i have following piece of code: $item['price'] = 0; /*code item information goes in here*/ if($item['price'] == 'e') { $item['price'] = -1; } it intended initialize item price 0 , information it. if price informed 'e' means exchange instead of sell, indicated negative value because stored in database requires numeric value. there possibility leave price 0, either because item bonus or because price set in later moment. but, when price not set, leaves initial value of 0, if loop indicated above evaluates true , price set -1. is, considers 0 equal 'e'. how can explained? edit: when price provided 0 (after initialization), behavior erratic: if evaluates true, evaluates false. you doing == sorts out types you. 0 int, in case going cast 'e' int. not parseable one, , become 0 . string '0e' become 0 , , match! use ===

i'm training lstm cell on batches of sequences have different lengths. tf.nn.rnn has convenient parameter sequence_length , after calling it, don't know how pick output rows corresponding last time step of each item in batch. my code follows: lstm_cell = tf.nn.rnn_cell.lstmcell(num_lstm_units, input_size) lstm_outputs, state = tf.nn.rnn(lstm_cell, input_list, dtype=tf.float32, sequence_length=sequence_lengths) lstm_outputs list lstm output @ each time step. however, each item in batch has different length, , create tensor containing last lstm output valid each item in batch. if use numpy indexing, this: all_outputs = tf.pack(lstm_outputs) last_outputs = all_outputs[sequence_lengths, tf.range(batch_size), :] but turns out time begin tensorflow doesn't support (i'm aware of feature request ). so, how these values? a more acceptable workaround published danijar on feature request page linked in question. doesn't need evaluate tensors, big p...
