Greetings.
I am following the instructions to get a custom yolov5 converted to rknn for use with a Luckfox Pico max.
All the versions are according to spec and when i try to convert any yolov5, including the default coco one, i am getting illegal isntrction/core dump errors.
See messages bellow

Any idea what the problem is ?

Hello, it seems that the input parameters for your command are incorrect and lack the quantization option. Here is the command I executed in the same directory based on the official documentation for your reference.

Thanks for the response.
The problem was that the ubuntu VM i was using was missing the AVX cpu command and most/all of AI software these days requires it (tensorflow , pytorch etc)
Enabling the command resolved it.
I think there should be a mention of it on the wiki, as during my searches i found a lot of people with the same problem

Thank you for your feedback. We will update the WIKI after verification.
