Hi!
I have encountered this error:
'numpy.ndarray' object has no attribute 'contiguous'

in this code:
a=numpy.array([[1,2,3,4],[5,6,7,8],[1,2,3,4],[5,6,7,8]])
dct.dct_2d(a)

that the dct func contains:
x_shape = x.shape
N = x_shape[-1]
x = x.contiguous().view(-1, N)

Could you mind helping me solve this?
