如果您的Web应用程序正在使用Bootstrap(ASP.NET MVC Web应用程序模板中包含Bootstrap)。
Bootstrap 5按钮 -

class=“btn btn-primary”

您正在BTN BTN之间添加额外的破折号“ - ”。尝试删除第一个破折号。

If your web app is using Bootstrap (Bootstrap is included with asp.net mvc web app templates).
Bootstrap 5 buttons -
https://getbootstrap.com/docs/5.0/components/buttons/
The bootstrap documation states:

class=“btn btn-primary”

You’re adding an extra dash “-“ between btn btn. Try removing the first dash.

如果您实际使用矩阵:

import numpy as np

a = np.array([
    [1134.01, 0.],
    [0., 1134.01]
])

print(np.matrix(a) ** -1)

输出(在线尝试!):

[[0.00088183 0.        ]
 [0.         0.00088183]]

It works if you actually use a matrix:

import numpy as np

a = np.array([
    [1134.01, 0.],
    [0., 1134.01]
])

print(np.matrix(a) ** -1)

Output (Try it online!):

[[0.00088183 0.        ]
 [0.         0.00088183]]

Python 3.8将矩阵提高到-1的功率导致INF导致INF

来自 docs ,c ++ prenti其生/代码>过载只是在通知通过时检查谓词,并且等同于

  while(!stop_waiting()){
    等待(锁);
}
 

因此,我们可以在Java中简单地做同样的事情。

while (!someCondition()) {
    conditionVariable.await();
}

From the docs, the C++ condition_variable::wait overload is just checking the predicate when a notification comes through and is equivalent to

while (!stop_waiting()) {
    wait(lock);
}

So we can simply do the same thing in Java.

while (!someCondition()) {
    conditionVariable.await();
}

Java的条件:: agait()是否支持具有谓词/功能?

尽管承诺和回调在许多情况下都可以正常工作,但后方表达出类似的内容是一种痛苦:

if (!name) {
  name = async1();
}
async2(name);

您最终会通过 async1 ;检查 name 是否未定义,并相应地致电回调。

async1(name, callback) {
  if (name)
    callback(name)
  else {
    doSomething(callback)
  }
}

async1(name, async2)

虽然好的在小例子中,当您有很多类似的情况和涉及错误处理时,它会很烦人。

纤维有助于解决问题。

var Fiber = require('fibers')

function async1(container) {
  var current = Fiber.current
  var result
  doSomething(function(name) {
    result = name
    fiber.run()
  })
  Fiber.yield()
  return result
}

Fiber(function() {
  var name
  if (!name) {
    name = async1()
  }
  async2(name)
  // Make any number of async calls from here
}

您可以检查项目此处

While promises and callbacks work fine in many situations, it is a pain in the rear to express something like:

if (!name) {
  name = async1();
}
async2(name);

You'd end up going through async1; check if name is undefined or not and call the callback accordingly.

async1(name, callback) {
  if (name)
    callback(name)
  else {
    doSomething(callback)
  }
}

async1(name, async2)

While it is okay in small examples it gets annoying when you have a lot of similar cases and error handling involved.

Fibers helps in solving the issue.

var Fiber = require('fibers')

function async1(container) {
  var current = Fiber.current
  var result
  doSomething(function(name) {
    result = name
    fiber.run()
  })
  Fiber.yield()
  return result
}

Fiber(function() {
  var name
  if (!name) {
    name = async1()
  }
  async2(name)
  // Make any number of async calls from here
}

由于模式理解是子查询的一种形式,因此您可以使用完整的子查询语法来实现所需的目标。

在这里,我假设您从 c1 开始

CALL {
  WITH c1
  MATCH (c1)<-[vg1:HAS_VOTE_ON]-(childD) 
  WITH c1, vg1 
  OPTIONAL MATCH (c1)-[rc1t:CONTAINS]->(c1t:Translation {deleted: false}) 
  WHERE ($iso6391 IS NOT null AND c1t.iso6391 = $iso6391)
  RETURN {criterion: c1, relationship: vg1, translation: c1t}
}

Since pattern comprehension is a form of a subquery, you can use complete subquery syntax to achieve what you want.

