Variable and Parameter¶

Variable classes and utilities¶

`chainer.Variable`	Array with a structure to keep track of computation.
`chainer.as_variable`	Converts an array or a variable into `Variable`.
`chainer.Parameter`	Parameter variable that can be registered to a link.
`chainer.variable.VariableNode`	Node in the backward computational graph representing a variable.

N-dimensional array¶

chainer.Variable holds its value as an n-dimensional array (ndarray). Chainer supports the following classes:

numpy.ndarray, including ideep4py.mdarray
cupy.ndarray

Note

Python scalars (float, etc.) and NumPy scalars (numpy.float16, numpy.float32, etc.) cannot be used as chainer.Variable.array. See also chainer.utils.force_array().
