小编Meg*_*Ing的帖子

我是一个更新的tensorflow,我真的不知道如何解决这个问题.

代码如下:

1. 给火车喂食价值:

   sess.run(train_op, feed_dict={images: e, labels: l, keep_prob_fc2: 0.5})
   

   Run Code Online (Sandbox Code Playgroud)

2. 使用CNN中的值:

   x = tf.placeholder(tf.float32, [None, 10 * 1024])
   

   Run Code Online (Sandbox Code Playgroud)

然后有错误

InvalidArgumentError (see above for traceback): You must feed a value for placeholder tensor 'Placeholder' with dtype float
     [[Node: Placeholder = Placeholder[dtype=DT_FLOAT, shape=[], _device="/job:localhost/replica:0/task:0/gpu:0"]()]]

Run Code Online (Sandbox Code Playgroud)

我打印输入值类型print(e.dtype),结果是float32和e.shape:(10, 32, 32, 1).

我真的不知道为什么会发生这种错误.

代码格式

第一:

 define the CNN model 
       "image = tf.placeholder(tf.float32, [FLAGS.batch_size, 32,32,1])" is here

第二:

 loss funtion and train_op is here
       "label = tf.placeholder(tf.float32, [None, FLAGS.batch_size])" is here …

请我需要一些关于错误的帮助。我有一个带有以下 jar 文件的 javafx 项目

• fontawesome-fx-8.1.jar
• sqlite-jdbc-3.8.10.1.jar
• controlfx-8.40.11.jar
• sqljdbc42.jar
• jfoenix-1.0.0.jar
• POI-3.17.jar
• poi-examples-3.17.jar
• poi-excelant-3.17.jar
• poi-ooxml-3.17.jar
• poi-ooxml-schemas-3.17.jar
• poi-scratchpad-3.17.jar

我需要的是向其中导入一些excel数据。我已经导入了上面的jar文件

但不幸的是，当我尝试运行该项目时，出现错误：

Caused by: java.lang.NoSuchMethodError: org.apache.poi.ss.usermodel.Workbook.sheetIterator()Ljava/util/Iterator;
at app.controllers.ContentAreaController.nextActionReport(ContentAreaController.java:734)
... 62 more

我试过谷歌搜索，建议我更改 poi lib 文件的版本，但没有运气。谁能建议我解决方案，因为我在这个问题上花了足够的时间

我有 python 3.6。我正在尝试使用以下方法安装 ast 库：

sudo pip3 install ast

我收到了这个错误，我不知道为什么以及如何解决它。

If executing pip with sudo, you may want sudo's -H flag.

下面的代码在python2中运行良好，但是迁移到python3后就不行了。如何在python3中更改此代码？

for i, idx in enumerate(indices):
    user_id, item_id = idx 
    feature_seq = np.array(map(lambda x: user_id, item_id))  
    X[i, :len(item_id), :] = feature_seq  # ---- error here ---- 

错误：

TypeError: int() argument must be a string, a bytes-like object or a number, not 'map'

谢谢你。
