Input and output of onnx model – script MetaTrader 5

ONNX is an open-source format for representing machine learning models. The script allows the user to select an ONNX model file through a file dialog. It then creates an ONNX session, retrieves information about the input and output tensors in the model, and prints this information to the console.

Here’s a breakdown of the script’s functionality:

1. File Selection:

   • The script prompts the user to select an ONNX model file through a file dialog.

2. Model Processing:

   • It displays a message indicating that the ONNX model file is being processed, mentioning the file name and indicating that debug logs are enabled.

3. ONNX Session Creation:

   • It creates an ONNX session using the selected model file.
   • If there is an error during the creation of the session, it prints an error message to the console and exits the script.

4. Input Information:

   • It retrieves and prints information about the input tensors in the ONNX model.
   • For each input tensor, it prints the input index, input name, and additional information retrieved using the OnnxGetInputTypeInfo function.

5. Output Information:

• It retrieves and prints information about the output tensors in the ONNX model.
• For each output tensor, it prints the output index, output name, and additional information retrieved using the OnnxGetOutputTypeInfo function.
