Running pipeline on Docker container

Hi magallardo ,

Sorry about the delay. I thought I saw a reply to this but it must have been a different thread. We do have a Docker Container that could be used here.

Let me ping the team for help here - as I haven't personally used this (let alone on a Pi).

Thanks,
Brandon

Hi JosephMtz69 ,
Are you maybe using a PoE version of DepthAI device? Since they communicate over the network, --net host param should be provided, so that our API can correctly discover the device

@JosephMtz69 I don't have this board on my end, but I do have Jetson Nano, so will try running docker container there and see if I can recreate, will circle back

I've actually been running into a similar issue. It looks like regardless of what I do, I keep getting the same issue to persist. My goal is to run both the rgb_preview and the deptahi_demo.py examples in the same docker container on my unbuntu desktop.

I initially tried using the depthai-library image from (https://hub.docker.com/r/luxonis/depthai-library). When using that image, I was able to connect to my OAK-D and ran the rgb_preview.py example. However, when I tried cloning depthai.git and installing the requirements into the container to run depthai_demo.py, I'd get the following error:

File "depthai_demo.py", line 18, in <module>
from depthai_helpers.arg_manager import parseArgs
File "/app/depthai/depthai_helpers/arg_manager.py", line 10, in <module>
from depthai_sdk.previews import Previews
File "/app/depthai/depthai_sdk/src/depthai_sdk/init.py", line 4, in <module>
from .managers import *
File "/app/depthai/depthai_sdk/src/depthai_sdk/managers/init.py", line 4, in <module>
from .pipeline_manager import PipelineManager
File "/app/depthai/depthai_sdk/src/depthai_sdk/managers/pipeline_manager.py", line 7, in <module>
class PipelineManager:
File "/app/depthai/depthai_sdk/src/depthai_sdk/managers/pipeline_manager.py", line 32, in PipelineManager
_depthConfig = dai.StereoDepthConfig()
AttributeError: module 'depthai' has no attribute 'StereoDepthConfig'

Assuming some packages may have been missing, I created a dockerfile to install all the dependencies from install_dependencies.sh. However, when I tried to run depth_demo.py in a container, it gave the same issue.

I then tried using the base image instead in my dockerfile, (https://hub.docker.com/r/luxonis/depthai-base). While I was no longer getting the error from before, I kept getting an error saying

File "ColorCamera/rgb_preview.py", line 24, in <module>
with dai.Device(pipeline) as device:
RuntimeError: Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

and a similar error when I attempted to run depthai_demo.py. I tried including the following below to my docker file, however that didn't work either.

RUN wget https://github.com/libusb/libusb/releases/download/v1.0.24/libusb-1.0.24.tar.bz2 && \
tar xf libusb-1.0.24.tar.bz2 && \
cd libusb-1.0.24 && \
./configure --disable-udev --prefix="$PWD/install_dir" && \
make -j && \
make install
ENV LD_LIBRARY_PATH="$PWD/libusb-1.0.24/install_dir/lib":$LD_LIBRARY_PATH

Then I tried using a python base image similar to https://github.com/luxonis/depthai-docker/blob/master/Dockerfile-depthai however it was missing all the dependencies. I went back and updated the dockerfile to include the install_dependencies.sh but ran into the same issue again where the device couldn't be found as shown below.

File "depthai_demo.py", line 575, in run
self.instance.run_all(self.conf)
File "depthai_demo.py", line 76, in run_all
self.setup(conf)
File "depthai_demo.py", line 153, in setup
self.device = dai.Device(self.pm.pipeline.getOpenVINOVersion(), self.deviceInfo, usb2Mode=self.conf.args.usbSpeed == "usb2")
Failed to find device after booting, error message: X_LINK_DEVICE_NOT_FOUND

All the containers used the same arguments of

docker run --rm -it\
--privileged \
-v /dev/bus/usb:/dev/bus/usb \
--device-cgroup-rule='c 189:* rmw' \
-e DISPLAY=$DISPLAY \
-v /tmp/.X11-unix:/tmp/.X11-unix \
--entrypoint /bin/bash imageName

Each dockerfile also included RUN echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | tee /etc/udev/rules.d/80-movidius.rules in case it wasn't set. I'm able to see the usb from within the container and even hear an initial click sometimes but it never connects to it.

Please advise.

lead_dev JosephMtz69 I was just able to build a new docker container and access OAK-D from it, running rgb_preview.py script.

To use it now, please do the following

cd depthai-python
git checkout enable_multiarch_build
git submodule update --init --recursive
xhost local:root
docker build -t depthai -f ci/Dockerfile .
docker run --rm --privileged -v /dev/bus/usb:/dev/bus/usb --device-cgroup-rule='c 189:* rmw' -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix depthai python3 /depthai-python/examples/ColorCamera/rgb_preview.py

PR with this Dockerfile changes is here - https://github.com/luxonis/depthai-python/pull/270 - and as soon as we manage to make CI work, we'll have these docker images updated on the dockerhub automatically

Luxonis-Lukasz I normally have a difficult time with the dockerfiles because it always fails on the line

RUN wget http://docs.luxonis.com/_static/install_dependencies.sh && chmod +x install_dependencies.sh && ./install_dependencies.sh

and gives the same error as shown in the attached image. Also, I can run rgb_preview.py, however the dockerfile anytime I attempt to run depthai_demo.py using the depthai repo from within the container, it fails to run saying that a device could not be found.

Yes, I fixed this issue in the mentioned branch. It failed as it wanted to set udev rules where we use libusb without udev. Now, docker container has its own dependencies install script, adjusted to run with root user and without udev

Luxonis-Lukasz ran into the issue shown in the first image where it failed due to not finding sudo. After including sudo into the dockerfile, encountered the same issue again with the line

RUN wget http://docs.luxonis.com/_static/install_dependencies.sh && chmod +x install_dependencies.sh && ./install_dependencies.sh

saying it returned a non-zero value

Yes, it should be merged soon, working on arm runners to build the image automatically and upload it to dockerhub, so that the image gets updated with every release

@Luxonis-Lukasz ... thank you and very good .. just keep me posted when that merge happens .... that way I can remove from my local Dockerfile build that part that specifies the branch .. thanks again

JosephMtz69 Happy to help! Actually, it might be merged even today as we just managed to make the workflows running - https://github.com/luxonis/depthai-python/pull/270
The images will be deployed in 3 variants:

• luxonis/depthai-library:armv7-<ref> - for armv7 hosts (linux/arm architecture)
• luxonis/depthai-library:ubuntu-<ref> - for arm64 hosts (linux/amd64 architecture)
• luxonis/depthai-library:armv8-<ref> - for armv8 hosts (linux/arm64 architecture)

<ref> is either a version tag or branch name (main or develop), so there will be a plentiful of images to choose from. We'll also update the docs once this PR is merged

JosephMtz69 Changes just got merged to the develop branch, so with the next release they'll be available on main
