Addressing issues from #207
Now, filtering behavior is more verbose, handling common errors and displaying numbers of omitted buckets due to token budget (in debug log level, buckets are printed):
Legacy mode was also added, which throws a nasty error message whenever token budget is set too low, but then it omits filtering and works as it did previously (ran with
VLLM_DECODE_BS_BUCKET_MIN=128 VLLM_DECODE_SEQ_BUCKET_MIN=1024 python vllm_test.py --max-num-batched-tokens=2048
):
