What is SHARK ?

Shark is an LLMs Backend optimised for Rocm and AMD GPUs that you can use with Blender and Kobold.cpp


Install Shark

Prerequisites - Drivers

Install your Windows hardware drivers

  • [AMD RDNA Users] Download the latest driver (23.2.1 is the oldest supported) here.

  • [macOS Users] Download and install the 1.3.216 Vulkan SDK from here. Newer versions of the SDK will not work.

  • [Nvidia Users] Download and install the latest CUDA / Vulkan drivers from here

Linux Drivers

  • MESA / RADV drivers wont work with FP16. Please use the latest AMGPU-PRO drivers (non-pro OSS drivers also wont work) or the latest NVidia Linux Drivers.

Other users please ensure you have your latest vendor drivers and Vulkan SDK from here and if you are using vulkan check vulkaninfo works in a terminal window

Quick Start for SHARK Stable Diffusion for Windows 10/11 Users

Install the Driver from Prerequisites above

Download the stable release

Double click the .exe and you should have the UI in the browser.

If you have custom models put them in a models/ directory where the .exe is.

More installation notes

  • We recommend that you download EXE in a new folder, whenever you download a new EXE version. If you download it in the same folder as a previous install, you must delete the old *.vmfb files with rm *.vmfb. You can also use --clear_all flag once to clean all the old files.

  • If you recently updated the driver or this binary (EXE file), we recommend you clear all the local artifacts with --clear_all

Running

  • Open a Command Prompt or Powershell terminal, change folder (cd) to the .exe folder. Then run the EXE from the command prompt. That way, if an error occurs, you’ll be able to cut-and-paste it to ask for help. (if it always works for you without error, you may simply double-click the EXE)

  • The first run may take few minutes when the models are downloaded and compiled. Your patience is appreciated. The download could be about 5GB.

  • You will likely see a Windows Defender message asking you to give permission to open a web server port. Accept it.

  • Open a browser to access the Stable Diffusion web server. By default, the port is 8080, so you can go to http://localhost:8080/.

Stopping

  • Select the command prompt that’s running the EXE. Press CTRL-C and wait a moment or close the terminal.

# PYTHON=python3.11 VENV_DIR=0617_venv IMPORTER=1 ./setup_venv.sh

Run any of the hundreds of SHARK tank models via the test framework

Terminal window
python -m shark.examples.shark_inference.resnet50_script --device="cpu" # Use gpu | vulkan
# Or a pytest
pytest tank/test_models.py -k "MiniLM"

How to use your locally built IREE / Torch-MLIR with SHARK

If you are a Torch-mlir developer or an IREE developer and want to test local changes you can uninstall

the provided packages with pip uninstall torch-mlir and / or pip uninstall iree-compiler iree-runtime and build locally

with Python bindings and set your PYTHONPATH as mentioned here

for IREE and here

for Torch-MLIR.

How to use your locally built Torch-MLIR with SHARK:

Terminal window
1.) Run `./setup_venv.sh in SHARK` and activate `shark.venv` virtual env.
2.) Run `pip uninstall torch-mlir`.
3.) Go to your local Torch-MLIR directory.
4.) Activate mlir_venv virtual envirnoment.
5.) Run `pip uninstall -r requirements.txt`.
6.) Run `pip install -r requirements.txt`.
7.) Build Torch-MLIR.
8.) Activate shark.venv virtual environment from the Torch-MLIR directory.
8.) Run `export PYTHONPATH=`pwd`/build/tools/torch-mlir/python_packages/torch_mlir:`pwd`/examples` in the Torch-MLIR directory.
9.) Go to the SHARK directory.

Now the SHARK will use your locally build Torch-MLIR repo.


Benchmarking Dispatches

To produce benchmarks of individual dispatches, you can add --dispatch_benchmarks=All --dispatch_benchmarks_dir=<output_dir> to your pytest command line argument.

If you only want to compile specific dispatches, you can specify them with a space seperated string instead of "All" . E. G. --dispatch_benchmarks="0 1 2 10"

For example, to generate and run dispatch benchmarks for MiniLM on CUDA:

Terminal window
pytest -k "MiniLM and torch and static and cuda" --benchmark_dispatches=All -s --dispatch_benchmarks_dir=./my_dispatch_benchmarks

The given command will populate <dispatch_benchmarks_dir>/<model_name>/ with an ordered_dispatches.txt that lists and orders the dispatches and their latencies, as well as folders for each dispatch that contain .mlir, .vmfb, and results of the benchmark for that dispatch.

if you want to instead incorporate this into a python script, you can pass the dispatch_benchmarks and dispatch_benchmarks_dir commands when initializing SharkInference , and the benchmarks will be generated when compiled. E. G:

Terminal window
shark_module = SharkInference(
mlir_model,
device=args.device,
mlir_dialect="tm_tensor",
dispatch_benchmarks="all",
dispatch_benchmarks_dir="results"
)

Output will include:

  • An ordered list ordered-dispatches.txt of all the dispatches with their runtime

  • Inside the specified directory, there will be a directory for each dispatch (there will be mlir files for all dispatches, but only compiled binaries and benchmark data for the specified dispatches)

  • An .mlir file containing the dispatch benchmark

  • A compiled .vmfb file containing the dispatch benchmark

  • An .mlir file containing just the hal executable

  • A compiled .vmfb file of the hal executable

  • A .txt file containing benchmark output

See tank/README.md for further instructions on how to run model tests and benchmarks from the SHARK tank.
