Versioned name: ReadValue-3
Category: Infrastructure
Short description: ReadValue returns value of the variable_id
variable.
Detailed description:
ReadValue returns value from the corresponding variable_id
variable if the variable was set already by Assign operation and was not reset.
The operation checks that the type and shape of the output are the same as
declared in variable_id
and returns an error otherwise. If the corresponding variable was not set or was reset,
the operation returns the value from the 1 input, and initializes the variable_id
shape and type
with the shape and type from the 1 input.
Attributes:

Description: identifier of the variable to be read
Range of values: any non-empty string
Type: string
Required: yes
Inputs
1:
init_value
- input tensor with constant values of any supported type. Required.
Outputs
1: tensor with the same shape and type as
init_value
.
