Nvidia-smi :Failed to create a DMA mapping!

I am experiencing a strange problem , when i give nvidia-smi , i am getting a message " No devices were found"

I have checked others asking same question and i have tried several approaches still the problem persists

I tried dmesg | grep NVRM and this the problem i am facing , how to resolve this issue ? . I am using ubuntu 20.04

dmesg | grep NVRM
