Installing Benchbot on a GPU-accelerated VM? #8

Closed achiatti closed 4 years ago

achiatti commented 4 years ago

Hi, I have tried to install Benchbot from a Google Cloud Platform VM with GPU (Nvidia Quadro virtual workstation). All the Nvidia drivers are mounted correctly and visible from nvidia-smi. However the Benchbot install script fails because it cannot access the graphics card: image

Is there any alternative way to install Benchbot without direct access to the physical card?

Thanks!

Thanks for sharing the issue with us @achiatti.

The check I have there is too restrictive and has caused issues in other cases. I'm doing a minor version update at the moment to improve the check, and I'd like to make sure the fix addresses the issue you're having as well. Are you able to post the output of lspci -nn on that VM for me so I can ensure my update addresses your issue?

As a hack so you can get up & running immediately, you can disable the check by commenting it out in the checks_list_pre variable in the install script:

Let me know if you have any further issues.

Thanks for the information @achiatti. This confirms it is the same issue (card not being called "VGA compatible controller") which I've addressed with commit 46af27cc25af429a604f2ce58e3e37802e5b379a.

The fix will be live for everyone when I merge those bug fixes into master / do the next release in a couple of days.

Fix released in 258bd60 as part of release v1.0.2.

Simply re-run benchbot_install to update.
