Hey, finally stable diffusion for ggml 😄

Did a test run

Painpoint: the extra python libs for conversion. Got a pip install error bc i have an incompatible version of something installed already, convert.py worked anyway though. :)

Timings: I used the q8_0 quantization and ran with different thread counts:
I have a 12core(24threads) cpu.
I took the timing of a sampling step.

quant q8_0 q4_0 f16
-t 1 75.31s 75.20s 82.92s
-t 2 42.44s
-t 4 28.65s 29.23s 30.00s
-t 6 21.68s
-t 8 18.34s 18.89s 19.05s
-t 10 16.38s 16.78s 17.61s
-t 12 16.26s 16.98s 18.11s
-t 14 17.93s
-t 16 16.80s
-t 18 16.70s
-t 20 16.20s
-t 22 16.96s
-t 24 18.93s

Additional questions:

  1. do you have/plan to support token weighing? ( eg: (cinematic:1.3) )
  2. are you looking into supporting cuda/opencl backends from ggml?
  3. are you looking into k-quants (like llama.cpp) and some form of quality mesurement of quantizations? (since k-quants use different quant for different parts of the model)
  4. it would be nice if the tool printed the "system line" (see https://github.com/ggerganov/llama.cpp/blob/f64d44a9b9581cd58f7ec40f4fa1c3ca5ca18e1e/llama.cpp#L4267 )
  5. did not see it mentioned, does it support sd 2.x / do you plan to add support for that ?
  6. my little benchmark suggests the bottleneck is not the model file, but the dynamic data. What number type do you use for it, llama.cpp has shown little to no degradation in quality when using f16 instead of f32 for the kv-cache.

edit: added f16 timings

    Thanks for the feedback.

    1. Yes, I'm preparing to support an tokenizer in the style of stable-diffusion-webui, which includes token weighing.
    2. I'm working on adding GPU support and currently focusing on getting ggml_conv_2d to function on the GPU. Because ggml_conv_2d only supports CPU now.
    3. Great idea, I'll add this to the TODO list.
    4. You can add the -v or --verbose parameter, which will allow you to see the system info.
    5. Currently, only SD 1.x is supported. Support for SD 2.x will be added in the future.
    6. Yes, a relatively large amount of memory is being used to store dynamic data (which is actually an optimized outcome). GGML currently utilizes f32 to store temporary calculation results. Changing it to f16 would reduce dynamic memory usage by half. I'm currently contemplating how to modify GGML to achieve this goal.

    very nice

    i see

    oh, i overlooked that one

    the tokenizer really looks like it needs some work, really surprised the image came out that good.

    1. Currently, only SD 1.x is supported. Support for SD 2.x will be added in the future.

    good to hear.

    1. Yes, a relatively large amount of memory is being used to store dynamic data (which is actually an optimized outcome). GGML currently utilizes f32 to store temporary calculation results. Changing it to f16 would reduce dynamic memory usage by half. I'm currently contemplating how to modify GGML to achieve this goal.

    cant wait 😄

    Even with q4_0 the results are pretty good! I got this image with the example prompt:

    Thanks for the feedback.
    Following your advice, I've addressed this issue in the latest commit. This compilation error might have occurred due to differences in compiler implementations. I tested with MSVC and GCC and didn't encounter this problem. May I ask which compiler you are using?

    • What is currently the main performance bottleneck?
      Here is a rough breakdown of the time per op using GGML_PERF:

perf_total_per_op_us[             MUL] =   154.503 ms

perf_total_per_op_us[            GELU] =     4.251 ms
perf_total_per_op_us[            SILU] =     3.978 ms

perf_total_per_op_us[         MUL_MAT] =  1258.711 ms
perf_total_per_op_us[           SCALE] =    47.123 ms
perf_total_per_op_us[            CONT] =   130.151 ms

    Looks like CONV_2D needs some work.

    • Would be nice to upstream the new ggml operators at some point. Not sure about the "dynamic mode" though
    • The "concat" might be possible to achieve via view + cpy

    Thank you for the feedback. Thank you for creating such amazing ggml.

    • Would be nice to upstream the new ggml operators at some point. Not sure about the "dynamic mode" though

    OK, I will sort out the code of new operators and upstream later. I'm also considering whether to upstream the "dynamic mode".

    • The "concat" might be possible to achieve via view + cpy

    I've tried it before，but it seems that combining view + cpy cannot fulfill the concatenation requirement along dim=1.

    unsurprisingly it takes way (way) longer:

    Wow, this is so cool. Easy to convert existing models, quantization.. very nice.

    https://github.com/bes-dev/stable_diffusion.openvino <- this is way faster though, probably due to it using OpenVINO.

    1. my little benchmark suggests the bottleneck is not the model file, but the dynamic data. What number type do you use for it, llama.cpp has shown little to no degradation in quality when using f16 instead of f32 for the kv-cache.

    I've implemented a memory optimization, and now when using txt2img with fp16 precision to generate a 512x512 image, it only requires 2.3GB.

    Oh, yeah. Now I'm working hard to make it run faster.

    I've implemented a memory optimization, and now when using txt2img with fp16 precision to generate a 512x512 image, it only requires 2.3GB.

    is this already on master? bc i reran my diffusion above with similar timings and memory usage (? memory reporting changed)

    Since you are generating 768x768 images, this will cause the runtime memory to grow, and there is still room for optimization
