I am currently stuck due to a problem: I have a ROCm compatible AMD graphics card and I have been using ComfyUI with a nix shell so far, using the In this package and service, I made sure the default However, when I try to build the derivation using I also tried switching to using It looks like the problem is that it's trying to put different versions of torch into the same python environment. I then tried manually overriding all the python deps that use torch so that they would use the torch provided to the comfyui package.

Hi, I'm the person behind most of the ROCm stuff on nixpkgs nowadays.
Can't believe we're already at this point, great work!
There's a few problems though, mostly outlined in the comments below.
The ROCm version is likely not working because it needs torchvision and torchaudio to be the ROCm variants. https://github.com/comfyanonymous/ComfyUI#amd-gpus-linux-only
From what I can tell, there's no setup.py or pyproject.toml in the project, which is irritating because then we could add this to python-packages instead. I'm unsure if there's a better alternative than what you're currently doing in this PR. See: #268378 (comment) and #268378 (comment)
I may be missing some things, but overall aside from the things I've commented on, it looks good!

Many of the torch-related packages here likely need rocm variants.
There was a problem hiding this comment.
yes, off the top of my head I think torchsde, torchvision, torchaudio, transformers, safetensors, accelerate all depend on torch and therefore they need some kind of rocm variant.
I have tried doing an override on them here, to pass the correct torch reference, but it didn't seem like the right way to do it.
I am thinking that we either need to declare a variant for each one like we do for torch, or I will need to do an override here and pass the appropriate gpuBackend. However I am not sure which one I should do

That wouldn't be too hard, would simplify a LOT of things, and would actually make this PR simpler since we could just put comfyui under pkgs(Cuda|Rocm).
Anyway, I think it's unreasonable to ask that every package that depends on torch declare two variants.
Why is it so? To make hydra build and cache both version? Aren't both unfree and thus not cached anyway?

But yeah, otherwise I don't see much point in those attributes. Personally, I only use nix (build|run) -f '<nixpkgs>' --arg config '{ cudaSupport = X; rocmSupport = Y; }' ..., instead of the xWithY attributes

This is in a place that's ready for re-review, and assistance. A rebase has been done that makes it current as of 2024-05-22. I do have a few misc TODO items to handle, but nothing that keeps it working in its present state. I have seen locally the same problem listed in the build, and my only fix for it was to disable the man pages. This seemed to start after the rebase was complete. I don't know what caused it, and nothing about the error has given me leads to investigate. The problem even manifested when I took out comfyui usage from my local configuration. I've done some searching around and haven't found anyone else with the problem. I'm currently using While I am happy to continue working on this, I can't get any further without some guidance (aside from my unrelated TODO items). |

Regarding pytorch-bin: we should abstain from referring to pytorch-bin directly and from using ad hoc overrides like that. Instead, we should consistently refer to Nixpkgs' attributes, so that users can expect their overlays to actually have effect.
If a particular user decides to use pytorch-bin they'll just import nixpkgs with something like { overlays = [(final: prev: { pythonPackagesExtensions = [ (py-fin: py-pre: { torch = py-fin.pytorch-bin; }) ]; })];

Thanks! Yes this is the guidance I was looking for because I knew it was wrong. I'll give this a try and see if it still works for me.

Hmm, this hasn't worked for me in the end. I've spun my wheels quite a bit on getting this working. Currently I'm stuck on this when using this with pytorch-bin / torch-bin as above:
error: function 'anonymous lambda' called with unexpected argument 'cudaSupport'
at /nix/store/c7xdr8fi9vbjmp2srk61cidhc9azb9yf-source/pkgs/development/python-modules/torch/bin.nix:1:1:
And building torch just remains out of reach for me. The exact error seems to vary based on my exact commit of nixpkgs I'm using. It almost looks like a hardware error, but I've exercised the machine more consistently and extensively than by building torch (such as actually using it). The build machine has 32 GB of ram and it's only used about 200 GB of its total 1 TB of disk. Some advice suggests resource exhaustion.
I'm kind of stuck on this. I'll keep trying things.
FWIW I periodically rebase atop master so at least I'm not chasing last month's fixed bugs.

I'm a bit lost, what exactly is the purpose of this? Why not call fetchurl directly?
There was a problem hiding this comment.
I neglected to document this, and will do so next chance I get to do some work on it. ComfyUI cares about the file names - particularly the extensions. It goes off of that to know how to handle the file. When doing a pure fetchurl on the file, Nix was storing the file with its name being the hash. Much of the model handling is about that, but also to leave files in your store that you could have some idea what they were about. I also noted that needing some sort of auth token was frequently required for a lot of models in various places, so that's where the bearerFile stuff comes in.
I'm not particularly attached to the approach, and it's possible I've missed some handy helpers or patterns in the process. It's also possible my findings were due to some bungle that I've fixed along the way.
There was a problem hiding this comment.
I'll try to stick to this thread now.
ComfyUI cares about the file names - particularly the extensions
I see. Canonicalizing names ad hoc like you do is surely one way to go. Ideally we'd want this canonicalization scheme to be stable (as in, we'd rather choose one and never change it). An alternative could be to use plain fetchurl and then symlink the artifacts in a separate derivation.
need ... some sort of auth token
It appears that bearer-based authentication support in fetchurl is something that already came up outside this PR (e.g. https://discourse.nixos.org/t/how-to-fetchurl-with-credentials/11994). I think it may be a bit out of scope for this PR to be taking care of this: this probably belongs in fetchurl itself, and the comfyui code should better be oblivious as to whether fetching the artifact involved any authentication.
Maybe we should have a closer look at this and open a tracking issue
This would be a path to the file, so it wouldn't be in your Nix store
Note that this would require special configuration on the host side, like extra-sandbox-paths.
Is there a general pattern established on how to get files named from fetchurl?
Note that custom names affect hashes too.
There was a problem hiding this comment.
Apologies if I'm being overly verbose/pedantic: It sounds like you're saying we shouldn't be trying to store a derivation by any kind of filename since changing the filename (an immaterial aspect of the file from Nix's perspective) causes a re-download and duplicate storage of the file - thus we should not do that. Is that correct?
I'm fine with that if it's the case, and the filename symlinked in the end is the only thing we care about.
I am happy to remove this utility entirely, and simply suggest in documentation how one might use a bearer token. I'd come across the netrc stuff before (in that very post I think) - it may be my ignorance but it seemed like a less ideal way to go about handling a sensitive token, especially when there may be multiple of them needed. I'm using agenix-rekey to manage my secrets currently but I understand not everyone can/should do that.

