tf.VariableScope

tf.VariableScope

class tf.VariableScope

Defined in tensorflow/python/ops/variable_scope.py.

See the guide: Variables > Sharing Variables

Variable scope object to carry defaults to provide to get_variable.

Many of the arguments we need for get_variable in a variable store are most easily handled with a context. This object is used for the defaults.

Attributes:

• name: name of the current scope, used as prefix in get_variable.
• initializer: default initializer passed to get_variable.
• regularizer: default regularizer passed to get_variable.
• reuse: Boolean or None, setting the reuse in get_variable.
• caching_device: string, callable, or None: the caching device passed to get_variable.
• partitioner: callable or None: the partitioner passed to get_variable.
• custom_getter: default custom getter passed to get_variable.
• name_scope: The name passed to tf.name_scope.
• dtype: default type passed to get_variable (defaults to DT_FLOAT).
• use_resource: if False, create a normal Variable; if True create an experimental ResourceVariable with well-defined semantics. Defaults to False (will later change to True).
