1.2 Source-free Installation#

# Note: First install PyTorch, then execute the following commands
python3 -m pip uninstall -y triton  # Repeat the cmd until fully uninstalled
RES="--index-url=https://resource.flagos.net/repository/flagos-pypi-hosted/simple"
python3.11 -m pip install flagtree===0.7.0+ascend3.5 $RES

2. Build from Source#

2.1 Install CANN#

A2 CANN is already installed in the 910B image. A3 CANN is already installed in the 910C image.
You can register an account at https://www.hiascend.com/developer/download/community/result?module=cann and download the corresponding cann-ops for your platform.

# cann-toolkit (A2|A3)
chmod +x Ascend-cann-toolkit_9.0.0_linux-aarch64.run
./Ascend-cann-toolkit_9.0.0_linux-aarch64.run --install
# cann-ops for 910B (A2)
chmod +x Ascend-cann-910b-ops_9.0.0_linux-aarch64.run
./Ascend-cann-910b-ops_9.0.0_linux-aarch64.run --install
# cann-ops for 910C (A3)
chmod +x Ascend-cann-A3-ops_9.0.0_linux-aarch64.run
./Ascend-cann-A3-ops_9.0.0_linux-aarch64.run --install

2.2 Manually download the FlagTree dependencies#

If your network connection is available, you do not need to download the dependencies which will be fetched automatically during the build.

mkdir -p ~/.flagtree/ascend; cd ~/.flagtree/ascend
wget https://baai-cp-web.ks3-cn-beijing.ksyuncs.com/trans/llvm-7d5de303-ubuntu-aarch64-python311-compat_v0.6.0.tar.gz
tar zxvf llvm-7d5de303-ubuntu-aarch64-python311-compat_v0.6.0.tar.gz

To check out which commit of flir & FlagPrism, please refer to https://github.com/flagos-ai/FlagTree/blob/triton_v3.5.x/python/setup_tools/utils/init.py

cd ${YOUR_CODE_DIR}/FlagTree/third_party
git clone https://github.com/flagos-ai/flir.git
git clone https://github.com/flagos-ai/FlagPrism.git

To check out which commit of AscendNPU-IR, please refer to https://github.com/flagos-ai/FlagTree/blob/triton_v3.5.x/python/setup_tools/utils/ascend.py

cd ${YOUR_CODE_DIR}/FlagTree/third_party/ascend
git clone https://github.com/flagos-ai/FlagTree-AscendNPU-IR.git

2.3 Manually download the Triton dependencies#

The Triton dependencies are already downloaded and installed in the image. If your network connection is available, you do not need to download the dependencies which will be fetched automatically during the build.

cd ${YOUR_CODE_DIR}/FlagTree
# For Triton 3.5 (aarch64)
wget https://baai-cp-web.ks3-cn-beijing.ksyuncs.com/trans/build-deps-triton_3.5.x-linux-aarch64.tar.gz
sh python/scripts/unpack_triton_build_deps.sh ./build-deps-triton_3.5.x-linux-aarch64.tar.gz

After executing the above script, the original ~/.triton directory will be renamed, and a new ~/.triton directory will be created to store the pre-downloaded packages. Note that the script will prompt for manual confirmation during execution.

2.4 Build Commands#

cd ${YOUR_CODE_DIR}/FlagTree
git checkout -b triton_v3.5.x origin/triton_v3.5.x
export PATH=~/.flagtree/ascend/llvm-7d5de303-ubuntu-aarch64-python311-compat/bin/:${PATH}  # clang
export FLAGTREE_BACKEND=ascend
MAX_JOBS=32 python3 -m pip install . --no-build-isolation -v

3. Testing and validation#

After installing flagtree, you can check it with:

python3 -m pip show flagtree

Before testing, you need to execute source /usr/local/Ascend/ascend-toolkit/set_env.sh

Refer to Tests of ascend3.5 backend

4. Run Qwen vLLM benchmark#

4.1 Use the image (910C)#

IMAGE=harbor.baai.ac.cn/flagtree/flagtree-ascend3.5-910c-py311-cann9.0.0-ubuntu22.04-aarch64:202608-torch2.10.0-vllm0.20.2

4.2 Install FlagOS#

Install flagtree as described above.

Install flag_gems and vllm-plugin-fl as follows.

git clone https://github.com/flagos-ai/FlagGems.git
cd FlagGems; git checkout qwen-vllm_for_ascend
python3 -m pip install --no-build-isolation .

git clone https://github.com/flagos-ai/vllm-plugin-FL.git
cd vllm-plugin-FL
python3 -m pip install --no-build-isolation .

4.3 Download the model#

python3 -m modelscope.cli.cli download --model Qwen/Qwen3.6-27B \
    --local_dir ${MODEL_DIR}/Qwen3.6-27B
python3 -m modelscope.cli.cli download --model Qwen/Qwen3.6-35B-A3B \
    --local_dir ${MODEL_DIR}/Qwen3.6-35B-A3B

4.4 Run the benchmark#

export BENCH_SCRIPT_DIR="${GIT_DIR}/FlagTree/.github/workflows/benchmark/ascend/ascend3.5-qwen3.6"
cd ${MODEL_DIR}
bash ${BENCH_SCRIPT_DIR}/start.sh
bash ${BENCH_SCRIPT_DIR}/test.sh
