*** FOR THOSE THAT ARE GETTING TROJAN DETECTIONS IN NCCL.DLL IN ZLUDA FOLDER, in dev's words : " nccl.dll is a dummy file, it does nothing. when one of its functions is called, it will just return "not supported" status. nccl.dll, cufftw.dll are dummy. they are introduced only for compatibility (to run applications that reject to start without them, but rarely or never use them).zluda.exe hijacks windows api and injects some dlls. its behavior can be considered as malicious by some antiviruses, but it does not hurt the user.
|
||||
The antiviruses, including windows defender on my computer, didn't detect them as malicious when I made nightly build. but somehow the nightly build is now detected as virus on my end too. " SO IGNORE THE WARNING AND MAYBE EXCLUDE THE ZLUDA FOLDER FROM DEFENDER.

*** QUICK INSTALL INSTRUCTIONS : "https://github.com/patientx/ComfyUI-Zluda/issues/188"
|
||||
|
||||
## What's New?
|
||||
|
||||
* Updated zluda version for old install method and for old amd devices to 3.9.5 (latest) because the newer amd gpu drivers are having problem with old zluda versions. For newer users this wouldn't be a problem but if you already had comfyui-zluda installed (via the older method) and want to re-install the app , please delete everything in : "C:\Users\yourusername\AppData\Local\ZLUDA\ComputeCache" so new zluda can create its database from scratch.
|
||||
* Added "cfz-vae-loader" node to cfz folder, it enables changing vae precision on the fly without using "--fp16-vae" etc. on the starting commandline. This is important because while "wan" works faster with fp16 , flux produces black output if fp16 vae is used. So, start comfy normally and add this node to your wan workflow to change it only with that model type.
|
||||
* Use update.bat if comfyui.bat or comfyui-n.bat can't update. (as when they are the files that needs to be updated, so delete them, run update.bat) When you run your comfyui(-n).bat afterwards, it now copies correct zluda and uses that.
|
||||
* Added two workflows for wan text to video and image to video. They are on CFZ folder. From now on I will try to share other workflows that works good on zluda at least on my setup, it could be a starting point for new users if nothing else. Text-to-video has some notes please read them.
|
||||
* Updated included zluda version for the new install method to 3.9.5 nightly aka latest version available. You MUST use latest amd gpu drivers with this setup otherwise there would be problems later, (drivers >= 25.5.1) """ WIPE THE CACHES , READ BELOW """ I recommend using "patchzluda-n.bat" to install it , it uninstalls torch's and reinstalls and patches them with new zluda.ALSO you need to uninstall hip 6.2.4 completely, delete the folder , and reinstall it and again download and unzip the NEW Hip addon (this is not the same as the one I shared before , this is new for 3.9.5) for this 3.9.5 version (hopefully this won't happen that much) new hip addon for zluda 3.9.5 : (https://drive.google.com/file/d/1Gvg3hxNEj2Vsd2nQgwadrUEY6dYXy0H9/view?usp=sharing)
|
||||
* WIPING CACHES FOR A CLEAN REINSTALL :: There are three caches to delete if you want to start anew -it is recommended if you want a painless zluda experience : 1-) "C:\Users\yourusername\AppData\Local\ZLUDA\ComputeCache" 2-) "C:\ Users \ yourusername \ .miopen" 3-) "C:\ Users \ yourusername \ .triton" , delete everything in these three directories, zluda and miopen and triton will do everything from the start again but it would be less painful for the future.
|
||||
* Added "CFZ Cudnn Toggle" node, it is for some of the audio models, not working with cudnn -which is enabled by default on new install method- to use it just connect it before ksampler -latent_image input or any latent input- disable cudnn, THEN after the vae decoding -which most of these problems occur- to re-enable cudnn , add it after vae-decoding, select audio_output and connect it save audio node of course enable cudnn now.This way within that workflow you are disabling cudnn when working with models that are not compatible with it, so instead of completely disabling it in comfy we can do it locally like this.
|
||||
* "CFZ Checkpoint Loader"was broken, it might corrupt the models if you load with it and quit halfway, I completely redone it and it now works outside the checkpoint loading so doesn't touch the file and when it does quantize the model, it makes a copy and quantizes it. Please delete the "cfz_checkpoint_loader.py" and use the newly added "cfz_patcher.py" it got three seperate nodes and much safer and better.
|
||||
* BOTH of these nodes are inside "cfz" folder, to use them copy them into custom_nodes, they would appear next time you open comfy, to find them searh for "cfz" you will see both nodes.
|
||||
* flash-attention download error fixed, also added sage-attention fix, especially for vae out of memory errors that occurs a lot with sage-attention enabled. NOTE : this doesn't require any special packages or hardware as far as I know so it could work with everything.
|
||||
* `install-n.bat` now not only installs everything needed for MIOPEN and Flash-Attention use, it also automates installing triton (only supported for python 3.10.x and 3.11.x) and flash-attention. So if you especially have 6000+ gpu , have HIP 6.2.4 and libraries if necessary, try it. But beware, there are lots of errors yet to be unsolved. So it is still not the default installed version.
|
||||
* If you want to enable MIOPEN , Triton and Flash-Attention use the install-n.bat . This will install torch 2.7 , with latest nightly zluda and patch the correct files into comfyui-zluda. This features do not work very well and you are on your own if you want to try these. (---- You have to install HIP 6.2.4 - Download and extract HIP Addon inside the folder (information down below on installation section). ---)
|
||||
* Python libs are copied automatically now, so triton compilation errors should be gone on startup. Also triton and torch patches are applied on install thanks to `https://github.com/sfinktah`
|
||||
* Updated included zluda version for the new install method to 3.9.5 nightly aka latest version available. You MUST use latest amd gpu drivers with this setup otherwise there would be problems later, (drivers >= 25.5.1) """ WIPE THE CACHES , READ ON TROUBLESHOOTING BELOW """ I recommend using "patchzluda-n.bat" to install it , it uninstalls torch's and reinstalls and patches them with new zluda.ALSO you need to uninstall hip 6.2.4 completely, delete the folder , and reinstall it and again download and unzip the NEW Hip addon (this is not the same as the one I shared before , this is new for 3.9.5) for this 3.9.5 version (hopefully this won't happen that much) new hip addon for zluda 3.9.5 : (https://drive.google.com/file/d/1Gvg3hxNEj2Vsd2nQgwadrUEY6dYXy0H9/view?usp=sharing)
|
||||
* Florance2 is now fixed , (probably some other nodes too) you need to disable "do_sample" meaning change it from True to False, now it would work without needing to edit it's node.
|
||||
* Added onnxruntime fix so that it now uses cpu-only regardless of node. So now nodes like pulid, reactor, infiniteyou etc works without problems and can now use codeformer too.
|
||||
* Added a way to use any zluda you want (to use with HIP versions you want to use such as 6.1 - 6.2) After installing, close the app, run `patchzluda2.bat`. It will ask for url of the zluda build you want to use. You can choose from them here,

