Hi there,

I am trying to run Hello AI worlkd on TX2 using jetpack 3.2.1, but I receive some errors during the cmake …/ command.
Attached is the picture for error.

How can I solve this problem?

Hi @farough.nasab, apologies for the delay - moving this topic to the Jetson TX2 forum.

What I recommend is re-flashing with the latest JetPack, which will update GStreamer and make this error go away.

Alternatively, you could clone the 20200714 branch of jetson-inference which should still build on JetPack 3.3.1:

$ git clone --recursive -b 20200714 https://github.com/dusty-nv/jetson-inference