Here, I am assuming you started with c1

CALL {
  WITH c1
  MATCH (c1)<-[vg1:HAS_VOTE_ON]-(childD) 
  WITH c1, vg1 
  OPTIONAL MATCH (c1)-[rc1t:CONTAINS]->(c1t:Translation {deleted: false}) 
  WHERE ($iso6391 IS NOT null AND c1t.iso6391 = $iso6391)
  RETURN {criterion: c1, relationship: vg1, translation: c1t}
}

使用 .get()方法检索小部件值。只需更改:

def on_click():
    print(f"{e1}, {e2}, {cb}, {cbu}")

到:

# create a variable to store the Checkbutton state
cb_var = StringVar()
# update 'cbu' to use that variable
cbu = Checkbutton(main_window, variable=cb_var)


def on_click():
    print(f"{e1.get()}, {e2.get()}, {cb.get()}, {cb_var.get()}")

Use the .get() method to retrieve widget values. Simply change:

def on_click():
    print(f"{e1}, {e2}, {cb}, {cbu}")

to:

# create a variable to store the Checkbutton state
cb_var = StringVar()
# update 'cbu' to use that variable
cbu = Checkbutton(main_window, variable=cb_var)


def on_click():
    print(f"{e1.get()}, {e2.get()}, {cb.get()}, {cb_var.get()}")

您可以使用`年&lt; - `()() lubridate 替换DateTime对象的年份。

library(dplyr)
library(lubridate)

nAUR %>%
  mutate(date2 = if_else(between(date, 1484304241, 1489747821),
                         `year<-`(date, 2016), date))

更新
nAUR %>%
  mutate(date2 = if_else(between(row_number(), which(date == 1484304241)[1], which(date == 1489747821)[1]),
                         `year<-`(date, 2016), date))

You could use `year<-`() from lubridate to replace the year of a datetime object.

library(dplyr)
library(lubridate)

nAUR %>%
  mutate(date2 = if_else(between(date, 1484304241, 1489747821),
                         `year<-`(date, 2016), date))

Update
nAUR %>%
  mutate(date2 = if_else(between(row_number(), which(date == 1484304241)[1], which(date == 1489747821)[1]),
                         `year<-`(date, 2016), date))

以下是我们使用JPA注释映射父母和子体实体类的示例。

 @Entity
 @Table(name = "Parent")
 @Inheritance(strategy = InheritanceType.JOINED)
 public class Parent {

  // Getter and Setter methods 
 }

@inheritance - 定义用于实体类层次结构的继承策略。它是在实体类别的实体类中指定的。

@InHeritanceType - 定义继承策略选项。

  • 单个表层次结构策略:一个表托管类层次结构的所有实例

  • 加入子类策略:每个类别和子类都存在一个表,每个表持续存在特定于给定子类的属性。然后将实体的状态存储在其相应的类表中及其所有超类

  • 表每个类策略:每个混凝土类和子类都存在一个表,每个表都持续了类及其超类的属性。然后,该实体的状态完全存储在其类的专用表中。

      @entity
     @Table(名称=“孩子”)
     公共班级的孩子扩展父母{
    
       // getter和setter方法, 
      }
     

@inheritance(stragity = sashitanceType.joined)
应添加到父实体。 取决于场景所需的继承

。 =“ nofollow noreferrer”>第10章。继承映射

5.1.6。继承策略

Following is the example where we map Parent and Child entity classes using JPA Annotations.

 @Entity
 @Table(name = "Parent")
 @Inheritance(strategy = InheritanceType.JOINED)
 public class Parent {

  // Getter and Setter methods 
 }

@Inheritance – Defines the inheritance strategy to be used for an entity class hierarchy. It is specified on the entity class that is the root of the entity class hierarchy.

@InheritanceType – Defines inheritance strategy options.

  • Single table per class hierarchy strategy: a single table hosts all the instances of a class hierarchy

  • Joined subclass strategy: one table per class and subclass is present and each table persist the properties specific to a given subclass. The state of the entity is then stored in its corresponding class table and all its superclasses

  • Table per class strategy: one table per concrete class and subclass is present and each table persist the properties of the class and its superclasses. The state of the entity is then stored entirely in the dedicated table for its class.

