Machine learning exmples not working

daniele · December 12, 2024, 9:10am

I tried this:
Camera board: RT1062
OpenMV IDE example : tf_image_classification
mobilenet model : mobilenet_v1_0.25_128_quant.tflite
firmware: 4.5.9
OpenMVIDE: 4.4.7

I didn’t made any change in example script(axcpet for mobilenet_width = “0.25”) and loaded model and mobilenet_labels.txt on CAM.

Result:
Traceback (most recent call last):
File “”, line 33, in
File “ml/model.py”, line 14, in init
ValueError: Failed to allocate tensors
OpenMV v4.5.9; MicroPython v1.23.0-r19; OpenMV IMXRT1060-MIMXRT1062DVJ6A

Could you please help me in finding my mistake?
Thank you

Hi, that example has already been deleted for a coming release. Here’s the new one:

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time=2000)

model = ml.Model("person_detect", load_to_fb=True)
print(model)
