-
Either of the following combination shall be enough for loading model
- alexnet.param + alexnet.bin
- alexnet.param.bin + alexnet.bin
-
Never modify Net opt member after loading
-
Most loading functions return 0 if success, except loading alexnet.param.bin and alexnet.bin from file memory, which returns the bytes consumed after loading
- int Net::load_param(const unsigned char*)
- int Net::load_model(const unsigned char*)
-
It is recommended to load model from Android asset directly to avoid copying them to sdcard on Android platform
-
The custom IO reader interface can be used to implement on-the-fly model decryption and loading
