Hi @perler thanks for your interest in ZeroGPU. Official documentation will come at some point but in the meantime I'll try to accurately answer your questions

1. 5 minutes is the maximum time that can be requested at once
2. Quotas are only applied to visitors, they do not depend on the Space. As a Space author you are subject to the same quotas than arbitrary visitors
3. Quotas have a half-life of 2h. It means that what you used count half after 2h (precision is of course down to the second)
4. For now you need to catch the exception. We might display quotas on the hub one day (let me know if you think that it would be an important feature)
5. We currently do not have mechanisms for doing this (if your attendees do not connect on the same WiFi and use their own mobile connection you shouldn't have quota issues. You get it, quotas are IP-based)

@cbensimon thank you! That already helps a lot.

I have a few more questions, this time more spaces-related:

1. How large is the pool of GPUs for Zero-GPU roughly? All A10g?
2. Is there documentation of the HF Spaces backend? E.g. concerning
   1. available hardware,
   2. drivers,
   3. settings,
   4. default environment variables,
   5. shared hard drive,
   6. virtualization,
   7. backend package versions, e.g. docker
3. I can test most commits locally with my own docker setup. But Spaces has some quirks that I can only work out with trial-and-error. A development system for quicker building and testing would be great. One example: I tried calling my NN reconstruction directly within Python from the main process. Spaces didn't allow me to spawn the worker processes for the data loader. "daemonic processes are not allowed to have children". I guess that makes sense but there is no way, I would have tested that before pushing.

Anyway, thank you for HF. It surely helps with getting academic results to the people.

1. ZeroGPU recently migrated to Nvidia A100 and runs on a couple hundreds of them
2. No official documentation for now. Your Space runs in a containerized environment but specs are not stabilized at the moment
3. "daemonic processes are not allowed to have children" --> Probably comes from the fact that @spaces.GPU is effect-free outside of a real ZeroGPU Space environment, so you don't get the error in your dev environment (the function is just called, while it is run in a subprocess on ZeroGPU). We'll soon disable daemon=True on ZeroGPU workers as well as provide a local ZeroGPU emulation mode (very basic but still should allow catching a lot more errors)

Anyway, thank you for HF. It surely helps with getting academic results to the people.

Thank you for this 🤗

thanks!

very grateful for the opportunity!

I have a few questions:

1. ...you write that the maximum time is 5 minutes, but processes running on zero gpu for more than a minute are terminated with an error - how can we use at least part of these conditional 5 minutes?

• I see my task in experiments with generative neural network settings and a few extra minutes of calculations will greatly advance this work.

2. ...only 10 spaces per 1 account

• I understand 10 public spaces running 24/7, but who would be bothered by sleeping private spaces?
  ...there are a lot of neural nets in my project and I have to delete spaces to try them out

3. Can't you do something about the overall design? (for example)

• a common panel for starting and stopping spaces, indication of workability
• a loading indicator for public spaces
• project design options
• statistics of using your spaces
• permanent storage of test images from projects together with settings (something like a notebook inside the system).

About 1.:
You can specify the estimated duration in the GPU decorator, e.g. this for 3 minutes

@spaces.GPU(duration=60 * 3)
def run_on_gpu(...)
   ....

Don't know about the other questions.

1. Will be soon documented but yes, @perler answered right, thanks for this!
2. Sure, for now we took very simple measures to prevent mass abuse but yes it will be more fine-grained in the future (like having different limits for sleeping vs. alive ZeroGPU Spaces)
3. We're working actively on making Spaces a better platform for the community. Taking your ideas as feedbacks! (Space statistics already exist at the very bottom of the Settings tab)
   (by the way if you can elaborate on "a loading indicator for public spaces", I'd be curious @PandaArtStation )

(by the way if you can elaborate on "a loading indicator for public spaces", I'd be curious @PandaArtStation )

The idea is roughly as follows:

• Take a model for generating pictures, experiment with settings and various additions, and put it out into the public domain after the testing phase is complete

...To understand how interested users are in this modification of the basic model, we need statistics of its use and something like a microforum specifically for this space.

To understand how interested users are in this modification of the basic model, we need statistics of its use
We'll soon have public statistics (total GPU runs, total GPU seconds) on ZeroGPU!

Has ZeroGPU moved to A10G spaces?

It’s now A100
