tf 报错提示ValueError: setting an array element with a sequence.

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。
