pytorch3d.common

pytorch3d.common.get_device(x, device: str | device | None = None) → device

Gets the device of the specified variable x if it is a tensor, or falls back to a default CPU device otherwise. Allows overriding by providing an explicit device.

Parameters:

• x – a torch.Tensor to get the device from or another type

• device – Device (as str or torch.device) to fall back to

Returns:

A matching torch.device object

pytorch3d.common.make_device(device: str | device) → device

Makes an actual torch.device object from the device specified as either a string or torch.device object. If the device is cuda without a specific index, the index of the current device is assigned.

Parameters:

device – Device (as str or torch.device)

Returns:

A matching torch.device object
