# torch.nn.functional.max_pool1d¶

torch.nn.functional.max_pool1d(input, kernel_size, stride=None, padding=0, dilation=1, ceil_mode=False, return_indices=False)

Applies a 1D max pooling over an input signal composed of several input planes.

Note

The order of ceil_mode and return_indices is different from what seen in MaxPool1d, and will change in a future release.

See MaxPool1d for details.

Parameters:
• input – input tensor of shape $(\text{minibatch} , \text{in\_channels} , iW)$, minibatch dim optional.

• kernel_size – the size of the window. Can be a single number or a tuple (kW,)

• stride – the stride of the window. Can be a single number or a tuple (sW,). Default: kernel_size

• padding – Implicit negative infinity padding to be added on both sides, must be >= 0 and <= kernel_size / 2.

• dilation – The stride between elements within a sliding window, must be > 0.

• ceil_mode – If True, will use ceil instead of floor to compute the output shape. This ensures that every element in the input tensor is covered by a sliding window.

• return_indices – If True, will return the argmax along with the max values. Useful for torch.nn.functional.max_unpool1d later
