Error message: Device was not found. while launching depthai on virtualbox.

Amjad-JK

I am currently working with the OAK-D Pro W PoE and have encountered an issue while launching it through DepthAI. I have installed DepthAI following the Manual DepthAI installation guide on your website, and all steps went smoothly until I reached the command:

python3 ColorCamera/rgb_preview.py

According to the guide, this command should open a small window displaying a video. However, instead of the expected output, I receive the following error:

RuntimeError: No available devices

Please note the following troubleshooting steps I have taken so far:
- I have ensured the physical connection is correct by following the PoE deployment guide.
- I successfully pinged the OAK-D Pro W PoE, confirming the device is responsive, which suggests the connectivity is not the issue.
- I attempted to resolve the problem by following the debugging suggestions for the "RuntimeError: No available devices" error provided in the PoE deployment guide, but unfortunately, this did not resolve the issue.

I even tried manually including the IP using: device_info = dai.DeviceInfo("169.254.1.222"

Additionally, please note that I am using Ubuntu 24.04 through VirtualBox.

For further detail, I have attached some pictures showing the setup and the error message

Hi @Amjad-JK , your device is not in the same subnet as your computer.

Please see "No DHCP" section on how to specify IP of the device:

erik Hello, Yes I understand that and I have seen the document.

I manually included the IP using the same script that was shown in the picture. However, I still got another error message stating: RuntimeError: Cannot find any device with given device info.

I included as picture in the previous post.

Please let me know if there is any other information that I should provide.

Thank you

Hi, Amjad-JK

Could you add a snippet of the code where you set the device info. It should be passed into the dai.Device() as well.
It's possible that python is selecting a different network interface than the terminal. If you have multiple interfaces (check with ifconfig) make sure the correct one is selected.

Thanks,
Jaka
