Kernel Oops - Bug: 0

[Aeroten]

Hi !
I tried to run the TFLite demo on Siemens IOT 2050 with the PCI E Coral TPU.
Running the classification example in python :

python3 classify_image.py
--model models/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite
--labels models/inat_bird_labels.txt
--input images/parrot.jpg

Gives me

Any idea ?
Thank you in advance for your support !

hey! Could you share some outputs?

Hi Namburger,

Thanks for your kind reply ! Sure, here is the information.

Concerning the kernel I installed the Coral driver generating the headers and adding the name of the headers (linux-headers-iot2050) in the gasket-dkms package from the tutorial (https://coral.ai/docs/m2/get-started/#2-install-the-pcie-driver-and-edge-tpu-runtime). It seems to me it's installed properly.

Maybe interresting for you as well, I get the same error running the demo script without the Edge TPU, that's why I'm posting here.

@Aeroten hello, installation looks good, I've actually never seen this message before o_0
Can you also attach the full dmesg?

[Aeroten]

Hi Namburger,

Yeah, same to me, this is really strange. I'm testing right now one of your C example, to see if it has something to do with python. I'll let you know the result there.

Here is the start dmesg
