stackflow解释 http://stackoverflow.com/questions/4674473/valueerror-setting-an-array-element-with-a-sequence
原因是在把数据输入网络的时候列表的行数列数不匹配，比如 [[1,2], [2, [3, 4]]] [[1,2], [2, 3, 4]] 而tensor必须要２＊２或者３＊３的输入才行 此时报错，只会报最后一行的错误，所以要注意有可能是前几行复制出现问题
File "main.py", line 49, in <module> model.train(sess, batch, bag_train, sen_id, lpos, rpos, real_sen, namepos) File "/home/apRE/model.py", line 225, in train self.bag_seg: bag_seg File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/client/session.py", line 767, in run run_metadata_ptr) File "/usr/local/lib/python2.7/dist-packages/tensorflow/python/client/session.py", line 938, in _run np_val = np.asarray(subfeed_val, dtype=subfeed_dtype) File "/usr/local/lib/python2.7/dist-packages/numpy/core/numeric.py", line 531, in asarray return array(a, dtype, copy=False, order=order) ValueError: setting an array element with a sequence.对应的网络输入的语句是 sess.run(self.train_op, feed_dict={ self.input: batch, self.mask: mask, self.preds: preds, self.wps1: wps_left, self.wps2: wps_right, self.bag_seg: bag_seg }) 就只会报错到最后一行，但实际上是mask那行出现了上述问题，以后需要注意。
