### step 1. build paddle lib
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
# WITH_MKL=ON|OFF
|
||
|
|
# WITH_MKLDNN=ON|OFF
|
||
|
|
|
||
|
|
PADDLE_LIB=/paddle/lib/dir
|
||
|
|
cmake .. -DCMAKE_INSTALL_PREFIX=$PADDLE_LIB \
|
||
|
|
-DCMAKE_BUILD_TYPE=Release \
|
||
|
|
-DWITH_FLUID_ONLY=ON \
|
||
|
|
-DWITH_GPU=OFF \
|
||
|
|
-DWITH_STYLE_CHECK=OFF \
|
||
|
|
-DWITH_MKL=OFF \
|
||
|
|
-DWITH_MKLDNN=OFF
|
||
|
|
make -j8
|
||
|
|
make -j8 inference_lib_dist
|
||
|
|
```
|
||
|
|
|
||
|
|
### step 2. generate program desc
|
||
|
|
```
|
||
|
|
# please install paddle before run this scripe
|
||
|
|
pip install --upgrade paddlepaddle-*.whl
|
||
|
|
python demo_network.py
|
||
|
|
```
|
||
|
|
|
||
|
|
This will generate two program desc files:
|
||
|
|
- startup_program: used to init all parameters
|
||
|
|
- main_program: main logic of the network
|
||
|
|
|
||
|
|
### step 3. build demo_trainer and run it.
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
# Make a build dir at the same dir of this README.md document.
|
||
|
|
# The demo dir can be put anywhere.
|
||
|
|
mkdir build
|
||
|
|
cd build
|
||
|
|
|
||
|
|
# WITH_MKL=ON|OFF
|
||
|
|
# WITH_MKLDNN=ON|OFF
|
||
|
|
PADDLE_LIB=/paddle/lib/dir
|
||
|
|
|
||
|
|
# PADDLE_LIB is the same with CMAKE_INSTALL_PREFIX when building the lib
|
||
|
|
cmake .. -DPADDLE_LIB=$PADDLE_LIB \
|
||
|
|
-DWITH_MKLDNN=OFF \
|
||
|
|
-DWITH_MKL=OFF
|
||
|
|
make
|
||
|
|
|
||
|
|
# copy startup_program and main_program to this dir
|
||
|
|
cp ../startup_program .
|
||
|
|
cp ../main_program .
|
||
|
|
|
||
|
|
# run demo cpp trainer
|
||
|
|
./demo_trainer
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
The output will be:
|
||
|
|
```
|
||
|
|
step: 0 loss: 1069.02
|
||
|
|
step: 1 loss: 1069.02
|
||
|
|
step: 2 loss: 1069.02
|
||
|
|
....
|
||
|
|
```
