Can not covert onnx model to nb format for stm32mp25 target

[charlie128]

Hello

I want covert my quantized onnx model(develop by pytorch)  to .nb format, to enable stm32mp257 npu accelerate.

I use ST Edge AI Core V2.0.0,(V2.1.0 has been not support stm32mp257).when I run generate command,it report lose file "onnx_ruler_db.json".

run command：

/opt/ST/STEdgeAI/2.0/Utilities/linux/stedgeai generate -m ./xxx.onnx --target stm32mp25

command result：

ST Edge AI Core v2.0.0-20049

LOAD ERROR: [Errno 2] No such file or directory: '/opt/ST/STEdgeAI/2.0/Utilities/linux/lib/python3.9/site-packages/onnx_ruler_db.json'

Hello @charlie128,

it is a right issue. installing the stedgeai core in /opt is the issue. 

I advise to install it elsewhere. Or maybe use sudo or chmod.

Let me know if it helped.

Have a good day,

Julian

Hi @Julian E. 

Thank you very much for your reply. This is indeed an issue with the permissions of the installation directory. The problem was resolved after I used chown to change the directory of the ST tool to the user I am using.

The reason this problem was difficult for me to solve before is that it was not caused by abnormal permissions of the 'onnx_ruler_db.json' file itself, but by permission issues with some other files, which prevented this file from being generated. That's why I couldn't find this file before.

Therefore, the log report of this issue was quite misleading, making it difficult to associate it with a permission problem.

Thanks again.
