hi,
i am working on jetson Xavier NX box,
i updated to jetpack 5.0.1 and deepstream6.1 right now.
before i setup ARCH= -gencode arch=compute 72 for NX to train some models.
but i cmake another file yesterday it detected arch-gencode 75!
so i am confuse right now, should i setup 72 or 75 for jetson xavier nx when i trainning?
thank you very much!
Hi @wilicyy, Xavier is compute_72 / sm_72

Perhaps the cmake file you ran wasn’t properly configured to detect the Jetson GPUs.
