I want to share my experience ,maybe it's helpful.
Here is how I fixed it.
I want to use gru cell and basic rnn cell ,so I adapt the programme ... | 3 | 1 | 1 | I am using MultiRNNCell from tensorflow.models.rnn.rnn_cell. This is how declare my MultiRNNCell
Code:
e_cell = rnn_cell.GRUCell(self.rnn_size)
e_cell = rnn_cell.MultiRNNCell([e_cell] * 2)
Later on I use it from inside seq2seq.embedding_rnn_decoder as follows

If your initial_vector size is [batch_size,50].
Then initial_vector = tf.concat(1,[initial_vector,initial_vector])
Now input this to decoder as initial vector. | 3 | 1 | 1 | I am using MultiRNNCell from tensorflow.models.rnn.rnn_cell. This is how declare my MultiRNNCell

Every node finds it's 5 local maximums.
You combine all the local maximums and you keep the 5 max of them,
which is the answer. | 1 | 0 | 1 | total noob question. I have a file that contains a number on each line, there are approximately 5 millions rows, each row has a different number, how do i find the top 5 values in the file using spark and python. | spark python product top 5 numbers from a file | 0.197375 | 0 | 0 | 54 |

You can't store an object directly by hash in Python code (it may be possible by calling internal C functions in CPython).

What would be the risks for exposing them and consequntly, accessing the dict by hashes not keys? | Get dictionary keys hashes without recalculation | 0.197375 | 0 | 0 | 472 |

I have seen that it is possible using the index of the object using the np.delete function, but I'm looking for a way to do it having the object but not its index.
