Value
class max.graph.Value(value: Value | Value | BufferValue | TensorValue | Shape | Dim | int | float | integer | floating | ndarray)
Represents a symbolic value within a Graph.
A Value can represent the output of a node, the arguments of a Graph (as seen from within its body), and more generally any symbolic value available within the Graph. Other nodes receive Value values as inputs to form a computation graph.
A Value may also refer to an existing input or output of a node, and you can change them, such as by swapping a new Value.
Conceptually, think of a Value as an edge in the dataflow graph, with the other end being the user of that value.
The following example shows how to work with Values in a graph to create a simple computation:
from max.graph import Graph, ops, Value
from max.dtype import DType
import numpy as np
with Graph("value_example") as graph:
# Create input values
a = ops.constant(np.array([1, 2, 3]), dtype=DType.float32)
b = ops.constant(np.array([4, 5, 6]), dtype=DType.float32)
# Use values to perform operations
c = a + b # c is a Value representing the addition
# Demonstrate that the result is a Value
print(f"Type of c: {type(c)}")
print(f"Is c a Value? {isinstance(c, Value)}")
from max.graph import Graph, ops, Value
from max.dtype import DType
import numpy as np
with Graph("value_example") as graph:
# Create input values
a = ops.constant(np.array([1, 2, 3]), dtype=DType.float32)
b = ops.constant(np.array([4, 5, 6]), dtype=DType.float32)
# Use values to perform operations
c = a + b # c is a Value representing the addition
# Demonstrate that the result is a Value
print(f"Type of c: {type(c)}")
print(f"Is c a Value? {isinstance(c, Value)}")
Similar to a regular variable, a Value has a data type.
buffer
property buffer*: BufferValue*
Returns the Value as a BufferValue.
Raises an exception if the Value is not a BufferValue.
opaque
property opaque*: _OpaqueValue*
Returns the Value as an _OpaqueValue.
Raises an exception if the Value is not a _OpaqueValue.
tensor
property tensor*: TensorValue*
Returns the Value as a TensorValue.
Raises an exception if the Value is not a TensorValue.
type
property type*: Type*
Returns the type of the Value as a Type.
