"""
An asynchronous Executor in Python. Through exploiting the power of
multi-core processor and data queueing, AsyncExecutor makes data reading
and cosuming decoupled, each run in multiple threads in parallel.
Instead of reading data in python side, AsyncExecutor accepts a training
file list, which will be retrieved in C++, then training inputs will be
read, parsed and fed to training network within C++ code.
AsyncExecutor is in active development and the API might change in the near
future.
Example:
>>> data_feed = fluid.DataFeedDesc('data.proto')
>>> startup_program = fluid.default_startup_program()
>>> main_program = fluid.default_main_program()
>>> filelist = ["train_data/part-%d" % i for i in range(100)]
>>> thread_num = len(filelist) / 4
>>>
>>> place = fluid.CPUPlace()
>>> async_executor = fluid.AsyncExecutor(place)
>>>
>>> async_executor.run_startup_program(startup_program)
>>>
>>> epoch = 10
>>> for i in range(epoch):
>>> async_executor.run(main_program,
>>> data_feed,
>>> filelist,
>>> thread_num,
>>> [acc],
>>> debug=False)
Args:
place(fluid.CPUPlace|None): indicate the executor run on which device.
Only CPUPlace supported
Note:
For debugging complicated network in parallel-GPUs, you can test it
on the executor. They has the exactly same arguments, and expected
the same results.
Note: Only running on CPUPlace supported.

Run program by this AsyncExecutor. Training dataset will be in filelist.
Users can also inspect certain variables by naming them in parameter
:code:`fetch`, like in fluid.Executor. Unlike fluid.Executor, however,
AsyncExecutor doesn't return fetched variables, instead, it will dump
the values of each fetched variable to stdandard output.
Running the dataset will be on multiple threads, within each a thread
local scope will be created, then all OPs also created in that scope.
Parameters are updated by all the OPs simultaneously.
Args:
program(Program): the program that need to run, if not provied,

data_feed(DataFeedDesc): A DataFeedDesc object

thread_num(int): number of concurrent training threads. See

fetch(str|list): the var name or a list of var names to inspect
mode(str): run mode of this interface
debug(bool): When set to True, fetch vars will be printed to
standard output after each minibatch
Note:
the executor will run all operators in the program but not only
the operators dependent by the fetch_list.
Note:
Running AsyncExecutor will be on multiple threads, each bound to a
CPU core. To achieve best performance, it's suggested to set thread
num to be equal or slightly less than that of CPU cores.
