Startup with a Raspberry 4 #65

Closed Elmit2015 closed 3 years ago

Elmit2015 commented 3 years ago

I need some startup push ;-)

I use a RPi4 with 4 GB RAM.

python3 shows:

Python 3.7.3 (default, Dec 20 2019, 18:57:59) 
[GCC 8.3.0] on linux

As I understand, I need to install first pycoral, tflite_runtime and libedgetpu.

For pyCoral: sudo apt-get install python3-pycoral Also be sure you have the latest version of the Edge TPU runtime. How do I check that?

For tflite-runtime:

echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
sudo apt-get update
sudo apt-get install python3-tflite-runtime

For libedgetpu, please install the debian package:

# None of this is needed on Coral boards
# This repo is needed for almost all packages below
echo "deb https://packages.cloud.google.com/apt coral-edgetpu-stable main" | sudo tee /etc/apt/sources.list.d/coral-edgetpu.list
# This repo is needed for only python3-coral-cloudiot and python3-coral-enviro
echo "deb https://packages.cloud.google.com/apt coral-cloud-stable main" | sudo tee /etc/apt/sources.list.d/coral-cloud.list

curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

sudo apt-get update

sudo apt-get install libedgetpu1-max
sudo apt-get install python3-pycoral
sudo apt-get install python3-tflite-runtime
sudo apt-get install python3-coral-cloudiot
sudo apt-get install python3-coral-enviro

and finally: sh install_requirements.sh

Is the sequence and the commands right?

I tried above, but it failed. Please guide me on how to fix it:

I tested first: vcgencmd version; vcgencmd get_throttled; vcgencmd measure_volts; vcgencmd measure_temp;vcgencmd measure_clock arm; Jun 1 2020 13:24:51 Copyright (c) 2012 Broadcom version 6379679d1ec6a8c746d7e77e015f5b56b939976f (clean) (release) (start_x) throttled=0x0 volt=0.8350V temp=36.0'C frequency(48)=600169920

Does anybody have a hint of what I am missing?

el-tocino commented 3 years ago

Getting a similar error trying to install python3-coral-enviro on a pi zero wh, running buster. Apt update has been completed successfully, anything else I try works. Device worked on an older version of raspbian, as well.

scottamain commented 3 years ago

@Elmit2015 I think you can ignore those errors because they're about the enviro-board, which you don't need for this project. None of the instructions mention running "sudo apt-get install python3-coral-enviro" so why did you do that? (It's definitely interesting that you have this error, but it's not related to this posenet project, so I'm curious how you arrived there.)

Regarding your very first question: "Also be sure you have the latest version of the Edge TPU runtime. How do I check that?" As long as you have the latest version of each, you're all set. The instructions to install the runtime library are in the USB Accelerator setup guide: https://coral.ai/docs/accelerator/get-started#runtime-on-linux (Also, apt-get install python3-pycoral will install the libedgetpu dependency.)

So with both the pycoral library and libedgetpu library installed, you should be all set.

Note: If you tried one of the posenet scripts (such as pose_camera.py) on Raspberry Pi before June 18, then it would not have worked for a very different reason (maybe that was your actual problem but you didn't share that error message). But this project is now setup to support RPI out of the box, so try again.
