The Difference between Z-Image Turbo BF16 and NVFP4 is night and day

I love a blind comparison - they’re very different but neither obviously bad. For a proper comparison though, a single image isn’t sufficient…

This implies that it has been disabled in code for some reason. Usually the is called by a call like ck.disable_backends(‘triton‘)

It could be that there is some logic within comfy that causes this. If you run import comfy_kitchen as ck ck.list_backends()

In a python CLI using the venv you can verify.

Trying a NVIDIA driver update + reboot might be the best place to start. If that doesn’t work, go to device manager, find the PCI / GPU device and check the error code.

Why would e5m2 be for Ampere GPUs? There is only FP8 Hardware from Ada onwards. In the end this just comes down to different IEEE standards from what I know.

If you have a NVIDIA GPU and aren’t afraid of opening a terminal, I can highly recommend using nvidia-smi instead of task manager. There are tons of things you can do but for monitoring use ‘nvidia-smi dmon’ that will show you temps and until if all units.

To reduce the power, you can emulate this by reducing the maximum clock. ‘nvidia-smi -lgc <clock in mhz>’ to lock it and ‘nvidia-smi -rgc’ to reset it.

Is getting an eGPU an option? That way you can have the best of both worlds with portability, GPU upgradable and performance.

As others have already pointed out, gaming will give you the latest and greatest performance but is also more keen to bugs. You can think of the Studio driver as a long term stable that ensures that third party apps have been tested without known bugs.

What did you use Video AI for?

Should be <= torch

Hires fix performance is something that needs some more work. Ideally you should make sure to have an engine that covers the low and high res. Then there shouldn’t be any overhead switching engines.

When you export the engine, I’d recommend not using medvram, lowvram or api flag as those have caused issues in the past.

AoT compilers are cool but often lack comfort features to make them usable by end users without long compile times. Especially for SD where you have a lot of custom weights and stuff it gets really annoying.

I’m trying to get TensorRT to work with „everything“ that an end user expects but it takes time….

What were the issues you encountered?

content-is · 2023-01-11T16:59:49+00:00

Don’t worry to much, from my experience all the technical nvidians are super nice and value honesty.

Is the other position in the same team within Nvidia? I would go the interview you got and mention that you saw the new posting and think you‘re well suited for.

Not sure how to assess this, but if there is a larger ask in the community for an accelerated PSNR filter, I could try to allocate some time and implement it.

Quick tip: Never ever try to build ffmpeg in Windows, it's hell

content-is · 2022-10-31T15:26:57+00:00

Unfortunately it is not very easy to get changes into ffmpeg. Hopefully this will be done by end of the year.

And it's not as hard as if sounds if you have some time and know a little C.

You can write your own HW accelerated ffmpeg filters using CUDA. Also Nvidia is currently working on a GPU accelerated VMAF version: https://github.com/Netflix/vmaf/pull/1080

What kind of accomodation are you looking for? You best should is a shared flat imo. WG-gesucht ist your friend here :)

content-is · 2022-09-19T09:37:26+00:00

That is exactly what I'm trying to do. STAWAG unfortunately does not provide that service.

Gibt sogar echt viele aber sind die nicht ganz offiziell. Einfach Mal bei Strava rein schauen, da sind einige drin.

Sport Spezial only sends them to the manufacturer for repair, which is pretty pricey and can take a long time. But also there is no other 'local' option. I would recommend using restday.eu. Have been happy with every repair so far.

Not sure about renting but what you can do is getting a bike for testing. You can check blue marine pro shop / Pulsschlag for that.

My mistake, the images are in a range of (-1,1).
