Acosh#
Acosh - 9#
Version
name: Acosh (GitHub)
domain: main
since_version: 9
function: False
support_level: SupportType.COMMON
shape inference: True
This version of the operator has been available since version 9.
Summary
Calculates the hyperbolic arccosine of the given input tensor element-wise.
Inputs
input (heterogeneous) - T: Input tensor
Outputs
output (heterogeneous) - T: The hyperbolic arccosine values of the input tensor computed element-wise
Type Constraints
T in ( 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(
"Acosh",
inputs=["x"],
outputs=["y"],
)
x = np.array([10, np.e, 1]).astype(np.float32)
y = np.arccosh(x) # expected output [2.99322295, 1.65745449, 0.]
expect(node, inputs=[x], outputs=[y], name="test_acosh_example")
x = np.random.uniform(1.0, 10.0, (3, 4, 5)).astype(np.float32)
y = np.arccosh(x)
expect(node, inputs=[x], outputs=[y], name="test_acosh")
