# bindOptimizerData(_:deviceData:with:)

Associates the optimizer and device data you specify along with the tensor.

## Declaration

```swift
func bindOptimizerData(_ data: [MLCTensorData], deviceData: [MLCTensorOptimizerDeviceData]?, with tensor: MLCTensor) -> Bool
```

## Parameters

- `data`: The optimizer data that you want to associate with the tensor.
- `deviceData`: The optimizer device data that you want to associate with the tensor.
- `tensor`: The tensor that you want to associate the data with.

## Return Value

Return Value A Boolean value that indicates whether the data successfully associates with the tensor.
