mindspore.nn.Tanh
- class mindspore.nn.Tanh[source]
Tanh activation function.
Applies the Tanh function element-wise, returns a new tensor with the hyperbolic tangent of the elements of input, The input is a Tensor with any valid shape.
Tanh function is defined as:
where
is an element of the input Tensor.- Inputs:
input_data (Tensor) - The input of Tanh with data type of float16 or float32.
- Outputs:
Tensor, with the same type and shape as the input_data.
- Raises
TypeError – If dtype of input_data is neither float16 nor float32.
- Supported Platforms:
Ascend
GPU
CPU
Examples
>>> input_x = Tensor(np.array([1, 2, 3, 2, 1]), mindspore.float16) >>> tanh = nn.Tanh() >>> output = tanh(input_x) >>> print(output) [0.7617 0.964 0.995 0.964 0.7617]
