ONNX Runtime ONNXRuntimeError: [ONNXRuntimeError] : 3 : NO_SUCHFILE : Load model from model.onnx failed: No such file

What is ONNX Runtime ONNXRuntimeError: [ONNXRuntimeError] : 3 : NO_SUCHFILE : Load model from model.onnx failed: No such file

Understanding ONNX Runtime

ONNX Runtime is a high-performance inference engine for machine learning models in the Open Neural Network Exchange (ONNX) format. It is designed to accelerate the deployment of machine learning models across various platforms and devices. ONNX Runtime supports a wide range of hardware and provides optimizations to ensure efficient model execution.

Identifying the Symptom

When using ONNX Runtime, you might encounter the following error message:

ONNXRuntimeError: [ONNXRuntimeError] : 3 : NO_SUCHFILE : Load model from model.onnx failed: No such file

This error indicates that ONNX Runtime is unable to locate the specified model file, resulting in a failure to load the model.

Exploring the Issue

Understanding the Error Code

The error code NO_SUCHFILE suggests that the file path provided to ONNX Runtime is incorrect or the file does not exist at the specified location. This is a common issue when the file path is mistyped or the file has been moved or deleted.

Common Causes

Incorrect file path specified in the code.The model file has been moved or deleted.File permissions prevent access to the model file.

Steps to Fix the Issue

Verify the File Path

Ensure that the file path specified in your code is correct. Double-check for any typographical errors or missing directories. For example:

import onnxruntime as ortsession = ort.InferenceSession("/path/to/your/model.onnx")

Make sure /path/to/your/model.onnx is the correct path to your model file.

Check File Existence

Verify that the model file exists at the specified location. You can use the following command in your terminal or command prompt to check:

ls /path/to/your/model.onnx

If the file does not exist, you will need to locate it or regenerate it if necessary.

Ensure Proper Permissions

Ensure that the file has the appropriate permissions for reading. You can modify the permissions using:

chmod +r /path/to/your/model.onnx

This command grants read permissions to the file, allowing ONNX Runtime to access it.
