Invalid Network Error in loading model and unable to check AI Application.

[KWata.13]

I tried Cube AI like youtube https://youtu.be/grgNXdkmzzQ. But I got some difficulties.

I use Cube MX 5.0.1,Cube AI 3.3.0.

1.   Invalid Network Error

In mcu selection, I selected Github Model file and pushed analyze button in the funtion item. Then I got Invalid network error and difficult to analyze the model.

In the youtube, here : https://youtu.be/grgNXdkmzzQ?t=217

2.   Unable check AI in the Pinout & Configuration Setting

I selected F7 MCU. But the item of Artificial intelligence doesn’t appear in the Application software. I tried to display the item by checking AI in the additional software. But the item doesn’t appear in the Application.

In the youtube, here : https://youtu.be/grgNXdkmzzQ?t=316

Anyone has solutions?

Thank you.

Hi,

Could you provide us the complete output log and the CubeMX log while reproducing the error ?

(CubeMX log is located at: C:\Users\[username]\.stm32cubemx\STM32CubeMX.log)

Thank you

I get the same error when I try and analyse the HAR-CNN-Keras Model from Github: This is the relevant snippet from the STM32CubeMX.Log file:

The console in STM32CubeMX shows:

The following path has no files or directories present:

C:\Users\another\STM32Cube\Repository\Packs\STMicroelectronics\X-CUBE-AI\3.3.0

The parent directory includes the 3.3.0 folder and what looks like an extraction of the the install pack in a TMPUPD folder.

Hope this figures out what the problem is..

Copying the contents of :

C:\Users\another\STM32Cube\Repository\Packs\STMicroelectronics\X-CUBE-AI\TMPUPD_7987620512652994028\Utilities

To:

C:\Users\te192188\STM32Cube\Repository\Packs\STMicroelectronics\X-CUBE-AI\3.3.0\Utilities

Seems to resolve the problem running analyse. It looks like the installer hasn't worked correctly.

[Romain LE DONGE]

There are effectively problems during the installation, try deleting X-Cube-AI from CubeMX, then go to "C:\Users\[username]\STM32Cube\Repository\Packs\STMicroelectronics" and check that X-Cube-AI is no more present (delete it if present). Be sure that no process is using the directory and try re-installing the X-Cube-AI from CubeMX

Additionally what you can try is a manual installation by downloading the plugin here (bottom of the page) : https://www.st.com/en/embedded-software/x-cube-ai.html

Then go to Help > Embedded Software Packages Manager and click on "From Local" to browse the file you just get

Hope this can help

Thank you.

From the log, the probrem may be the instalation fail of the ai pack.

The dedicated folder doesn't exit and I reinstalled it again.

But​ I got the error again.

Finally, I succeeded the execution.

The solution is deleting X-Cube-AI folder completely and reinstalling it again.

Thank you.

Hi, Thanks for your attention. I try to reinstall the stm32cubeMX but it doesn't help. I am analyzing the .onnx format model.

Here is the log information. Can you help me with this problem?
