Log#
Log - 13#
Version
name: Log (GitHub)
domain: main
since_version: 13
function: False
support_level: SupportType.COMMON
shape inference: True
This version of the operator has been available since version 13.
Summary
Calculates the natural log of the given input tensor, element-wise.
Inputs
input (heterogeneous) - T: Input tensor
Outputs
output (heterogeneous) - T: The natural log of the input tensor computed element-wise
Type Constraints
T in ( tensor(bfloat16), tensor(double), tensor(float), tensor(float16) ): Constrain input and output types to float tensors.
Examples
default
import numpy as np
import onnx
node = onnx.helper.make_node(
"Log",
inputs=["x"],
outputs=["y"],
)
x = np.array([1, 10]).astype(np.float32)
y = np.log(x) # expected output [0., 2.30258512]
expect(node, inputs=[x], outputs=[y], name="test_log_example")
x = np.exp(np.random.randn(3, 4, 5).astype(np.float32))
y = np.log(x)
expect(node, inputs=[x], outputs=[y], name="test_log")
