image.TextureGrid error when given an ImageGrid

[Nicky Mac]

I am attempting to draw a Skybox from an existing file with the following code:

    boxname = 'skybox1.jpg'   

    print('Loading',boxname)

    skygrid = image.load(os.path.join('Assets', boxname))

    sky_grid = image.ImageGrid(skygrid, 3,4)

    sky = image.TextureGrid(sky_grid) # resource KeyError: <TextureRegion 64x64>

    sky_frames = [sky[4], sky[6], sky[9], sky[1], sky[7], sky[5]]

------------------------------ here's what happens: ----------------------------------------

Loaded skybox1.jpg

Traceback (most recent call last):

  File "C:\Python\Python36\lib\site-packages\pyglet\resource.py", line 435, in file

    location = self._index[name]

KeyError: <TextureRegion 64x64>

TextureImage  is erroneously trying to use resource to read theTextureRegion as if it were a file

I'm on Python 36.
