ERROR: Can’t start miner, cuda exception in [check_if_cuda_really_exists, 248], invalid argument
I just rebooted my miner, had not run any updates, had not run anything, just rebooted my miner, tried turning t-rex back on, and received the following error: ERROR: Can’t start miner, cuda exception in [check_if_cuda_really_exists, 248], invalid argument
To fix this I had to perform the following
Login to the miner
Type:
sudo bash
apt-get update
apt-get upgrade
y
ubuntu-drivers devices
Check to see if the 450 driver is available:
vendor : NVIDIA Corporation
model : GP102 [GeForce GTX 1080 Ti]
driver : nvidia-driver-390 – distro non-free
driver : nvidia-driver-460-server – distro non-free
driver : nvidia-driver-450-server – distro non-free
driver : nvidia-driver-460 – distro non-free recommended
driver : nvidia-driver-418-server – distro non-free
driver : nvidia-driver-450 – distro non-free
driver : xserver-xorg-video-nouveau – distro free builtin
Now run the following command
apt purge nvidia-driver-460-server
y
apt install nvidia-driver-450-server
y
reboot
Once your miner comes back online, you can now run t-rex fine.
