Deep Learning Tool and WSL Files

Hi,

New to B&R and am trying to install DLT v5_29.0.2. When opening DLT from AS4 a pop-up shows “Hailo WSL Image needs to be installed or updated”. It then downloads ubuntu-jammy-22.04.tar.gz from git. It then fails. I presume this is required to use a VSC523 smart camera. I was trying on a virtual machine (sent down rabbit hole of VM settings) first but then gave up and tried on a normal pc. Both had the same issue. Any help would be much appreciated.

It is documented in the Automation Help that the installation of Hailo WSL Image ofter fails on the first try and that you should just try again.

Hi,

Thanks for the quick reply. I have followed that advice directly on laptop and on the VM I was trying to setup. I have probably tried about 6 times on each (closing the cmd.exe window and just pressing the Install Hailo WSL Image button) but I get the same fail each time.

Kenneth, I also experienced the script failing when it tries to download the WSL image. Looking in the location where that script is located:

C:\Program Files\BRAutomation4\AS412\AS\TechnologyPackages\mappVisionDeepLearningTool\5.30.5003\DLT\extensions\hailo\wsl

The image, named “ubuntu-jammy-22.04.tar.gz” should be around 30 MB in size. If you see that yours is not that size, then the script’s download failed partway through. Find the URL to the image in the “install_wsl_distro_hailo2.cmd” file’s “IMAGE_SOURCE” variable and download it with an internet browser. You can then:

  1. Copy the image from your Downloads into “extensions/hailo/wsl”
  2. Rename the image to “ubuntu-jammy-22.04.tar.gz” so the script will recognize it
  3. Edit “install_wsl_distro_hailo2.cmd” to remove the block that starts with “if exist %IMAGE_FILE%”, to ensure that your image is not deleted and redownloaded.
  4. Run the “install_wsl_distro_hailo.cmd” script again so it can install the image and change the WSL settings to the recommendations for the DL Tool.

You will know you are successful when the script starts installing python packages.

Hello,
While getting WSL and related files ready, we came across following error:
Has anyone else had this issue ?

Seems to be a “TimeoutError” so most likely just some kind of a network connectivity issue.

I would just try again.
