• 4. If the issue you raised is not a bug but a question, please raise a discussion at https://github.com/sgl-project/sglang/discussions/new/choose Otherwise, it will be closed.

Describe the bug

sglang/scripts/playground/bench_speculative.py cannot be run. I followed the instructions in the comments at the beginning of the script, but it gave an error after running it.

AttributeError: 'tuple' object has no attribute 'prompt'

The reason may be as follows: when the script uses dummy data to organize input_requests, it does not organize it into a list of DatasetRow.

Reproduction

python3 bench_speculative.py --model-path deepseek-ai/DeepSeek-V3 --speculative-draft-model-path lmsys/DeepSeek-V3-NextN --tp-size 8 --trust-remote-code --batch-size 1 4 8 16 32 --steps 0 1 2 --topk 0 1 2 4 --num_draft_tokens 0 2 4 8
