The matrix's second dimension(row length) is as same as the original last

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)].
