小编Dim*_*ims的帖子

我有几个定义相同类的bean:

  @Bean
  public FieldDescriptor fullSpotField() {
     FieldDescriptor ans = new FieldDescriptor("full_spot", String.class);
     return ans;
  }

  @Bean
  public FieldDescriptor annotationIdField() {
     FieldDescriptor ans = new FieldDescriptor("annotationID", Integer.class);
     return ans;
  }

因此,当我自动给他们

   @Autowired
   public FieldDescriptor fullSpotField;

   @Autowired
   public FieldDescriptor annotationIdField;

我得到一个例外

NoUniqueBeanDefinitionException: No qualifying bean of type [...FieldDescriptor] is defined: expected single matching bean but found ...

如何在XML配置中按名称自动装配？

我在Eclipse包浏览器中看到以下信息:

是否可以更改此位置？

许多程序通过向stdout中引出然后返回到行的开始和再次发送来显示进度条.这样他们就可以实现实时进度条的显示.

不幸的是,在许多情况下,此功能在PyCharm的控制台中不起作用.

这是一个关于如何显示keras列车进度条的示例:

即每个进度条更改进入单独的行.

有可能解决这个问题吗？

Keras中有model.summary()方法.它将表打印到stdout.是否可以将其保存到文件中？

我不明白,为什么Eclipse更新如此不可靠？大概每次我使用它,我遇到一些问题!

例如,现在我在下面遇到一堆谵妄.禁用"联系所有软件站点"没有帮助.

假设我有1x1x1x1x ...数组并希望将其转换为标量？

我该怎么做？

squeeze 没有帮助.

import numpy as np

matrix = np.array([[1]])
s = np.squeeze(matrix)
print type(s)
print s

matrix = [[1]]
print type(s)
print s

s = 1
print type(s)
print s

如何使用CSS将整个表格对齐？

margin-right 没有帮助

这里:http://jsfiddle.net/dimskraft/Y2FKy/

HTML:

<table class="block logo">
    <colgroup>
        <col style="width:50%"/>
        <col style="width:50%"/>
    </colgroup>
    <tr>
        <td>something</td>
        <td>
            <table class="menu">
                <tr>
                    <td>Item 1</td>
                    <td>Item 2</td>
                </tr>
            </table>
        </td>
    </tr>
</table>

CSS:

table {
    width: 100%;
}
table.menu {
    width: auto;
    margin-right: 0px;
}

我setUpClass()在生活中第一次尝试使用方法并写道:

class TestDownload(unittest.TestCase):

    def setUpClass(cls):
        config.fs = True

得到了:

Ran 0 tests in 0.004s

FAILED (errors=1)

Failure
Traceback (most recent call last):
  File "/opt/anaconda3/lib/python3.5/unittest/suite.py", line 163, in _handleClassSetUp
    setUpClass()
TypeError: setUpClass() missing 1 required positional argument: 'cls'

它意味着什么以及如何满足它？

在为MongoDB运行Java应用程序时,我有以下异常:

这两个名字都不属于我的申请.我在本地主机上也没有MONGODB服务器.我正在使用远程主机并稍后进行设置.关于Mongo的任何陈述之前都会发生异常.

这可能是一些 …
