[Bug]NCCL error if enable the cuda graph
Checklist
- [x] 1. I have searched related issues but cannot get the expected help.
- [x] 2. The bug has not been fixed in the latest version.
- [x] 3. Please note that if the bug-related issue you submitted lacks corresponding environment info and a minimal reproducible demo, it will be challenging for us to reproduce and resolve the issue, reducing the likelihood of receiving feedback.
- [x] 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.
- [x] 5. Please use English, otherwise it will be closed.
Describe the bug
If I don't disable cuda graph, I will get the error shown in the picture when the cuda graph is being inited. If i use the official docker image, i will not get the error. The only difference of the environment with the docker is the sglang by observing the output of python3 -m sglang.check_env. I install sglang via pip and i have observed the sglang of docker image is installed from local.
Reproduction
python3 -m sglang.launch_server --model-path deepseekr1 --tp 16 --dist-init-addr 29.111.44.27:20000 --nnodes 2 --node-rank 0 --trust-remote-code --host 0.0.0.0 --port 8000
will reproduct the error above.
add the option --disable-cuda-graph will run well

Note:
pip install nvidia-nccl-cu12==2.24.3 --no-deps
I'm on the most recent version for CUDA 11.8 (nvidia-nccl-cu11 2.21.5) and get the same error when trying to run Llama-4.
