yolov8

[yolov8]

is it possible to convert a yolov8 model to rknn? or it is not supported on rk3399pro? i know it is possible to convert yolov5 but not sure about yolov8

[Is it possible to run more inferences in parallel on npu?]

Is there a way to run more rknn inferences in parallel on the npu? If yes how?

thank you @tooz

I have tried running your code but then I get either A full buffer was not returned. Try again.     or      DHT sensor not found, check wiring 😕   

the wiring seems to be right.

hello @shenouda, 

have you tried adafruit dht circuit library? adafruit/Adafruit_CircuitPython_DHT: CircuitPython support for DHT11 and DHT22 type temperature/humidity devices (github.com)

dht22 requires 3 pin connectors (vcc, gnd and gpio), you can use it on tinker edge r

to install the package:

pip3 install adafruit-circuitpython-dht --user

details can be found here: https://github.com/adafruit/Adafruit_CircuitPython_DHT#readme

Hi @tooz thank you for your reply.

when I try to do import board i get the following error:

NotImplementedError: Adafruit-PlatformDetect version 3.40.2 was unable to identify the board and/or microcontroller running the Linux platform. Please be sure you have the latest packages running: 'pip3 install --upgrade adafruit-blinka adafruit-platformdetect'

i tried running  'pip3 install --upgrade adafruit-blinka adafruit-platformdetect' but still getting the same error. Do you have any suggestion?

I can't find a compatible library to read temperature and humidity from dht sensor in python..

[can't access GPIO with python periphery library]

Hi I am new to this forum. I am trying to use python-periphery library to use the pins  on the board.

if I do :

from periphery import GPIO

gpio3 = GPIO(3,"in")

I get the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1017, in _open
    with open("/sys/class/gpio/export", "w") as f_export:
PermissionError: [Errno 13] Permission denied: '/sys/class/gpio/export'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/linaro/Desktop/temp_hum.py", line 7, in <module>
    gpio3 = GPIO(3,"in")
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 999, in __init__
    self._open(line, direction)
  File "/usr/local/lib/python3.7/dist-packages/periphery/gpio.py", line 1020, in _open
    raise GPIOError(e.errno, "Exporting GPIO: " + e.strerror)
periphery.gpio.GPIOError: [Errno 13] Exporting GPIO: Permission denied

 

Any Idea how to solve this?
