See the guide: Framework (contrib) > Variables
Gets an existing model variable with these parameters or creates a new one.
name: the name of the new or existing variable.
shape: shape of the new or existing variable.
dtype: type of the new or existing variable (defaults to
initializer: initializer for the variable if one is created.
regularizer: a (Tensor -> Tensor or None) function; the result of applying it on a newly created variable will be added to the collection GraphKeys.REGULARIZATION_LOSSES and can be used for regularization.
Truealso add the variable to the graph collection
collections: A list of collection names to which the Variable will be added. Note that the variable is always also added to the
caching_device: Optional device string or function describing where the Variable should be cached for reading. Defaults to the Variable's device.
device: Optional device to place the variable. It can be an string or a function that is called to get the device for the variable.
partitioner: Optional callable that accepts a fully defined
TensorShapeand dtype of the
Variableto be created, and returns a list of partitions for each axis (currently only one axis can be partitioned).
custom_getter: Callable that allows overwriting the internal get_variable method and has to have the same signature.
Trueuse a ResourceVariable instead of a Variable.
The created or existing variable.
