When does this happen?

IF Deploying vLLM on V100 GPUs with chunked prefill enabled triggers an assertion error: 'mma -> mma layout conversion is only supported on Ampere'.

How others solved it

THEN Disable chunked prefill by setting the command-line argument `--enable-chunked-prefill=False` when starting vLLM. This avoids the unsupported MMA layout conversion on pre-Ampere GPUs.
