Apex driver failure on Ubuntu 20.04 on Raspberry Pi Compute Module 4. #17

Closed RyanHir closed 3 years ago

RyanHir commented 3 years ago

Hello,

I am trying to use the "Mini PCIe Accelerator" on the Raspberry Pi Compute Module 4 running Ubuntu Mate 20.04 64-bit. I am able to install the drivers and necessary runtimes required. On the device, I have libedgetpu1-std=15.0, python3-pycoral=1.0.1, and gasket-dkms=1.0-14, these are able to run the "USB Accelerator". But when I go to use the PCIe Accelerator, I am unable to get past ValueError: Failed to load delegate from libedgetpu.so.1 when running...

from pycoral.utils import edgetpu

# Works on usb accelerator
tpu = edgetpu.make_interpreter("ssd_mobilenet_v2_coco_quant_postprocess_edgetpu.tflite")

And for debugging purposes, I ran dmesg and found...

apex 0000:01:00.1: Couldn't reinit interupts: -524
apex 0000:01:00.1: Permission checking failed.

This is concerning as the Getting Started page for the M.2/Mini PCIe accelerators say that Ubuntu 16.04 or later is supported on ARMv8. I have the apex driver setup with the proper udev rules and added my user to the group.