If coming from the very start, you need :
|
||||
* Do everything one by one, do not skip. *
|
||||
|
||||
1. **Git**: Download from https://git-scm.com/download/win.
|
||||
During installation don't forget to check the box for "Use Git from the Windows Command line and also from
|
||||
3rd-party-software" to add Git to your system's PATH.
|
||||
2. **Python** ([3.11.9](https://www.python.org/ftp/python/3.11.9/python-3.11.9-amd64.exe)) version "3.11" . (I no longer am suggesting 3.10 as default since a lot of newer stuff is only coming out in 3.11 and up. 3.10 still works but you may encounter a package that specifically needs 3.11 , so for new installs I suggest using 3.11) Install the latest release from python.org. **Don't Use
|
||||
Windows Store Version**. If you have that installed, uninstall and please install from python.org. During
|
||||
installation remember to check the box for "Add Python to PATH when you are at the "Customize Python" screen.

## Troubleshooting

|

- Use update.bat if comfyui.bat or comfyui-n.bat can't update. (as when they are the files that needs to be updated, so delete them, run update.bat) When you run your comfyui(-n).bat afterwards, it now copies correct zluda and uses that.

|
||||
- Problems with triton , try this : Remove visual studio 2022 (if you have already installed it and getting errors) and install "https://aka.ms/vs/17/release/vs_BuildTools.exe" , and then use "Developer Command Prompt" to run comfyui. This option shouldn't be needed for many but nevertheless try.
|
||||
- `CUDA device detected: None` , if seeing this error with the new install-n , make sure you are NOT using the amd driver 25.5.1 . Use a previous driver, it has problems with zluda.
|
||||
- `RuntimeError: CUDNN_BACKEND_OPERATIONGRAPH_DESCRIPTOR: cudnnFinalize FailedmiopenStatusInternalError cudnn_status: miopenStatusUnknownError` , if this is encountered at the end, while vae-decoding, use tiled-vae decoding either from official comfy nodes or from Tiled-Diffussion (my preference). Also vae-decoding is overall better with tiled-vae decoding.
