Hi I am trying to validate the .txt file a custom data over 'validate on desktop' option over cube ai but process is not ending at all. Is it necessary that data must be validated on target only.

Hi @Community member​ ,

Custom data validation can be done on desktop and on target. As described in the X-CUBE-AI User Manual, in section 14.2 Custom data set file format?:

"The expected file is a simple text file in csv format with one flattened input tensor by line. The comma is used as a separator."

When you say the "process is not ending at all", is there any additional information displayed in the STM32CubeMX Output log window? (Window -> Outputs)

Best regards,

Guillaume

@Community member​ ,

Looking at your actitracker_raw.txt, it seems that your values are encoded as followed:

# Expected Class Nb, Expected Class Label, Timestamp, In X, In Y, In Z

33,Jogging,49105962326000,-0.6946377,12.680544,0.50395286

33,Jogging,49106062271000,5.012288,11.264028,0.95342433

33,Jogging,49106112167000,4.903325,10.882658,-0.08172209

Your custom dataset file should online include input tensors, that is, assuming your input tensor dimension is 3:

# In X, In Y, In Z

-0.6946377,12.680544,0.50395286

5.012288,11.264028,0.95342433

49106112167000,4.903325,10.882658,-0.08172209

X-CUBE-AI version 3.4.0 allows you to dump NN inference input and output data. If you look at your log when executing a validation, you should be able to see the creation of 3 files:

Creating C:\Users\<username>\.stm32cubemx\ai_valid_inputs.csv

Creating C:\Users\<username>\.stm32cubemx\ai_valid_outputs_model.csv

Creating C:\Users\<username>\.stm32cubemx\ai_valid_outputs_c_model.csv
