mindspore.ops.Log

class mindspore.ops.Log(*args, **kwargs)[source]

Returns the natural logarithm of a tensor element-wise.

\[y_i = log_e(x_i)\]

Inputs:

input_x (Tensor) - The input tensor. The value must be greater than 0.

Outputs:

Tensor, has the same shape as the input_x.

Raises: TypeError – If input_x is not a Tensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> input_x = Tensor(np.array([1.0, 2.0, 4.0]), mindspore.float32)
>>> log = ops.Log()
>>> output = log(input_x)
>>> print(output)
[0.        0.6931472 1.3862944]
