Runtime error

Hi @BestWishYsh , we've assigned ZeroGPU to this Space. Please check the compatibility and usage sections of this page so your Space can run on ZeroGPU.

thanks, let me check

BTW, it would be nice if you could provide more info, like arXiv link, GitHub URL, etc., when opening a grant request. Your request was tagged as a spam as it didn't have meaningful info.

i am sorry, thanks for your suggestion

@hysts hi, I have set @spaces.GPU(), but it still shows RuntimeError: No CUDA GPUs are available. Do you know how to fix it, thanks.

Can you provide more info about the error, like a stack trace?

Is duration＝240s too long?

Thanks! I've been looking into the issue, but so far haven't been able to resolve it. The fact that this Space takes like 10 minutes or so just to restart is making debugging difficult. Anyway, I'll let you know once I find something.

Well, not 100% sure what is the cause of the error, but looks like this diff fixes the CUDA error:

This should resolve the current error, but when I run the Space, the inference took more than the specified duration, which is 180 seconds, and the "GPU task aborted error" occurred. Maybe you can decrease the number of inference steps to avoid the error, though.

Thanks a lot, but is the maximum time of ZeroGPU only 180s? Reducing the step will seriously reduce the generated quality ...

Well, actually, I don't know about it. cc @cbensimon

It seems that the longest duration is only 120s

https://huggingface.co/spaces/zero-gpu-explorers/README/discussions/118

But your Space doesn't seem to raise the maximum duration error with duration=180.

The discussion is a bit old and the bug that showed -1 day or something has already been fixed, so I'm not sure but maybe the 120 second issue in the discussion might have been fixed as well.

The current error is:

Does this error mean that users need to subscribe to enterprise hub for it to run the hf space? But it seems that other spaces using zerogpu do not need ...

Ah, ok, it involves a couple of known issues of spaces.

1. There's a bug where the quota error is raised when the remaining quota is exactly the same as the specified duration.
2. There's a bug where users are considered not logged in when the @spaces.GPU decorator is added to inner functions.

You can avoid the second issue by adding an attribute to the outer function, like wrapper_fn.zergpu = True.
In your case, adding the following line after the definition of the run function would fix the second issue.

run.zerogpu = True

If I remember correctly, logged-in users have 300 seconds of quota, so they don't have to subscribe to PRO.

Thanks, let me try it

I have added "run.zerogpu = True", but still this error

The current error is:

Hmm, I see. Thanks for checking. This is the way @cbensimon told me before and it worked back then, but something might have been changed since then. Let's wait for @cbensimon 's response.

Thank you for your great support, looking forward to his reply.

PS: After I restarted the space, "No CUDA GPUs are available" appeared again ...

Oh, weird.
I think it would be great if this Space can run on ZeroGPU, but maybe we can assign L40S with 1 hour sleep time in the meantime if your Space can run on it.

OK, I just switched the hardware to L40S to see if it works.

thanks a lot, let's wait for it to restart. And should we add "run.zerogpu = True" when using L40S?

And should we add "run.zerogpu = True" when using L40S?

No, it should work without it. I doesn't affect normal GPU execution.
Also, spaces does nothing on Spaces with normal GPU, so you don't have to remove the @spaces.GPU decorator either.

The space runs normally (with L40S). It seems that ZeroGPU has some hidden bugs.

Looks like CUDA OOM occurred.

oh, let's try again by adding thes two lines
pipe.enable_model_cpu_offload()
pipe.enable_sequential_cpu_offload()

the space can generate videos normally now, and it seems that only about 19G of gpu memory is needed

Awesome!
Also, thanks for your efforts in debugging the ZeroGPU issues.

Hi @hysts ,
Is the 2ns bug mentioned here solved now? Because i'm facing exactly this situation with my space https://huggingface.co/spaces/filapro/cad-recode

Hi @filapro
No, unfortunately, it hasn’t been fixed yet. I saw some discussions about it internally a few days ago, so as far as I know, it’s still being worked on.
As I mentioned above, you should be able to work around the issue by adding something like wrapper_fn.zerogpu = True to the wrapper function.
I just duplicated your Space and tested, but adding run_test_safe.zerogpu = True fixes the issue for your Space. Can you try that?

Hi @hysts ,
According to your answer I refactored my code, to have less nested functions. Now everything is fine, thanks!
