# Python: FailedPreconditionError (see above for traceback): Attempting to use uninitialized value matching\_filenames\_7 #

《machine learning with tensorflow》上第5章有这样一段代码，

原来的代码是这样的，

import tensorflow as tf    
    
    filenames = tf.train.match_filenames_once("./audio_dataset/*.wav")
    count_num_files = tf.size(filenames)
    print(count_num_files)
    filename_queue = tf.train.string_input_producer(filenames) 
    reader = tf.WholeFileReader()
    filename, file_contents = reader.read(filename_queue)
    
    with tf.Session() as sess:
        sess.run(tf.global_variables_initializer()) 
     
        num_files = sess.run(count_num_files)
     
        coord = tf.train.Coordinator()
        threads = tf.train.start_queue_runners(coord=coord)
        for i in range(num_files):
            audio_file = sess.run(filename)
            print(audio_file)

运行就是不通过，

报错如下，

FailedPreconditionError (see above for traceback): Attempting to use uninitialized value matching_filenames_7
         [[Node: matching_filenames_7/read = Identity[T=DT_STRING, _device="/job:localhost/replica:0/task:0/device:CPU:0"](matching_filenames_7)]]

解决办法

init = (tf.global_variables_initializer(), tf.local_variables_initializer())
    with tf.Session() as sess:
        sess.run(init)

我这里用的python3.6.5, 估计python版本更新后，对局部变量有了严格的初始化要求。
