TensorFlow：苗條的訓練循環崩潰「沒有會話工廠註冊」

Question

我有一個工作TF安裝和苗條工作也很好。

但是，當我嘗試運行一個苗條的訓練循環時，我的應用程序崩潰。

最少的代碼：

import tensorflow as tf 
import tensorflow.contrib.slim as slim 


# Load data. 
... 


graph = tf.Graph() 
with graph.as_default(): 

    # Build model 
    ... 

    # Add losses 
    ... 

    # Create training operation and start the actual training loop. 
    train_op = ... 

    # Start training loop 

    slim.learning.train(
     train_op, 
     logdir=FLAGS.logdir, 
     save_summaries_secs=FLAGS.save_summaries_secs, 
     save_interval_secs=FLAGS.save_interval_secs, 
     master=FLAGS.master, 
     is_chief=(FLAGS.task == 0), 
     startup_delay_steps=(FLAGS.task * 20), 
     log_every_n_steps=FLAGS.log_every_n_steps) 

當我跑，我得到：

相反，同樣的模型將訓練時train_op爲 「手動」 之稱：

有沒有人有一個想法在哪裏開始調試？

謝謝 菲利普

Answer 1

它看起來像這條線是造成問題：

master=FLAGS.master, 

從錯誤信息，似乎修身正試圖創建一個會話sess = tf.Session("local")，這是不一個有效的會話目標。嘗試在運行腳本時傳遞標誌--master=""，或在調用slim.learning.train()時明確設置master=""。
