I have installed CUDA Toolkit V10.1.243 with Runfile installation method.
The installation failed at Device Node verification. The following /dev/nvidia* files are generated but the ‘nvidia_uvm’ file is missing.
$ ls nvidi*
nvidia0 nvidiactl nvidia-modeset
I tried running the bash script provided but that dint work.
$ sudo ls -lrt node_verification.sh *
-rwxrwxrwx 1 root root 655 Oct 26 14:30 node_verification.sh
$ sudo bash ./node_verification.sh
mknod: /dev/nvidia0: File exists
mknod: /dev/nvidiactl: File exists
modprobe: ERROR: could not insert ‘nvidia_uvm’: Unknown symbol in module, or unknown parameter (see dmesg)
As a result, tensorflow (2.3.1) package is not able to find the GPU device.
How do I fix this ? and what is this nvidia_uvm file for?
Moreover, I tried installing latest CUDA version 11.1, But had the Same issue.
