模型已编译如下：

mlc_llm convert_weight ./dist/models/Qwen2-1.5B/ --model-type qwen2 --quantization q4f16_1 -o dist/Qwen2-1.5B-q4f16_1-MLC
mlc_llm gen_config ./dist/models/Qwen2-1.5B/ --model-type qwen2 --quantization q4f16_1 --conv-template chatml --context-window-size 2048 --max-batch-size 1 -o dist/Qwen2-1.5B-q4f16_1-MLC/

我的 mlc-package-config.json 如下：

{
 "device": "android",
 "model_list": [
 {
 "model": "/home/stephen/mlc-llm/dist/Qwen2-1.5B-Instruct-q4f16_1-MLC",
 "model_id": "Qwen2-1.5B-Instruct-q4f16_1-MLC",
 "estimated_vram_bytes": 3980990464,
 "bundle_weight": true
 }
 ]
}

然后使用 mlc_llm package 构建 libtvm4j_runtime_packed.so 和 tvm4j_core.jar。接着在 Android Studio 中打开 android/MLCChat 以构建 APK。最后使用 python bundle_weight.py --apk-path app/release/app-release.apk 将 APK 安装到 Snapdragon 8 Gen 1 芯片的 meta50 上。结果显示为

,但将相同的 APK 安装到 Kirin90000S 芯片 Maleoon 910 GPU 上时，显示 OK,只是速度变慢了：
