即使重复选择 Spinner 当前选定的项目，我也希望发生该事件。例如，如果选择了 0 并再次选择了 0，我想让事件再次飞行。

我用这段代码定义了一个扩展类。您如何将其应用于现有的 Spinner？

以下是当前来源。

我想知道是否有一种方法可以在不使用 for 循环的情况下在 Django 中引用表单集的各个表单。

这是所有文档搜索结果指向的内容：

我想知道是否有办法这样做：

我找不到任何可以做到的东西，并开始认为这是不可能的。

我正在尝试创建 x,y,z 坐标来生成高程数据集。我能够使用 meshgrid- 创建 x、y、z 数组，其中 z 是一个常数值。

（这是我上一个问题的后续，我是 python 新手）

我还想创建倾斜地形，其中 z 取决于 x。

我能够创建一个具有正确 z 值的数组。但是，当尝试使用 zip 工具将三个数组 (x,y,z) 组合成坐标时，出现此错误：

下面的代码适用于小区域，作为在更大区域上创建坡度的测试。

我认为最初可能是因为我的 z 数组是 float 而不是 int，所以我对其进行了转换，但没有任何区别。

我将 z 作为常数的代码将 z 合并到 meshgrid 中，并且 coords[] 代码在该实例中运行良好。

但是，当我尝试使 z 依赖于 x 并且不将其包含在 meshgrid 进程中时，“coords=[]”部分返回了错误：TypeError: zip argument #1 must support iteration

我在 (x,y,z) 得到最终结果

我有一个data-src需要迭代的元素数组。我将通过源 url 请求每个图像的 svg 图标数据。然后img用svg.

我已经尝试过 $.get 和 $.ajax。他们以同样时髦的方式工作。

我希望每个都img应该替换为svg. 有 6 个不同的图像元素需要迭代。但它只渲染 3 种类型的图像——另外 3 种是重复的。

编辑

根据需要，我添加了重复 3 次的 svg 图标的 HTML。id="icon/general/path"除了附加到的ids（即此处）之外<g>，其他所有内容都是相同的。

How to enable caching when running openstack_inventory.py? Mine does seems to cache and takes a long time to query the inventories for ansible.

I am tried a lot but could not figure out what and how the recursive calls should go! Please Help

This is the question: Semi-Hanoi is a problem very similar to Hanoi problem. The only difference is that your input in semi-Hanoi must be an even number of disks like 2n and they are set as shown in the following figure-a. The peg A has all the even numbered disks such as 2,4,6, … and the peg B has the rest (all the odd numbered disks such as 1,3,5,...). the rules of movement in semi-Hanoi is the same as Hanoi’s rules: • only one disk can be moved at a time • a bigger disk cannot be placed on top of a smaller one The goal is to move all the disks on the peg C in order as shown in figure-b here is the image how disks initially looks like

Spring Boot apps starting up in docker container having trouble connecting to spring cloud config server that is also running in docker container

Following is my environment:

• Docker version 18.09.6, build 481bc77
• Included spotify maven docker plugin in all the projects:
  • Cloud config server
  • Discovery Server
  • client services

after doing mvn clean install on each application, have also done the mvn docker:build that resulted as following: ~$ docker images

Spinning up the config server with following command: docker run -it -p 8888:8888 config-boot-img

This came up nicely and curl commands returns the result

$ curl http://localhost:8888/actuator/info {}XXXXXXX:~$

After config server came up successfully, I have follwoing config's yaml file for discover (Eureka) Server:

I am using git config and this is checked into one of the git repos. And when i do the curl on running config server with this yaml's config file it does return the return the configurations for disocvery-server

Now when I spin up the discovery-server with its image defined with following command: $ docker run -it -p 8761:8761 discover-boot-img

I see following log errors:

Exception Stack trace:

I'm new to python and neural network

This is a part of my code:

This is the error:

我想动态加载图像并向该图像动态添加地图标签。此外，无论不同区域的坐标（假设圆坐标）来自数据库，我都需要添加这些区域以使用 javascript/jquery 中的循环动态映射标记。

我听说过 addElement/appendChild() 方法。但如何做到这一点我不知道。

任何实现此功能的代码将不胜感激。

我需要有关如何使用 addElement/appendChild() 方法将区域标签动态添加到地图标签的帮助。

提前致谢 ！

I need to get 3 types of records in order to send reminders to those ones, first I need to send reminders after 24 hours that the records were created, then after 48 hours and finally after 72 hours.

I have done this so far but it doesn't seem to work properly because, assume that a record was created at 2019-06-10 19:00:00 when the current day turns to 2019-07-10 00:01:00 it seems to consider as if 24 hours have already passed:

How can I solve this?

