What alternative board would be used to implement this example instead of NUCLEO-32 STM32L432KC EVAL BRD since this board is not available online. please suggest
@abhi-84 Almost any STM32 ARM Cortex-M3 or M4 should work (setting it up in CubeMX might be a little different, depending on the particular MCU or board). Some Cortex-M0 or M0+ MCUs might work...I just haven't tried them yet.
@suman346 @ericobropinto @ShawnHymel Some possible solutions for Unknown format code 'x' for object of type 'str".
I have met this problem but solved it by changing it slightly. So be careful about the file and directory.
From
file.write(hex_to_c_array('./modellite.tflite', c_model_name))
to
file.write(hex_to_c_array(tflite_model, c_model_name))
Then it works.
Create header guard
c_str += '#ifndef ' + var_name.upper() + '_H\n'
c_str += '#define ' + var_name.upper() + '_H\n\n'
-- Here I am facing error
"AttributeError: 'Interpreter' object has no attribute 'upper''
@soumengoroi Check the value of var_name being passed into that function. It should be a string (and set by c_model_name as the argument)
There is a typo in the 3rd code cell. Change versionS to version.
!python --version
@ericobropinto it looks like
format(val, '#04x')
only works whenval
is an integer. In my original code, the tflite model file was a collection (list, I think) of integers that could be iterated over and converted to hex strings (i.e. usingformat()
). That may have changed in recent versions of TensorFlow Lite (as this example is over 2 years old). I'm not sure what format the tflite models are using now.
