Tensor-Add Example

This example shows:

• How to create an InferenceSession
• Load a simple ONNX model which has one Operator: Add
• Create two random Tensors of given shape
• Run the inference using the inputs
• Get output Tensor back
• Access raw data in the Tensor
• Match the results against the exptected values

How to run

1. Download model file add.onnx from examples/models and put it in the current folder.

2. Start an http server in this folder. You can install http-server via

   npm install http-server -g
   

   Then start an http server by running

   http-server . -c-1 -p 3000
   

   This will start the local http server with disabled cache and listens on port 3000

3. Open up the browser and access this URL: http://localhost:3000/

4. Click on Run button to see results of the inference run
