Mobile MNN model compatibility assurance program
Compatibility issues arise at three main levels: chip architecture, operating system version and memory management, and can be prevented by the following measures:
- ABI Adaptation Program: 1) Configure ndk abiFilters 'armeabi-v7a', 'arm64-v8a' in build.gradle 2) Verify the model compatibility using the MNN provided ' checkNCNNModel' tool to verify model compatibility.
- System Version Adaptation: 1) Minimum compatible API Level should be set to 21 (Android 5.0) 2) Separate handling of storage permissions for Android 10+ devices
- RAM leak detection: 1) Explicitly release resources using 'MNN::Tensor::release' 2) Monitor native memory via Android Profiler 3) Set the HINT_COST parameter of 'Interpreter::setSessionHint HINT_COST parameter of 'Interpreter::setSessionHint'.
- Exception handling mechanism: Wrapping 'try-catch' blocks to catch 'MNN::Error' exceptions to implement an auto-degradation policy
Recommended test solution: do real machine testing on Huawei EMUI, Xiaomi MIUI and other customized systems, focusing on verifying the EGL context compatibility of the image generation module.
