import numpy
import scipy.interpolate

Hi KelSolaar,

It works well after reinstall scipy-0.19.1-cp27-cp27m-win_amd64.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy.
Thank you so much:)

You are welcome @Kunkka1988! :)

I solved it by copying the module colour.py from the python2 directory to the python3 directory? took me weeks of trying things out to fix it

'''
sudo cp /usr/local/lib/python2.7/dist-packages/colour.py /usr/local/lib/python3.7/dist-packages/colour.py
'''

Hi @dtbulmerJRs,

You should avoid installing anything in your system Python environment, prefer a Virtual Environment ideally.

Cheers,
