CompiledProgram¶
The api_fluid_CompiledProgram is used to transform a program for various optimizations.
# First create the Executor.
place = fluid.CUDAPlace(0) if use_cuda else fluid.CPUPlace()
exe = fluid.Executor(place)
# Run the startup program once and only once.
exe.run(fluid.default_startup_program())
# Run the main program directly without compile.
loss = exe.run(fluid.default_main_program(),
feed=feed_dict,
fetch_list=[loss.name])
build_strategy = fluid.BuildStrategy()
build_strategy.memory_optimize = True if memory_opt else False
compiled_prog = compiler.CompiledProgram(
fluid.default_main_program(),
build_strategy=build_strategy
)
loss, = exe.run(compiled_prog,
feed=feed_dict,
fetch_list=[loss.name])
Note: fluid.Porgram
and compiler.CompiledPorgram
are completely different Programs
. fluid.Porgram
is composed of a series of operators. compiler.CompiledPorgram
compiles the fluid.Porgram
and converts it into a computational graph. compiler.CompiledPorgram
cannot be saved at present.
