Yes, I do restart after reinstall nvidia driver (First reinstall 390.77 & reboot & cuda9.0 -> didn’t work, reinstall 384.xx & reboot & cuda9.0 -> also didn’t work. ) I can’t use the machine now, So I’ll add info after doing with cuda9.2 tmr(I don’t know why but I can’t find pytorch-cuda9.1 in conda repository…) . Thank you for reply
