Update readme.md with macOS installation instructions

[jorge-campo]

Adds specific Mac M1/M2 installation instructions for Fooocus.

The same instructions for Linux work on Mac. The only prerequisite is the PyTorch installation, as described in the procedure.

On my M1 Mac, the installation and first run ran error-clean, and I could start generating images without any additional configuration.

[ponymushama]

macOS does not have conda command.
Should install conda at first.

[dreamscapeai]

how many it/s can you have on the M1 pro ?

[jorge-campo]

macOS does not have conda command.
Should install conda at first.

If you follow the Apple technical document in the procedure, it will instal miniconda3 from the Anaconda repo.

[jorge-campo]

how many it/s can you have on the M1 pro ?

In my case, these 👇 are the statistics for the Base model + Refiner for two images using the same prompt. My computer has many other processes running in the background competing for RAM, so your mileage may vary.

[lllyasviel]

wow 8s/it - that is quite a bit waiting

[jorge-campo]

wow 8s/it - that is quite a bit waiting

Yes, it is, but it's similar to what I get with ComfyUI or Automatic1111 using SDXL; SD1.5 is faster though. I don't think you can do better with M1 + SDXL (?)

I don't know what optimizations you included in Fooocus, but the image quality is vastly superior to ComfyUI or Automatic1111. Thanks for giving us the chance to play with this project! 😄

[thinkyhead]

Note that once Miniconda3 is installed and activated in the shell, the Linux instructions work perfectly on macOS.

[guo2048]

After I install it locally with your steps, I got the same issue like described here. #286
the two result pictures are just empty pictures.

[eyaeya]

It looks like I'm running into a problem with the environment, how can I get past this? I didn't see the instructions for this part in your Readme.

File "/Users/xiaoxiao/Pictures/Fooocus/modules/anisotropic.py", line 132, in adaptive_anisotropic_filter s, m = torch.std_mean(g, dim=(1, 2, 3), keepdim=True) NotImplementedError: The operator 'aten::std_mean.correction' is not currently implemented for the MPS device. If you want this op to be added in priority during the prototype phase of this feature, please comment on https://github.com/pytorch/pytorch/issues/77764. As a temporary fix, you can set the environment variablePYTORCH_ENABLE_MPS_FALLBACK=1 to use the CPU as a fallback for this op. WARNING: this will be slower than running natively on MPS.

@jorge-campo

[kjslag]

I had to launch with PYTORCH_ENABLE_MPS_FALLBACK=1 python launch.py insead of python launch.py to deal with the same issue that @eyaeya had. After that, it ran with about 2.7s/it on an M1 Max macbook pro. But the output was just a blank color. I used the latest (as of now) Fooocus commit 09e0d1c from Sept 2 2023.

[iwnfubb]

Works like a charm ! Is it normal the program just use too much RAM ~ 20GB is used ?

[jorge-campo]

Please refer to the macOS installation guide in the README.md file.

Hi! I'm a cpmplete noob to this. I'm using macbook pro m1 pro 16 gb and it takes around an hour to generate one image. Am I doing something wrong or is it just because I'm using mac? It also has an error that has been discussed here previously (The operator 'aten::std_mean.correction' is not currently supported on the MPS backend and will fall back to run on the CPU.), does it affect the waiting time?

Apple M1 Pro Sonoma 14.1.12

@Zeeshan-2k1 did you solve your issue? I had the exact same error shown. In my case, I had already a newer version of python (3.12) installed, with a link to it, so whenever I was doing commands with "python" it was linked to the newer version of course. However, when you follow the steps in the readme, it will install python 3.11 for you and you have to use this python also, as libraries such as pygit2 are installed in that framework as well (within Conda). Hope this helps!

[mariitz]

I was testing some combinations of all the parameters, however, long story short, the best for me (MacBook Pro, M3 Pro apple silicon) was: python entry_with_update.py --attention-pytorch

So the --attention-pytorch did the most performance boost, going from 25-30 secs. per iteration, down to almost 5secs/it. Further, I still included --always-high-vram --disable-offload-from-vram, however I am still not 100% sure if there is any difference in my case noticeable. Almost the exact same results, in terms of timing.

Also the newest version of Fooocus (web UI) allows you to choose for extreme speed setting (when selecting "Advanced"), where only 8 iterations per image are needed. By selecting so, you might create the images even faster, of course, with a slight quality decrease.

[nicksaintjohn]

Just to clarify for anyone else reading this thread. I can confirm that there is a speed-memory issue at 16Gb using the Mac M-series. You need to force 16-bit floating point, to reduce memory just enough to avoid a bottleneck. This will over double the speed... I went from over 120 it/s, down to <60 it/s. Still not fast, but it becomes usable.

