CrossEntropy Operator.
The input 'X' and 'Label' will first be logically flattened to 2-D matrixs.
The matrix's second dimension(row length) is as same as the original last
dimension, and the first dimension(column length) is the product of all other
original dimensions. Then the softmax computation will take palce on each raw
of flattened matrixs.
It supports both standard cross-entropy and soft-label cross-entropy loss

**Flatten layer**
Flattens the input tensor into a 2D matrix.
Examples:
Case 1:
Given
X.shape = (3, 100, 100, 4)
and
axis = 2
We get:
Out.shape = (3 * 100, 4 * 100)
Case 2:
Given
X.shape = (3, 100, 100, 4)
and
axis = 0
We get:
Out.shape = (1, 3 * 100 * 100 * 4)
Args:
x (Variable): A tensor of rank >= axis.
axis (int): Indicate up to which input dimensions (exclusive) should
be flattened to the outer dimension of the output.
The value for axis must be in the range [0, R], where R
is the rank of the input tensor. When axis = 0, the shape
of the output tensor is (1, (d_0 X d_1 ... d_n), where the
shape of the input tensor is (d_0, d_1, ... d_n).
name(str|None): A name for this layer(optional). If set None, the layer
will be named automatically.
Returns:
Variable: A 2D tensor with the contents of the input tensor, with input
dimensions up to axis flattened to the outer dimension of
the output and remaining input dimensions flattened into the
inner dimension of the output.
Raises:
ValueError: If x is not a variable.
ValueError: If axis is not in range [0, rank(x)].
Examples:
