Description

This causes a GPU error when using cuda_graph with large input sizes. By default, SGLang’s unit tests include test_mmlu, which runs multi-task models for performance comparison. The test crashes during cuda_graph loading due to the large size.

python3 -m unittest -v test_wave_attention_backend.TestWaveAttnBackend.test_mmlu
