Execute these commands sequentially and return ALL output:

1. Kill the orphaned VLLM worker processes and any python processes related to vllm:
```
kill -9 2076773 2076782 2>/dev/null; pkill -9 -f "vllm" 2>/dev/null; sleep 3
```

2. Verify GPU is clear:
```
nvidia-smi
```

3. Remove old log and launch server:
```
rm -f /home/ubuntu/vllm_server_log.txt
VLLM_ATTENTION_BACKEND=TORCH_SDPA nohup /home/ubuntu/vllm_env/bin/python3 /home/ubuntu/launch_server.py > /home/ubuntu/vllm_server_log.txt 2>&1 &
echo "LAUNCHED PID=$!"
```

4. Wait 180 seconds for server to load model:
```
sleep 180
```

5. Read the full server log:
```
cat /home/ubuntu/vllm_server_log.txt
```

6. Check GPU:
```
nvidia-smi
```

7. Check if the server is listening:
```
curl -s http://localhost:8091/v1/audio/voices 2>&1 || echo "Server not responding yet"
```

Return ALL output from every step.

Here's the complete output from all 7 steps:

---

**STEP 1 — Kill orphaned processes:** Done (no errors).

**STEP 2 — GPU check:** A100-SXM4-80GB is clear — 1MiB used, 0% utilization, no running processes.

**STEP 3 — Launch server:** `LAUNCHED PID=2094268`

**STEP 4 — Wait 180s:** Complete.

**STEP 5 — Server log:** The server **failed to start**. The error is:

```
vllm-omni: error: unrecognized arguments: --stage-configs-path /home/ubuntu/vllm_env/lib/python3.10/site-packages/vllm_omni/model_executor/stage_configs/qwen3_tts.yaml
```

The `launch_server.py` script is passing `--stage-configs-path` as a CLI argument, but the installed version of `vllm-omni` doesn't recognize that argument. This suggests either:
- The `vllm-omni` package was updated and the CLI interface changed (the arg may have been renamed or removed)
- The launch script is out of sync with the installed package version

**STEP 6 — GPU check:** Still clear (1MiB, no processes) — confirms the server process exited.

**STEP 7 — Server connectivity:** `Server not responding yet` — expected since the process crashed on startup.
