Does frigate support INTEL-GPU-SRIOV?

[fay000fay]

I am using an n100 CPU, running LXC in PVE 8.2.7, and deploying frigate in a docker with version 0.14.1. I have enabled the CPU's SRIOV function and successfully virtualized 4 virtual GPUs. However, frigate encountered an error，However, if I disable SRIOV, frigate can access the GPU normally. This is very strange, could it be that frigate is not compatible with SRIOV?

Your logs don't show any camera errors so looks like it is working

there is one error below, and GPU is not working

[NickM-27]

Right, there's nothing wrong just means stats don't work. Not sure how we'd fix that exactly

[guoqiang881245]

I also found the same problem. ERROR: Unable to poll intel GPU stats: Failed to detect engines! (No such file or directory), did not seem to support the sriov CPU, did not find a solution for two days, and finally gave up, do not use the sriov driver.

The camera is working properly, the detector cannot be used, and even if it can use the CPU, it is very expensive

是的。我也暂时放弃了。不过我SRIOV还是开着，虚拟核显分给飞牛NAS影视用来解码用是可以的，在飞牛NAS里装了个Intel驱动，就成功调用虚拟GPU了。只是Frigate无论装在LXC，还是虚拟机，还是HA的addon，只要是虚拟的，一律无法调用，切换到物理GPU后，就可以了。

[guoqiang881245]

是的，没什么问题，只是意味着统计数据不起作用。不知道我们该如何解决这个问题

The camera is not a problem, the object detector can not call the GPU
