when i was installing the jetpack on my tx2,it shows that :
Error: GIE cannot be installed on device. This may be caused … make sure following packages are installed correctly on device before continuing:
libgie1 libgie-dev
After these packages are installed on device, press Enter key to continue
and then i found that opencv and cmake cannot installed on my tx2
tomorrow i tried again,and the error still exist,but opencv4tegra was installed ,and cmake cannot installed yet
