# makeTensor(descriptor:offset:)

Creates a single-plane tensor with the specified descriptor that shares storage with this buffer.

## Declaration

```swift
func makeTensor(descriptor: MTLTensorDescriptor, offset: Int) throws -> any MTLTensor
```

## Parameters

- `descriptor`: The tensor descriptor configuring the data plane.
- `offset`: The byte offset into the buffer where tensor data begins.

## Return Value

Return Value A tensor, or nil if validation fails.

## Discussion

Discussion This method validates the constraints documented on MTLTensorDescriptor, and additionally requires: offset is 0 when usage contains machineLearning. offset is aligned to 128 bytes if the data plane uses a format MTLTensorDataType. offset is aligned to the size of the data type in bytes otherwise. This method doesn’t create tensors that contain auxiliary planes. Use makeTensor(descriptor:attachments:) instead to create a multi-plane tensor with per-plane buffer backing storage.
