Critical Problems After NanoEdge Update to Version 5.0.0

Hello ST team, I've encountered some serious issues after updating NanoEdge from version 4.6.0 to the latest 5.0.0 version.

  1. All my training results from version 4.6.0 have disappeared after updating to version 5.0.0. These old training results are important for my paper. How can I recover them? I only performed an update operation, why was all the data lost?
  2. When using NanoEdge version 5.0.0, clicking "create" on any training project doesn't produce any response or pop-up window. I've tried this on two different computers with the same issue. How can I solve this problem? I want to create a new project and start training.
  3. Is there a way to keep old versions of NanoEdge or get an upgrade notification? Yesterday during my group meeting presentation, NanoEdge suddenly prompted me to upgrade, and it would exit if I didn't upgrade. However, the upgrade process was extremely slow - I waited for tens of minutes when it should have only taken a few minutes with my internet speed.

I’m experiencing the same issue. On my PC with an AMD R9 9950X processor, the program gets stuck on the loading screen and never successfully launches.

Hello @qqzlqqzlqqzl,

 

I am sorry to hear that.

 

1/ Concerning your project disappearing, I think the workspace space may have change. Go to settings and look at the path selected (first setting)

On windows, it is supposed to be in C/users/YOURUSER/AppData/Roaming/workspaceNanoEdgeAI

On Linux: /local/home/user/.config/workspaceNanoEdgeAi

 

2/Can you try to create a project than send me the log. They should be in the workspace I write above.
The file I need is nanoedge.log

 

3/It is very strange that it took that long. I will see if there is a way to download the previous version. What I know for sure is that it will only be a temporary solution as the backend for compilation will not support the 4.6 for ever.

 

Have a good day,

Julian

Hello @qqzlqqzlqqzl ,

 

After investigation, there is a bug due a character that is not the same in UTF-8 and GBK (these are encodings).

We found a fix that should correct all your issues.

 

You can activate UTF-8 compatibility with the Chinese version of windows:

Go to Time & Language -> Language & Region -> Administrative language settings -> Change system locale -> and check Beta: Use UTF-8.

 

You may have to restart your pc for it to be applied.

 

Let me know if it worked.

Julian

Hello, yesterday when I was checking the logs, I found:
"2025-04-01 15:39:26,300 exception ERROR 500 Internal Server Error: Unexpected server error due to UnicodeDecodeError: 'gbk' codec can't decode byte 0xa2 in position 281039: illegal multibyte sequence"
This is indeed, as you mentioned, likely an encoding issue. Changing "gbk" to UTF-8 might solve the problem, but this would affect some of my documents and cause them to display as garbled text, so I cannot try this operation. Perhaps I could try it in a virtual machine.

 

These are my three projects, which might help you identify the error.

Hello, I changed the GBK encoding to UTF-8 encoding in the virtual machine, which solved the problem. This is an effective method. Thank you for your help. Additionally, the new interface can display more content, which is helpful for my paper. However, the program often crashes in the virtual machine. I hope this encoding anomaly issue can be fixed as soon as possible.Thank you.

Hello @qqzlqqzlqqzl ,

 

Thank you for the information.

I am glad you like the work we put to improve the interface.

 

Concerning the bug, it will be fixed in the next patch for sure. I transmitted your needs, and I hope they will deploy it as soon as possible.

 

What you can maybe try to reduce the crashes in your virtual machine is to go to the settings in NanoEdge AI Studio and at the bottom, reduce the number of CPU cores used during the benchmark. It will let the VM uses more cores for the rest, maybe reducing the risk of crash.

 

Have a good day,

Julian
