The above exception was the direct cause of the following exception:

Traceback (most recent call last): File "/home/zbp/anaconda3/lib/python3.6/threading.py", line 916, in _bootstrap_inner self.run() File "/home/zbp/anaconda3/lib/python3.6/threading.py", line 864, in run self._target(*self._args, **self._kwargs) File "/home/zbp/anaconda3/lib/python3.6/site-packages/chainer/iterators/multiprocess_iterator.py", line 336, in _run alive = self._task() File "/home/zbp/anaconda3/lib/python3.6/site-packages/chainer/iterators/multiprocess_iterator.py", line 355, in _task data_all = future.get(_response_time) File "/home/zbp/anaconda3/lib/python3.6/multiprocessing/pool.py", line 644, in get raise self._value TypeError: 'map' object is not subscriptable

Even I use x = self.pool.apply((x,))[0],it doesn't solve the problem. Thank you.

Hi, I also met the same problem, I just use "list(map(args))" instead of "map(args)" in main.py from line 233 to line 246. However, when it comes to line 124 iterator=MultiprocessIterator(DataChef.ReID10D(args,...image_size=image_size), args.minibatch, n_prefetch=2, n_processes=args.nb_processes, shared_mem=20000000,repeat=True,shuffle=True). This file can't continue. Could you tell me how to solve this problem? THX a lot. @TJJTJJTJJ
