Converting onnx model to kmodel

Trying to convert the model according to the instructions K230 nncase Development Guide — K230 Linux+RT-Smart SDK , I get an error:
File “C:\Users\Admin\AppData\Local\Programs\Python\Python310\lib\site-packages\nncase_init_.py”, line 34, in
import _nncase
ImportError: DLL load failed while importing _nncase

Has anyone already tried to do the same?

The problem was related to the fact that on the computers I used,
the processors did not support avx instructions.
onnxruntime requires support for avx instructions.
Problem solved, thank you.
