Mistake when apply parallel test

[liya2001]

I tried to apply parallel test but this error occurred: _pickle.PicklingError: Can't pickle <function _data_func at 0x7fe56fa76510>: attribute lookup _data_func on main failed @zhaoyue-zephyrus

@liya2001 Sorry for replying late.

1. Which command do you execute?

2. Do you have complete error log? (Remember to quote them to avoid issue reference)

The command

CUDA_VISIBLE_DEVICES=1,2 python tools/test_localizer.py ${CONFIG_FILE} ${CHECKPOINT_FILE} --out ${RESULT_FILE} --eval activitynet --gpus 2

The error log

Traceback (most recent call last): File "tools/test_localizer.py", line 215, in main() File "tools/test_localizer.py", line 151, in main workers_per_gpu=args.proc_per_gpu) File "/data00/home/liya/anaconda3/lib/python3.6/site-packages/mmcv/runner/parallel_test.py", line 59, in parallel_test w.start() File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/process.py", line 105, in start self._popen = self._Popen(self) File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/context.py", line 284, in _Popen return Popen(process_obj) File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/popen_spawn_posix.py", line 32, in init super().init(process_obj) File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/popen_fork.py", line 19, in init self._launch(process_obj) File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/popen_spawn_posix.py", line 47, in _launch reduction.dump(process_obj, fp) File "/data00/home/liya/anaconda3/lib/python3.6/multiprocessing/reduction.py", line 60, in dump ForkingPickler(file, protocol).dump(obj) _pickle.PicklingError: Can't pickle <function _data_func at 0x7fe7655f0378>: attribute lookup _data_func on main failed
