tf.get_static_value

View source on GitHub

Returns the constant value of the given tensor, if efficiently calculable.

Aliases:

  • tf.compat.v1.get_static_value
  • tf.compat.v2.get_static_value
tf.get_static_value(
    tensor,
    partial=False
)

This function attempts to partially evaluate the given tensor, and returns its value as a numpy ndarray if this succeeds.

Compatibility(V1): If constant_value(tensor) returns a non-None result, it will no longer be possible to feed a different value for tensor. This allows the result of this function to influence the graph that is constructed, and permits static shape optimizations.

Args:

  • tensor: The Tensor to be evaluated.
  • partial: If True, the returned numpy array is allowed to have partially evaluated values. Values that can't be evaluated will be None.

Returns:

A numpy ndarray containing the constant value of the given tensor, or None if it cannot be calculated.

Raises:

  • TypeError: if tensor is not an ops.Tensor.
