Edge Insights for Retail - Video Analytics Serving not working


I have downloaded and installed the Edge Insight for Retail package successfully in a clean and fresh installed Ubuntu 18.04.

The list command say that my installation is OK

I proceeded to execute the Video Analytics Serving example posted in The commands are posted below, it shows the container running.

When I try to execute the "Run the Sample Application" step, I get a "Invalid Pipeline or Version" message:

test@test-NUC8i7HVK:~/Downloads/edge_insights_retail$ curl localhost:8080/pipelines/object_detection/2 -X POST -H 'Content-Type: application/json' -d '{ "source": { "uri": "", "type": "uri" }}'
"Invalid Pipeline or Version"


I checked the logs of the created container, and it is complaining about missing libraries and commands.

Any hints?

Hi Nico,

Did you follow the Install Package Modules section (link below) to install the dependencies from the configuration.xml file?

1) Open a terminal window.

2) Go to the edge_insights_retail/ directory.

3) Run the install command:./edgesoftware install



Hello Weng,

Yes, I followed the Package Modules section to install my dependencies.

The process took a couple of hours, and at the end I had all the images required to run the Video Analytics Serving Tutorial.

I was able to build the original video analytics serving project in (took another couple of hours), and the examples from that repo are working fine for me. 

It looks like the image built during the installation step or the documentation from the tutorial is bad, because there is no "/pipelines/object_detection/2" API available in the installed image


I have installed a blank ubuntu 18.04 today and went through the complete installation process from scratch, and now I can use the Video Analytics Serving Tutorial without problems!

Apparently there was an installation problem the first time that prevented me from using it.

It is unfortunately that the installation process takes a couple of hours thought, but it is working now!



We have improved our documentation that demonstrates how to avoid the long initial build time by using a pre-built image. Let us know if that helps:

ok, glad to hear that and thanks for sharing the result.
