ONNX model file is not found after deployment on MonsterASP (works locally)

Customer25003

Hello Support Team,

We are deploying an ASP.NET 8 Web API application to MonsterASP.

The application uses an ONNX AI model file located at: Utils/VisualModels/mobilenetv2.onnx
After deploying to MonsterASP, we receive the following error:
[ErrorCode:NoSuchFile] Load model Utils/VisualModels/mobilenetv2.onnx failed.
File doesn’t exist.
This indicates that the ONNX file is either not copied to the hosting environment or cannot be accessed from the directory after deployment.

My structure base web api

Thank you!

Hello @Customer25003,
it looks like your "mobilenetv2.onnx" file wasn't included in deployment because Visual Studio doesn't automatically copy .onnx files. Check (via FTP or WebFTP access) if this file is present on website after deployment.

You need to tell Visual Studio explicitly include "mobilenetv2.onnx" with deployment:

Right-click on file Utils/VisualModels/mobilenetv2.onnx in Visual Studio
Click Properties
Set Copy to Output Directory to: Copy if newer
Set Build Action to: Content

Following your instructions,
I right-clicked on my model and selected publish file.
Then I redeployed and the problem was solved.

Thank you for your support. Have a nice day! ദ്ദി/ᐠ - ⩊ -マ.ᐟ
