FLAGS_check_nan_inf
(since 0.13.0)
This Flag is used for debugging. It is used to check whether the result of the Operator has Nan or Inf.
Values accepted
Bool. The default value is False.
Example
FLAGS_check_nan_inf=True will check the result of Operator whether the result has Nan or Inf.
FLAGS_cpu_deterministic
(since 0.15.0)
This Flag is used for debugging. It indicates whether to make the result of computation deterministic in CPU side. In some case, the result of the different order of summing maybe different，for example, the result of a+b+c+d may be different with the result of c+a+b+d.
Values accepted
Bool. The default value is False.
Example
FLAGS_cpu_deterministic=True will make the result of computation deterministic in CPU side.
FLAGS_enable_rpc_profiler
(Since 1.0.0)
Enable RPC profiler or not.
Values accepted
Bool. The default value is False.
Example
FLAGS_enable_rpc_profiler=True will enable rpc profiler and record the timeline to profiler file.
FLAGS_multiple_of_cupti_buffer_size
(since 1.4.0)
This Flag is used for profiling. It indicates the multiple of the CUPTI device buffer size. When you are profiling, if the program breaks down or bugs rise when loading timeline file in chrome://traxing, try increasing this value.
Values accepted
Int32. The default value is 1.
Example
FLAGS_multiple_of_cupti_buffer_size=1 set the multiple of the CUPTI device buffer size to 1.
FLAGS_reader_queue_speed_test_mode
(since 1.1.0)
Set the pyreader data queue to test mode. In test mode, pyreader will cache some data, executor will then read the cached data, so reader will not be the bottleneck.
Values accepted
Bool. The default value is False.
Example
FLAGS_reader_queue_speed_test_mode=True will enable the pyreader test mode.
