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:

 Invalid network

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.

[Jonathan Roberts]

I also don't see the "Additional Software" option on the LHS after enabling the AI Application and AI Core settings. From these messages in the log I guess other parts of the install also failed:

[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.

​CubeMX log is here.

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.

Also seeing the same error shown in the CubeMX dialog, but have a different log remark:

[INFO] AIPython:108 - INVALID MODEL: Model saved with Keras 2.2.4-tf but <= 2.2.4 is supported

It appears the latest Keras version appends "tf" unfortunately, and the code may not handle that properly?

[Romain LE DONGE]

You are right for this problem, in the next version of the pack this problem will be fixed

Hi everyone, i am having a similar issue , i get a invalid network error window once i start to analyze. Please find below the log:
