Methods#

getCompiledModel

```
getCompiledModel(): CompiledModel
```
It gets the compiled model used by the InferRequest object.
- Returns: CompiledModel
- Defined in: addon.ts:490

getInputTensor

```
getInputTensor(): Tensor
```
It gets the input tensor for inference.
- Parameters:
  - Optional
    idx: number
- Returns: Tensor
  
  The input tensor for the model. If the model has several inputs, an exception is thrown.
- Defined in: addon.ts:496
```
getInputTensor(idx: number): Tensor
```
It gets the input tensor for inference.
- Parameters:
  - Optional
    idx: number
    An index of the tensor to get.
- Returns: Tensor
  
  A tensor at the specified index. If the tensor with the specified idx is not found, an exception is thrown.
- Defined in: addon.ts:503

getOutputTensor

```
getOutputTensor(): Tensor
```
It gets the output tensor for inference.
- Returns: Tensor
  
  The output tensor for the model. If the tensor with the specified idx is not found, an exception is thrown.
- Defined in: addon.ts:509
```
getOutputTensor(idx?: number): Tensor
```
It gets the output tensor for inference.
- Parameters:
  - Optional
    idx: number
    An index of the tensor to get.
- Returns: Tensor
  
  A tensor at the specified index. If the tensor with the specified idx is not found, an exception is thrown.
- Defined in: addon.ts:516

getTensor

```
getTensor(nameOrOutput: string | Output): Tensor;
```
It gets an input/output tensor for inference. If a tensor with the specified name or port is not found, an exception is thrown.
- Parameters:
  - nameOrOutput: string | Output
    
    The name of the tensor or output object.
- Returns: Tensor
- Defined in: addon.ts:525

infer

```
infer(): { [outputName: string] : Tensor};
```
It infers specified input(s) in the synchronous mode. Inputs have to be specified earlier using InferRequest.setTensor or InferRequest.setInputTensor
- Returns:
```
{
[outputName: string]: Tensor;
}
```
- Defined in: addon.ts:460
```
infer(inputData): {
    [outputName: string]: Tensor;
}
```
It infers specified input(s) in the synchronous mode.
- Parameters:
  - inputData: { [inputName: string]: Tensor | SupportedTypedArray; }
    An object with the key-value pairs where the key is the input name and value can be either a tensor or a TypedArray. TypedArray will be wrapped into Tensor underneath using the input shape and element type of the deployed model.
- Returns:
```
{
[outputName: string]: Tensor;
}
```
- Defined in: addon.ts:468
```
infer(inputData): {
    [outputName: string]: Tensor;
}
```
It infers specified input(s) in the synchronous mode.
- Parameters:
  - inputData: Tensor[] | SupportedTypedArray[]
    An array with tensors or TypedArrays. TypedArrays will be wrapped into Tensors underneath using the input shape and element type of the deployed model. If the model has multiple inputs, the Tensors and TypedArrays must be passed in the correct order.
- Returns:
```
{
[outputName: string]: Tensor;
}
```
- Defined in: addon.ts:477

inferAsync

```
inferAsync(inputData): Promise<{
    [outputName: string]: Tensor;
}>
```
It infers specified input(s) in the asynchronous mode.
- Parameters:
  - inputData: Tensor[] | { [inputName: string]: Tensor; }
    An object with the key-value pairs where the key is the input name and value is a tensor or an array with tensors. If the model has multiple inputs, the Tensors must be passed in the correct order.
- Returns:
```
Promise<{
 [outputName: string]: Tensor;
}>
```
- Defined in: addon.ts:485

setInputTensor

```
setInputTensor(tensor): void
```
It sets the input tensor to infer models with a single input.
- Parameters:
  - Tensor
    
    The input tensor. The element type and shape of the tensor must match the type and size of the model’s input element. If the model has several inputs, an exception is thrown.
- Returns: void
- Defined in: addon.ts:532
```
setInputTensor(idx, tensor): void
```
It sets the input tensor to infer.
- Parameters:
  - idx: number
    
    The input tensor index. If idx is greater than the number of model inputs, an exception is thrown.
  - Tensor
    
    The input tensor. The element type and shape of the tensor must match the input element type and size of the model.
- Returns: void
- Defined in: addon.ts:540

setOutputTensor

```
setOutputTensor(tensor): void
```
It sets the output tensor to infer models with a single output.
- Parameters:
  - Tensor
    
    The output tensor. The element type and shape of the tensor must match the output element type and size of the model. If the model has several outputs, an exception is thrown.
