**Question**: What should I do if model loading takes too long and NCCL timeout occurs? 1. **Question**: What should I do if model loading takes too long and NCCL timeout occurs?
Answer: You can try to add `--dist-timeout 3600` when launching the model, this allows for 1-hour timeout.i **Answer**: You can try to add `--dist-timeout 3600` when launching the model, this allows for 1-hour timeout.
2. **Question**: How to use quantized DeepSeek models?
**Answer**: DeepSeek's MLA does not have support for quantization. You need to add the `--disable-mla` flag to run the quantized model successfully. Meanwhile, AWQ does not support BF16, so add the `--dtype half` flag if AWQ is used for quantization. One example is as follows:
```bash
python3 -m sglang.launch_server --model cognitivecomputations/DeepSeek-R1-AWQ --tp 8 --trust-remote-code --dtype half --disable-mla
```
