# Sample of Using Batch
|
||||
|
||||
## Overview
|
||||
|
||||
This sample demonstrates how to override named dimensions to concrete values using LearningModelSessionOptions in order to optimize model performance. This feature will first be released in the 1.5 WinML redistributable.
|
||||
|
||||
## Requirements
|
||||
|
||||
- [Visual Studio 2017 - 15.4 or higher](https://developer.microsoft.com/en-us/windows/downloads)
|
||||
- [Windows 10 - Build 18362 or higher](https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso)
|
||||
- [Windows SDK - Build 18362 or higher](https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewSDK)
|
||||
- Visual Studio Extension for C++/WinRT
|
||||
|
||||
Do the following to add the C++/WinRT extension in Visual Studio.
|
||||
1. Go to **Tools > Extensions and Updates**.
|
||||
2. Select **Online** in the left pane and search for "WinRT" using the search box.
|
||||
3. Select the **C++/WinRT** extension, click **Download**, and close Visual Studio. The extension should install automatically.
|
||||
4. When the extension has finished installing, re-open Visual Studio.
|
||||
|
||||
|
||||
## Build the sample
|
||||
|
||||
1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
|
||||
2. Start Microsoft Visual Studio 2017 and select **File > Open > Project/Solution**.
|
||||
3. Starting in the folder where you unzipped the samples, go to the **Samples** subfolder, then the subfolder for this specific sample (**Sample\BatchSupport**). Double-click the Visual Studio solution file (BatchSupport.sln).
|
||||
4. Confirm that the project is pointed to the correct SDK that you installed (e.g. 18362). You can do this by right-clicking the project in the **Solution Explorer**, selecting **Properties**, and modifying the **Windows SDK Version**.
|
||||
5. Confirm that you are set for the right configuration and platform (for example: Debug, x64).
|
||||
6. Build the solution (**Ctrl+Shift+B**).
|
||||
|
||||
## Run the sample
|
||||
|
||||
1. Open a Command Prompt (in the Windows 10 search bar, type **cmd** and press **Enter**).
|
||||
2. Change the current folder to the folder containing the built EXE (`cd <path-to-exe>`).
|
||||
3. Run the executable as shown below. Make sure to replace the install location with what matches yours:
|
||||
```
|
||||
NamedDimensionOverrides.exe
|
||||
```
|
||||
4. You should get output similar to the following:
|
||||
```
|
||||
Loading modelfile 'D:\repos\Windows-Machine-Learning\Samples\NamedDimensionOverrides\x64\Release\candy.onnx' on the CPU
|
||||
Binding...
|
||||
Running the model...
|
||||
model run took 1156 ticks
|
||||
```
|
||||
|
||||
## Key Step Walkthrough
|
||||
|
||||
### 1. Create Session with named dimension override session option:
|
||||
```C++
|
||||
LearningModelSessionOptions options;
|
||||
options.OverrideNamedDimension(L"None", static_cast<uint32_t>(imageNames.size()));
|
||||
|
||||
LearningModelSession session = LearningModelSession(model, device, options);
|
||||
```
|
||||
|
||||
### 2. Bind Inputs
|
||||
```C++
|
||||
// Load input that match the overriden dimension
|
||||
std::vector<VideoFrame> inputFrames = {};
|
||||
for (hstring imageName : imageNames) {
|
||||
auto imagePath = static_cast<hstring>(FileHelper::GetModulePath().c_str()) + imageName;
|
||||
auto imageFrame = FileHelper::LoadImageFile(imagePath);
|
||||
inputFrames.emplace_back(imageFrame);
|
||||
}
|
||||
|
||||
// bind the inputs to the session
|
||||
LearningModelBinding binding(session);
|
||||
auto inputFeatureDescriptor = model.InputFeatures().First();
|
||||
binding.Bind(inputFeatureDescriptor.Current().Name(), winrt::single_threaded_vector(std::move(inputFrames)));
|
||||
```