I usually run with python entry_with_update.py --all-in-fp16 --attention-split but, tbh, I don't think the attention-split helps (still testing)

[Deniffler]

python entry_with_update.py --all-in-fp16 --attention-split,

Thanks bro!
I've tried all the variations of the startup commands. At first I had 100-110 sec/it , but your prompt was able to speed up the process to 5-7 sec/it !!!!
I have a MacBook Pro, M1 Pro, 16Gb, year 2021

[Deniffler]

For optimize the execution of your command in the command line and potentially speed up the process, we can focus on the parameters that most affect performance. However, given that your command already contains many parameters for optimizing memory and computational resource usage, the main directions for improvement may involve more efficient GPU usage and reducing the amount of data required for processing in each iteration.

Here's a modified version of your command considering possible optimizations:

python entry_with_update.py --all-in-fp16 --attention-pytorch --disable-offload-from-vram --always-high-vram --gpu-device-id 0 --async-cuda-allocation --unet-in-fp16 --vae-in-fp16 --clip-in-fp16

Explanation of changes:

Removed unsupported parameters: Parameters that caused an error due to their absence in the list of supported script parameters (--num-workers, --batch-size, --optimizer, --learning-rate, --precision-backend, --gradient-accumulation-steps) have been removed.

Clarification of FP16 usage: Explicit indications for using FP16 for different parts of the model (--unet-in-fp16, --vae-in-fp16, --clip-in-fp16) have been added. This suggests that your model may include components like U-Net, VAE (Variational Autoencoder), and CLIP. Using FP16 can speed up computations and reduce memory consumption, although it may also slightly affect the accuracy of the results.

Using asynchronous CUDA memory allocation: The --async-cuda-allocation parameter implies that the script will use asynchronous memory allocation, which can speed up data loading and the start of computations.

Additional tips:

Performance analysis: Use profiling tools to analyze CPU and GPU usage to identify bottlenecks.
Data loading optimization: If possible, optimize data loading to reduce IO wait times. This can include using faster data formats or buffering data in memory.
Library version checks: Ensure you are using the latest versions of all dependencies. Sometimes updates contain significant performance improvements.
Experiments with batch size: Although the --batch-size parameter is not supported by your current command, if there's an opportunity to adjust the batch size in the code, it can significantly impact performance. Larger batch sizes can increase performance at the expense of increased memory usage.
Remember, performance optimization often requires experimentation and fine-tuning, as the impact of changes can greatly depend on the specific details of your task and hardware.

Thank you, got it down to around 13-14 s/it on 2020 M1 MacBook Air 16GB. It starts with 10.5 tho, and slows down after a couple of steps. Fooocus still runs a bit slower than A1111 (7-8 s/it), but IMO still usable. I think it could be faster if it used both CPU and GPU cores. For now, it sits on about 96% with frequent dips to 80% GPU and only 10-17% CPU. Any way to change that? I want my whole machine to generate.

[nicksaintjohn]

Great work @Deniffler, you clearly spent more time and effort than I have, I was just glad to get it running fully off the GPU... Very glad that I helped set you on the right path, as you've now got us all running as past as possible. I'm much more productive now, many thanks.

[tjex]

Posting here as described should be done. Can convert to an issue later if necessary.

The image input checkbox does not reveal the image input tabs / parameters for me.
And the prompt text box is huge...

On my fork I found the rows for the prompt box was set to 1024 and image_input_panel was hidden. The hidden panel could make sense considering the check box is probably what opens the panel? But the prompt box set to 1024 is odd.

It would also seem that image prompting is not working at all for me. I check "image prompt", place in two images (a landscape and an animal) and click generate. Fooocus then generates a random portrait image of a man/woman.

However, if I put an image into the describe tab, and click describe, it will indeed create a prompt from the image. So the tab/image handling seems to be working at least?

Anyone else having a similar problem?

[deathblade287]

@samerGMTM22

Step 1 : Create a .sh file with the command python entry_with_update.py (or whatever version of it you use).

Step 2 (Option 1) : Follow this answer to convert it into a .app that you can then run as you would run any other app on mac os.

Step 2 (Option 2) : Select that file as one of the "login items" in your setting. Note that this way the server will always run in the background.

The operator is not yet supported by Apple, that's all. You can (want to) tinker with it as much as you want.
--disable-offload-from-vram only shortens the loading of the model, but has no effect on the lack of support for the pytorch operator aten::std_mean.correction.

Der Operator wird bis dato nicht von Apple unterstützt, dass ist alles. Da kann man noch so viel rumschrauben (wollen) wie man will.
--disable-offload-from-vram verkürzt nur das Laden des models, aber hat keine Auswirkungen auf die fehlende Unterstützung für den pytorch-operator aten::std_mean.correction.
