and my nvcc version is the following

I tried to run simpleAssert program that came with nvidia sample code and got the following error:

CUDA error at ../../common/inc/helper_cuda.h:779 code=802(cudaErrorSystemNotReady) "cudaGetDeviceCount(&device_count)"

I ran nvidia-bug-report.sh and this is the following file:

Error 802 generally indicates your system requires the NVLink/NVSwitch fabric manager, and you have not installed it.

This will generally be the case for 8-way A100 SXM systems. They require fabric manager to be installed.

Thanks for you response! I have actually already tried to install the fabric manager using sudo apt-get install cuda-drivers-fabricmanager-470. But I get the following error when I try to start it.

(base) ubuntu@ip-172-31-49-222:~$ sudo systemctl start nvidia-fabricmanager
Job for nvidia-fabricmanager.service failed because the control process exited with error code.
See "systemctl status nvidia-fabricmanager.service" and "journalctl -xe" for details.

and here is the error when I try to get the status

(base) ubuntu@ip-172-31-49-222:~$ systemctl status nvidia-fabricmanager.service

It shows version mismatch. But I’m not sure how to install the 470.141.03 since the command I used to install doesn’t include a minor version.

The easy button here is probably to use an image that is set up already. NVIDIA provides some.

In case of 1 GPU card GTX1070 how to solve this problem?

The fabric manager is not needed on such a system and should not be installed on such a system. If it has been installed, remove it. There are no instructions for removal; you remove it like you would any other installed package via the package manager on your OS.

If that does not resolve the issue then the install history on your machine has corrupted the environment. In that case, the only suggestion I have is to reload the OS, and install CUDA using the available installers, following the available instructions.
