Jetson 2.2 : Examples can't open data file?

Autonomous Machines Jetson & Embedded Systems Jetson TX1

Hello,

I’ve installed Jetson 2.2 on my TX1 with the 64-bit user space configuration. When I try to run the VisionWorks demos, the programs can not open the data files. I know the data files can be opened because I can play them with a standard media player. For example:

ubuntu@tegra-ubuntu:~/VisionWorks-1.4-Samples/bin/aarch64/linux/release$  ./nvx_demo_hough_transform

VisionWorks library info:
	 VisionWorks version : 1.4.3
	 OpenVX Standard version : 1.0.1

Error: Can't open source URI /home/ubuntu/VisionWorks-1.4-Samples/bin/../data/signs.avi

Has anyone else been able to run the demos?

Thanks

I reinstalled Jetpack 2.2 from scratch and now the examples work.

I experience the very same problem. Is there another solution than to reinstall from scratch? I don’t want to employ all modifications again, e.g. remove Unity. (nVidia, why Unity desktop? Why? This doesn’t make sense for a development board where one wants to be productive.)

Hi waterjet,

Have you checked the Installation Guide section in VisionWorks 1.4 Documentation from below link?
[url]http://developer.nvidia.com/embedded/dlc/visionworks-1-4-documentation-for-l4t-24-1[/url]
There should be some information for your reference.

Thanks
