### Launch PersonaPlex Server

Source: https://github.com/nvidia/personaplex/blob/main/README.md

Starts the interactive server with SSL support. Includes an optional flag for CPU offloading when GPU memory is limited.

```bash
# Standard launch
SSL_DIR=$(mktemp -d); python -m moshi.server --ssl "$SSL_DIR"

# Launch with CPU offload
SSL_DIR=$(mktemp -d); python -m moshi.server --ssl "$SSL_DIR" --cpu-offload
```

--------------------------------

### Install Python Dependencies

Source: https://github.com/nvidia/personaplex/blob/main/README.md

Installs the PersonaPlex package and optional CUDA-enabled PyTorch dependencies for Blackwell GPUs.

```bash
pip install moshi/.
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu130
```

### Perform Offline Evaluation

Source: https://github.com/nvidia/personaplex/blob/main/README.md

Runs the model in offline mode to process input audio files into output audio and text transcripts. Supports both assistant and service-oriented role prompts.

```bash
# Assistant example
HF_TOKEN=<TOKEN> \
python -m moshi.offline \
  --voice-prompt "NATF2.pt" \
  --input-wav "assets/test/input_assistant.wav" \
  --seed 42424242 \
  --output-wav "output.wav" \
  --output-text "output.json"

# Service example
HF_TOKEN=<TOKEN> \
python -m moshi.offline \
  --voice-prompt "NATM1.pt" \
  --text-prompt "$(cat assets/test/prompt_service.txt)" \
  --input-wav "assets/test/input_service.wav" \
  --seed 42424242 \
  --output-wav "output.wav" \
  --output-text "output.json"
```
