Instantiates a variable and returns it.
k_variable(value, dtype = NULL, name = NULL, constraint = NULL)
Numpy array, initial value of the tensor.
Optional name string for the tensor.
Optional projection function to be applied to the variable after an optimizer update.
A variable instance (with Keras metadata included).
This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
