TensorFlow操作「tf.train.match_filenames_once」不工作

Question

我有下面的代碼從目錄中讀取文件名：

directory = "C:/pics/*.csv" 
file_names=tf.train.match_filenames_once(directory) 
print(file_names) 
<tf.Variable 'matching_filenames_1:0' shape=<unknown> dtype=string_ref> 

with tf.Session() as sess: 
    tf.global_variables_initializer().run() 
    print(sess.run(file_names)) 

當我運行會話我收到以下錯誤： 「試圖使用未初始化值matching_filenames「

請告訴我我做錯了什麼。

TF認爲全局和局部變量之間存在微妙的區別。此代碼按預期工作

 
import tensorflow as tf 

directory = "*.*" 
file_names = tf.train.match_filenames_once(directory) 

init = (tf.global_variables_initializer(), tf.local_variables_initializer()) 

with tf.Session() as sess: 
    sess.run(init) 
    print(sess.run(file_names))
