mindspore.ops.csr_relu

mindspore.ops.csr_relu(x: CSRTensor)[source]

Computes ReLU (Rectified Linear Unit activation function) of input csr_tensors element-wise.

It returns max(x, 0) element-wise. Specially, the neurons with the negative output will be suppressed and the active neurons will stay the same.

\[ReLU(x) = (x)^+ = \max(0, x)\]

Parameters

x (CSRTensor) – Input CSRTensor.

Returns

CSRTensor, with the same dtype and shape as the x.

Raises

TypeError – If dtype of x is not a number.
TypeError – If x is not a CSRTensor.

Supported Platforms:: Ascend GPU CPU

Examples

>>> from mindspore import dtype as mstype
>>> from mindspore import Tensor, ops, CSRTensor
>>> indptr = Tensor([0, 1, 2, 2], dtype=mstype.int32)
>>> indices = Tensor([3, 0], dtype=mstype.int32)
>>> values = Tensor([-1, 2], dtype=mstype.float32)
>>> shape = (3, 4)
>>> x = CSRTensor(indptr, indices, values, shape)
>>> output = ops.csr_relu(x)
>>> print(output.values)
