测试说明¶

测试（在 fbgemm_gpu/test/ 目录中）和基准测试（在 fbgemm_gpu/bench/ 目录中）为如何使用 FBGEMM_GPU 算子提供了很好的示例。

设置 FBGEMM_GPU 测试环境¶

通过构建/安装 FBGEMM_GPU 包获得可用环境后，需要安装额外的包才能正确运行测试。

# !! Run inside the Conda environment !!

# From the /fbgemm_gpu/ directory
python -m pip install -r requirements.txt

运行 FBGEMM_GPU 测试¶

在构建/安装 FBGEMM_GPU 包后运行测试

# !! Run inside the Conda environment !!

# From the /fbgemm_gpu/test/ directory
cd test

python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning split_table_batched_embeddings_test.py
python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning quantize_ops_test.py
python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning sparse_ops_test.py
python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning split_embedding_inference_converter_test.py

使用 CUDA 变体进行测试¶

对于 FBGEMM_GPU CUDA 包，GPU 将被自动检测并用于测试。要在支持 GPU 的机器上以仅 CPU 模式运行测试和基准测试，必须在环境中设置 CUDA_VISIBLE_DEVICES=-1。

# !! Run inside the Conda environment !!

# Specify the specific CUDA devices to run the tests on
# Alternatively, set to -1 for running in CPU-only mode (when on a GPU-capable machine)
export CUDA_VISIBLE_DEVICES=-1

# Enable for debugging failed kernel executions
export CUDA_LAUNCH_BLOCKING=1

# For operators involving NCCL, if the rpath is not set up correctly for
# libnccl.so.2, LD_LIBRARY_PATH will need to be updated.
export LD_LIBRARY_PATH="/path/to/nccl/lib:${LD_LIBRARY_PATH}"

python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning split_table_batched_embeddings_test.py

使用 ROCm 变体进行测试¶

对于 ROCm 机器，需要通过在环境中设置 FBGEMM_TEST_WITH_ROCM=1 来启用对 ROCm GPU 的测试。

# !! Run inside the Conda environment !!

# From the fbgemm_gpu/test/ directory
cd test

export FBGEMM_TEST_WITH_ROCM=1

# Specify the specific HIP devices to run the tests on
#
# NOTE: This is necessary if PyTorch is unable to see the devices that
# `rocm-smi --showproductname` can see
export HIP_VISIBLE_DEVICES=0,1,2,3

# Enable for debugging kernel executions
export HIP_LAUNCH_BLOCKING=1

python -m pytest -v -rsx -s -W ignore::pytest.PytestCollectionWarning split_table_batched_embeddings_test.py

运行 FBGEMM_GPU 基准测试¶

运行基准测试

# !! Run inside the Conda environment !!

# From the fbgemm_gpu/bench/ directory
cd bench

python tbe_training_benchmark.py device