@lboklin I don't know how closely you've been tracking the work here but this is a noteworthy deviation from the prior interface.
There was a problem hiding this comment.
I admit I've been sort of tunnel-visioning and doing my own thing. I only recently added some custom nodes from this PR, but otherwise my implementation is diverging a fair bit.
I deviated from the original interface along the way as well.
I flattened the hierarchy, turned the attribute-based install path heuristic into an installPath attribute of the model, and instead of using namespacing I added model type (and base model) as extra attributes to enable filtering (if a bit more involved than tab-completing in the repl).
One problem is that fetchurl (IIRC both the one in builtins and <nix/fetchurl.nix>) would fail to automatically derive a proper name based on some civitai urls (they use url basename, which (are not only useless for civitai urls but) includes illegal characters like ?), so name had to be explicitly passed in. Does fetchurl here not have that problem?

Indeed, but some sites require an auth token. This would be a path to the file, so it wouldn't be in your Nix store. I should document this better though. I'm also open to better approaches.

This isn't used anywhere else, so Torch isn't getting compiled with CUDA and comfyui crashes at startup. Is there something blocking this?

This may be vestigial, but I'm not sure. I have older code doing things like using torchWithCuda if the gpuBackend is "cuda" for example. I don't think that's right, because then you can't override your own torch (like via torch-bin). This is a place where contributor documentation/advice could use some help.

Hi! I just want to mention that this is quite a hefty (almost overwhelming 🙃) PR and personally I haven't even got around to read most of the diff. There is a lot to review if we wish to ensure that this is maintainable and will actually stay in Nixpkgs long-term. I would like this PR to see its logical conclusion, and to be honest I think that you'd speed the process up if you split this into smaller chunks (e.g. a PR for the package, a PR for the module)

I think we should use the finalAttrs pattern here.
The finalAttrs pattern will let you remove the rec keyword (see its implementation in Nix).
Why is this pattern preferred to rec ?
Let's take this simple code example:
mkDerivation rec {
foo = 1;
bar = foo + 1;
}and then .overrideAttrs(old: { foo = 2; }), you'll get { foo = 2; bar = 2; } while with finalAttrs pattern, it would work correctly because it's a real fixed point.
Let me share a couple of useful links regarding the finalAttrs pattern:
- History: https://discourse.nixos.org/t/avoid-rec-expresions-in-nixpkgs/8293
- Documentation: https://nixos.org/manual/nixpkgs/unstable/#mkderivation-recursive-attributes

It is still available for some time as part of rocmPackages_5.I believe rocm was updated to version 6 earlier this year, and I believe this means that rocm 5 support has been dropped in my version of Nixpkgs? |

@Azeirah this works: nixified-ai/flake#94 |

@Azeirah from my end this is presently on pause. There's a few review items left, some trivial and some potentially large. It's also been requested to move this into two separate PRs. None of the asks are unreasonable but I don't have means of testing rcom support but that may change in the next few weeks. That said, your problem there seems more related to rcom than anything the comfyui Nix package is doing. If you believe that to be incorrect, then I'd need more info to go off of until I am able to test on my own hardware. |

I've been able to run comfyui itself with both this package as well as the flake you mentioned, but I'm unable to get either to work with rocm. I do have llama.cpp running using their flake with rocm, so at the very least I know nix + rocm is possible. I do understand that llama.cpp uses rocm directly, and doesn't depend on pytorch however. I'm still trying to get this to work with rocm, but it's difficult. The python311packages has a I can add @Madouura Do you have any suggestions for getting pytorch rocm to work with this project as-is? What confuses me is that I think this set-up is using rocmPackages_5, right? In rocmPackages/5/ there is a miopengemm folder, in rocmPackages/6/ there is not. So I think this error comes from somehow using rocmPackages/6? I don't quite understand if the path in nixpkgs |
Description of changes
This adds ComfyUI, an advanced Stable Diffusion web based UI. Fixes #227006
I plan to also add a service to be able to configure this properly.This PR includes a service for running the web app plus a system to manage "custom nodes" which are ComfyUI plugins, and packages one that I use.ComfyUI does not do versions, so
I am using the commit hash as versionI am setting the version as recommended by @rnhmjoj.Things done
Due to having to buildtorch, the build takes very long. I plan to let this build tomorrow while I am not using the computer then fix any issues with the derivation after that.I changed base so I could leverage the package cache and got it to build and run. I also tested the service.
Some very recently merged developments allow this to automatically run with CUDA or with ROCm support depending on the
nixpkgsconfiguration, however I am trying to detect that so I can automatically run this with--cpuin case both are off, otherwise it crashes on startup.On
aarch64-darwinComfyUI can leverage Apple's build oftorchto use the hardware acceleration (similar to CUDA and rocM) but I am not sure if torch is packaged properly for this on darwin.nix.conf?
