I ran into the same problem using my own training results.

[zzzdddyyy]

I get this problem all the time.
But I found the cause of the problem and came up with a solution.

The key cause of the problem:
Wrong dimension set in model file.

So how do we get the dimensions right?

1st:
Open this website: https://netron.app/

Open your xxx.onnx file in this page

2nd
Find the output result like this:

The output array :[1,25200,7] in my sample

3th
Run the Yolo5NetApp,Set a breakpoint at the point where the program reported an error.

Get run results

The output array's length is 277200 in my sample

4th
The right dimensions = 277022/25200 = 11

5th

Modify your dimensions in model file ,you can run this app.

Last
There may be a better solution!
