Hi
I am following this material to start using STM32 for AI. I have got to the data validation step on page 29 of the document. It works fine while validating using random numbers.
But while trying to validate using the dataset, I get the error:
TOOL ERROR: cannot reshape array of size 1317858 into shape (219643,90,3,1)
Could I please know what should be the validation dataset?

Hello,
What dataset are you using to validate your model ?
From what I can see, it seems that there is a shape problem in your dataset: (1317858/3 = 439286; 439286/90 = 4880.955 => not an integer), could it be possible that samples are missing maybe ?
Looking at the shape, it looks like an array of size 59303610 (219643*90*3*1) is required
Best regards,
Romain

Hi Romain
I am using a dataset that I collected on-site from a mmWave RADAR.
I'll check the dataset to determine whether or not samples are missing.
Could you please recommend the train: test: validate data size ratio that should be used?
Thank you

Hello,
I'm not a Data Scientist expert and it depends on your data and total dataset size, but I usually use the following split:
Hope this can help !
