我不確定有什麼問題。我檢查了這個link並試圖解決這個錯誤,但它仍然存在。我正在嘗試讀取csv數據,然後預測列的結果。沒有額外的庫,只需準備tensorflow來獲得更好的理解。有任何想法嗎?我想用我自己的csv數據使用TensorFlow,但看到一個無害的「Enqueue操作取消」警告
編輯:
代碼:
import tensorflow as tf
filename_queue = tf.train.string_input_producer(["keystrokes-strsep.csv"])
reader = tf.TextLineReader()
key, value = reader.read(filename_queue)
# Default values, in case of empty columns. Also specifies the type of the
# decoded result.
record_defaults = [[''], [''], [''], [''], ['']]
col1, col2, col3, col4, col5 = tf.decode_csv(value, record_defaults=record_defaults)
# print tf.shape(col1)
init = tf.initialize_all_variables()
features = tf.pack([col1, col2, col3, col4])
with tf.Session() as sess:
sess.run(init)
# Start populating the filename queue.
coord = tf.train.Coordinator()
threads = tf.train.start_queue_runners(coord=coord)
for i in range(114729):
# Retrieve a single instance:
example, label = sess.run([features, col5])
coord.request_stop()
coord.join(threads)
錯誤:

哦,好吧謝謝!我想我會嘗試使用numpy代替然後,因爲這種方法不能讀取很多csv條目 – Sticky
實際上這種方法比numpy更具可擴展性,因爲它可以使用多個線程來讀取數據 –
由Google完成=確實更具可擴展性:P除了我需要它的工作xD 你建議我爲解決隊列容量問題做什麼?我剛剛開始瞭解TensorFlow及其庫文件 – Sticky
