Unable to run deptai-python library for OAK-D

elitearmedforce

Hello,
After going through official documents DepthAi and modified some commands to install it on my pc(dependency script). Still facing issue with the first demo example(screenshot attached).

Device Specs:
OS: Linux Mint 20.04.1 LTS
Architecture: x86_64

Started from here:

Dependencies mentioned in script:
sudo wget -qO- http://docs.luxonis.com/_static/install_dependencies.sh | bash
ran these commands instead of the script:
sudo apt install -y build-essential libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev python-dev libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev ffmpeg libsm6 libxext6 libgl1-mesa-glx
Then tried PyPi install:
pip3 install depthai
Testing the demo:

git clone https://github.com/luxonis/depthai-python.git
cd depthai-python/examples
pip3 install opencv-python-contrib
python3 01_rgb_preview.py

Sadly didn't work was getting this error: Screenshot attached above
RuntimeError: Failed to find device (ma2480), error message: X_LINK_DEVICE_NOT_FOUND

So I tried to build from source:

sudo apt-get -y install cmake libusb-1.0-0-dev build-essential
cd depthai-python
git submodule update --init --recursive
python3 setup.py develop

Still same error.

So to check whether it is a device issue or device inserted properly,
I tried checking first in linuxmint with command lsusband usb-device. Detected with no issue.

I tried installing it in Windows 10, it worked properly without any issue.

Hello, seems to me that you are missing some dependencies. Is there a reason why you installed the the packages manually instead of running the script? Could you try to run it as well? Thanks!

erik Apologies for late reply.

erik Is there a reason why you installed the packages manually instead of running the script?

As I mentioned, the script is written to detect ubuntu os and install all dependencies not linux mint os coz of $ID variable in the script. So i had to run it manually.

I figured out the problem, by running the script in Ubuntu os VM and found that I missed a line from the script to run
Missing part:

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="03e7", MODE="0666"' | sudo tee /etc/udev/rules.d/80-movidius.rules
sudo udevadm control --reload-rules && sudo udevadm trigger

Hello elitearmedforce,
great that you got it working. So the script returned "ERROR: Distribution not supported"? I will try it in VM, so we fix the script.
Thanks, Erik

elitearmedforce Thanks! This worked for me. Running on Manjaro and was getting the same issues. Thanks again.

erik Hey,

erik So the script returned "ERROR: Distribution not supported"?

Yes, that is why I had to run it manually.

erik will try it in VM, so we fix the script.

That will be great

Thanks,

Brandon

@erik - just for posterity, I think you did a PR to fix this. Can you share it here when you get a second?

erik

Yes, here it is: https://github.com/luxonis/depthai-python/pull/179