     @Entity
     @Table(name="Child")
     public class Child extends Parent {
    
       //Getter and Setter methods, 
      }
    

@Inheritance(strategy = InheritanceType.JOINED)
Should be added to the parent entity. (Depending on the InheritanceType required for your scenario.)

我在文档中搜索,发现它的作品类似于React中的Usestate。因此,尝试将其与回调函数一起使用,应该看起来像是

setObjects(previous => [...previous,
        {
            id:uuidv4(),
            x:objectPosition.x,
            y:objectPosition.y,
            z:objectPosition.z,
        }])

在React中阅读有关批处理

I search in documentation and found that its works like useState in React. So try to use it with callback function, it should look like this

setObjects(previous => [...previous,
        {
            id:uuidv4(),
            x:objectPosition.x,
            y:objectPosition.y,
            z:objectPosition.z,
        }])

弗里斯特创建从表1的conters ofert sql命令,然后使用铸件列创建插入语句,

insert into table2 (categories) select categories ::integer from table1

如果您有更多的comunm,然后创建

insert into table2 (categories,column1) select categories ::integer,column1 from table1

Frist create select sql command from table 1 with the casting column and then create insert statement like this

insert into table2 (categories) select categories ::integer from table1

if you have more then 1 comunm then

insert into table2 (categories,column1) select categories ::integer,column1 from table1

在PostgreSQL中,将列的数据从Table1到Table2复制,该列是Table1和Table2中不同数据类型的数据

我不太明白,您不需要循环的解决方案吗?我只和他一起去。这里是:

Dates['Date'] = pd.to_datetime(Dates['Date'], format='%d/%m/%Y')
slope_and_dates[['Date1', 'Date2', 'Date3']] = slope_and_dates[['Date1', 'Date2', 'Date3']].apply(pd.to_datetime)

Dates = Dates.set_index('Date')
slope_and_dates['Break'] = np.nan

for i in range(len(slope_and_dates)):
    aaa = Dates.loc[slope_and_dates.loc[i, 'Date1']] + slope_and_dates.loc[i, 'slope']
    ddd = []
    ddd.append(aaa.values[0])
    fff = Dates[(Dates.index > slope_and_dates.loc[i, 'Date1']) & (Dates.index <= slope_and_dates.loc[i, 'Date3'])]
    [ddd.append(ddd[len(ddd) - 1] + slope_and_dates.loc[i, 'slope']) for x in range(1, len(fff))]
    ddd = np.array(ddd, float)
    slope_and_dates.loc[i, 'Break'] = (ddd < fff.values[:, 0]).any()


print(slope_and_dates)

I don't quite understand, you don't need solutions with a loop? I only get it with him. Here it is:

Dates['Date'] = pd.to_datetime(Dates['Date'], format='%d/%m/%Y')
slope_and_dates[['Date1', 'Date2', 'Date3']] = slope_and_dates[['Date1', 'Date2', 'Date3']].apply(pd.to_datetime)

Dates = Dates.set_index('Date')
slope_and_dates['Break'] = np.nan

for i in range(len(slope_and_dates)):
    aaa = Dates.loc[slope_and_dates.loc[i, 'Date1']] + slope_and_dates.loc[i, 'slope']
    ddd = []
    ddd.append(aaa.values[0])
    fff = Dates[(Dates.index > slope_and_dates.loc[i, 'Date1']) & (Dates.index <= slope_and_dates.loc[i, 'Date3'])]
    [ddd.append(ddd[len(ddd) - 1] + slope_and_dates.loc[i, 'slope']) for x in range(1, len(fff))]
    ddd = np.array(ddd, float)
    slope_and_dates.loc[i, 'Break'] = (ddd < fff.values[:, 0]).any()


print(slope_and_dates)

dart_vlc 软件包本身提供了一个功能,可以从当前在视频播放器中付款的视频文件中获取快照。一般结构是

videoPlayer.takeSnapshot(file, width, height)

eaxmple:

videoPlayer.takeSnapshot(File('C:/snapshots/snapshot1.png'), 600, 400)

此功能调用将捕获视频播放器作为图像的当前位置,并将其保存在上述文件中。

dart_vlc package itself provides a function to take snapshots from a video file currently paying in the video player. The general structure is

videoPlayer.takeSnapshot(file, width, height)