PD. You can ignore the rest of the query chain that doesn't involve the dates.

我试图找到对大张量（> 200 行和列）执行路径相关更新的最有效的 tensorflow 方法。

解决方案需要是可区分的（并且可能与 xla 兼容）

我目前正在使用 tf.unstack，检查 for 循环中的每个张量并使用 tf.where 过滤掉我想要的条件。这非常慢并且导致许多张量操作

只是寻找最有效（需要最少的操作）的方法来实现这一点。

谢谢。

I am trying to test the responsiveness of the application I am building in reactjs using jest and enzyme. How can I do that?

I have a sidebar which transitions left and disappears when the screen size is less than or equal to 1024px. I went through this - Figuring out how to mock the window size changing for a react component test stackoverflow question to simulate/mock a screen resize. Then I tried using DOM functions like getComputedStyle to see if the css rule for transition is applied to the side bar. But I can't find the transform rule I applied. When I selected the side bar, stored it as a global element and did getComputedStyle over it in the browser console, it worked. What am I doing wrong?

test.ts

NavDrawer is the Component I wrote inside which I used the material ui Drawer component. To that component I applied the styles.

NavDrawer.ts

When the side bar disappears, I show the menu icon on the top bar. By clicking on it the user can open or close the side bar in smaller screens. this.props.isDrawerClose says if the drawer is opened by the user or not. It is true by default.

style.less

I found something called toHaveStyleRule but I'm not able to use it(you can see it commented in the test.ts file) because it gives tslint error Property 'toHaveStyleRule' does not exist on type 'Matchers<any>'

I also tried using the web dom api to get the element and check styles as I did in the browser console but still not working. Initially the document.getElementsByClassName was returning an empty array. So I referred to this stackoverflow question and added { attachTo: document.body } option in the mount. I could retrieve the DOM element but not able to get the same results as in browser.

In browser, following is what I did and got.

I did

which gave "matrix(1, 0, 0, 1, 0, 0)"

After resizing the screen to less than 1024px, it gave "matrix(1, 0, 0, 1, -240, 0)"

I expected the same to happen in the browser but when I consoled computerStyle.transform, it gave an empty string.

If I call a POSIX function like read() that isn't part of the C++ standard library I have to worry about it being interrupted by a signal and handle an EINTR return value. If I call a C++ standard library function like fread() based on this documentation there is no mention of EINTR so it seems like the standard library hides this from the user. Is my understanding correct and does this hold for all C++ standard library functions?

Update: So what is still not clear from the responses is that is the conclusion that one can't write standard C++ that properly functions on every platform? I'm seeing people mention POSIX behavior that is not part of the standard so this is confusing.

We are using the node package "@microsoft/microsoft-graph-client" to access Graph API from node environment.

Actually the purpose is to fetch the user contacts (outlook,live,office, hotmail) into our system through API,

API "/me/contacts" by default fetches only 10 contacts per call, so in our system we are iterating the API using "skip & @odata.nextLink" until all the contacts are received.

While referencing the API document it says API request will default provide 10 contacts, so fetching 4k contacts from my account it takes 5+ minutes.

So here there are 3 questions from our side,

1. Is there any query options to fetch maximum contacts in API?
2. To reduce the delay in fetching huge contact list say 8k contacts, is there any other API available to reduce the time delay?
3. We are trying to fetch contact list from multiple O365 account with the volume of more than 3000 contacts in each account, but we are facing lot of delay in getting those contact list through Graph API. Is there any way to get the results or data sets faster from O365 account ?

This is my texture shader program

}

Everthing works as expected. my question is that if i don't send any image data the objects render black and i will have situations where a object will have no texture attached to it.

Is their any way in glsl to solve this problem or should i send a bool varible to the shader and apply if condition

I am attempting to override a keyEvent for a handsontable. The code runs but will get the error "Uncaught TypeError: this.handleSearchNext is not a function" But it is a function defined, so I'm not sure why I am getting this error.

我已按如下请求JSON调用：fetch

我所做的是找到类型为 1 的对象并将其添加到类型为 2 的对象中。现在它看起来像这样：

在renderthis 的数据中JSON将由{this.renderLibrary()}. 还有一个JSON由fetch请求调用的，如下所示：

如您所见，JSON上面是由一些对象组成的数组，这些对象看起来是type=1first的对象JSON。在renderthis 的数据中JSON将由{this.renderLibraryFirst()}. 每个对象都JSON包含一个 onclick 函数：

我想要的是，当ChangeObjectFirst运行时，单击对象被对象替换并type=1 JSON显示{this.renderLibrary()}新数据。我该如何解决这个问题？这是我的一段代码：
