Compile

CPP

To compile the CPP project using Android NDK, follow these steps:

1. Get the llmsdk library and header files: Clone the amlnn-toolkit repository to get the necessary libraries for compilation.

   # Clone to the parent directory of amlnn-model-playground
   git clone https://github.com/Amlogic-NN/amlnn-toolkit.git
   

2. Set the NDK path:

   export NDK_PATH=/your/ndk/path/android-ndk-r25c
   

3. Add NDK to your PATH:

   export PATH=$NDK_PATH:$PATH
   

4. Compile: Navigate to the cpp directory and run build-android.sh:

   cd examples/LLMs/cpp
   ./build-android.sh
   

5. Run: Push the compiled executable, model, and tokenizer to your Android device.

   Optional configuration:

   • Push llmsdk.so: If not already present on the device, push it to /data/local/tmp.
   • Set permissions:

     chmod +x demo_llm_main
     

   • Set environment variable:

     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/vendor/lib64/:/data/local/tmp
     

   Then execute:

   ./demo_llm_main Qwen2.5-1.5B-Instruct-F16_quant_i8_t7c.adla tokenizer.json
   

Python

System Requirements:

• OS: Ubuntu 22.04
• Python: 3.10

Verify NPU Driver Version: Execute the following commands in the serial console to check the NPU driver version:

dmesg | grep adla
strings /usr/lib/libadla.so | grep LIBADLA

The driver version must be 1.7.x or higher.

1. Install Dependencies: Ensure theamlllmPython package is installed:

   pip install amlllm-1.0.0-cp310-cp310-linux_aarch64.whl
   

2. Run: Navigate to thepydirectory and runsimple_chat.py:

   cd examples/LLMs/py
   python simple_chat.py --model <model_path> --tokenizer <tokenizer_path> [options]
   

3. Parameters:

   • --model: (Required) Path to LLM model file
   • --tokenizer: (Required) Path to tokenizer resources
   • --sampling-mode: Sampling mode, options: argmax, top_p, top_k, default: argmax
   • --top-k: Top-K parameter, default: 3
   • --top-p: Top-P parameter, default: 0.9
   • --temperature: Softmax temperature parameter, default: 1.0
   • --repeat-penalty: Repeat penalty factor, default: 1.1
   • --loglevel: Log level, options: DEBUG, INFO, WARNING, ERROR, default: ERROR
   • --model-type: Model type template, options: none, qwen, deepseek, gemma, gemma3, llama, tiny_llama, tiny_llama_v0_4, phi_1_5, phi_2, default: none

4. Usage Examples:

   # Using Qwen model
   python simple_chat.py --model Qwen2.5-1.5B-Instruct-F16_quant_i8_t7c.adla --tokenizer tokenizer.json --model-type qwen
   
   # Using Top-P sampling mode
   python simple_chat.py --model model.adla --tokenizer tokenizer.json --sampling-mode top_p --top-p 0.9 --temperature 0.8
   
   # Using Top-K sampling mode
   python simple_chat.py --model model.adla --tokenizer tokenizer.json --sampling-mode top_k --top-k 5
   

5. Interactive Commands: After the program starts, you enter an interactive interface that supports the following commands:

   • Direct input: Enter text and press Enter, the model will generate a response (streaming output)
   • exit: Exit the program
   • new_talk: Clear conversation history and start a new conversation
   • break: Interrupt the currently generating response
   • Ctrl+C: Send interrupt signal
