尝试将字符串分为作为定界字符的字符串。

唯一的问题可能是非均匀格式。因此,解决方案可以计算空格。如果结肠后有超过1个白色的空间 - >空值。

Try to split the string into an array of strings with : as the delimitier character.

The only problem could be the nonuniform formatting. So a solution could be counting the whitespaces. If there is more than 1 whitespace after a colon -> empty value.

    Console.WriteLine("In Do Thing 1");
}

public void DoThing2()

我能够找到答案的解决方案。先决条件是共享存储(例如NAS),在同一路径下的所有机器上都可以访问。在此存储中,流以.py文件的形式存储。流和使用的本地代理不需要任何特殊准备。
注册了流量

prefect register --project "PREFECT_PROJECT_NAME" --path "PATH_TO_.py"

我只是在CLI中 。
我能够从机器A部署所有流量,并从任何其他机器上执行/安排它们

I was able to find a solution to my answer. The prerequisite is shared storage (e.g. a NAS), which is accessible on all machines under the same path. In this storage, the flows are stored in the form of .py files. Flows and used local Agents do not need any special preparations.
I simply registered my flows with

prefect register --project "PREFECT_PROJECT_NAME" --path "PATH_TO_.py"

in CLI.
I was able to deploy all my flows from machine A and execute them from/schedule them on any other machine

州长:是否可以访问像NAS这样的存储,包括多台机器的县?

datesset 是一个FullCalendar选项,它允许您在FullCalendar的当前日期范围更改时指定要运行的回调函数。因此,这实际上是一个事件处理程序。因此,您不能直接称呼它。相反,每当相关内部事件发生时,FullCalendar都会运行回调。

如果您想在其他时间获取日历的当前日期范围,则可以使用其 view 属性,该属性返回视图对象,该对象又包含当前的开始和结束日期。

var view = calendar.view;
var start = view.currentStart;
var end = view.currentEnd;

文档:

datesSet is a fullCalendar option, which allows you to specify a callback function to be run whenever fullCalendar's current date range changes. So it's effectively an event handler..therefore, you can't call it directly. Instead, fullCalendar will run the callback whenever the relevant internal event happens.

If you want to get the calendar's current date range at other times, then you can use its view property, which returns a View object, which in turn contains the current start and end dates.

var view = calendar.view;
var start = view.currentStart;
var end = view.currentEnd;

我了解使用未来的飞镖中异步编程的概念。通过这样做,我们尝试在后台进行异步而不是停止应用程序。

但这并不是真正的“背景”。 DART是合作的单线螺纹(如果我们将隔离暂时排除在外)。一次只运行一个飞镖线。

因为等待这个词会导致该程序暂时停在那里,直到完成该操作,这完全违反了异步编程的概念。

不,或多或少意味着与之相反。这更像是“我们有一些不完整的东西,如果我们等待的话会阻止我们...让我们在这里放一个书签,继续前进,然后稍后再回来看看是否完成了……”

因此,与“普通代码不同, “这必须不屈服,等待“去另一个绿色线程”的机会。

调度程序可以在此线程中暂停某些操作中的执行,例如致电等待,返回未来,呼叫收益,未来等等。

I understand the concept of asynchronous programming in Dart using Future. By doing this, we try to do things asynchronously in the background and not stop the application.

But it isn't really "in the background". Dart is cooperative single threaded (if we leave Isolates out of it for a moment). Only one dart thread is running at a time.

Because the word await causes the program to be temporarily stopped there until that operation is finished, and this is completely against the concepts of asynchronous programming.

No, it more or less means the opposite of that. It's more like "we have something that is incomplete and would block us if we waited... let's put a bookmark here, go on to other things, and come back later to see if it's done..."

So unlike "ordinary code" that has to run without yielding, an await is an opportunity to "go to another green thread".

The scheduler can suspend execution in this thread on certain operations, like calling await, returning a Future, calling yield, Future.then, and so on.

在飞镖语言中,异步/等待的确切而清晰的含义是什么

如果没有可重现的例子,很难回答。通常的怀疑是响应变量中存在过度分散,导致常规的标准错误太小。替代方案包括以下标准错误:Bootstrap,Sandwich,Quasi-Poisson或拟合负二项式模型。

参见有关R的工作示例以及第7.4章, https://discdown.org/microecormentics/ 。这些使用 sandwich()函数来自软件包 sandwich ,该功能还包括Bootstrap协方差的函数 vcovbs()

Hard to answer without a reproducible example. The usual suspicion would be that there is overdispersion in the response variable, leading to conventional standard errors that are too small. Alternatives include standard errors from: bootstrap, sandwich, quasi-Poisson, or fitting a negative binomial model instead.

See Section 3 of https://doi.org/10.18637/jss.v027.i08 for a worked example in R as well as Chapter 7.4 in https://discdown.org/microeconometrics/. These use the sandwich() function from the package sandwich which also includes a function vcovBS() for bootstrap covariances.

首先。您的JSON有一些问题。我修复了它,这就是它。

  {
  "data": {
           "Gamers": [
             { 
                "id": "5397742571",
                "startTime": "Thu, 28 Jun 2022 00:04:13 GMT",
                "points": 11.647601,
                "hash": {
                   "id": "xxxxxxxxxxxx",
                   "hash": "xxxxxxxxxx",
                   "__typename": "GamerRace"
                 }
              }
            ]
        }
    }

现在为此JSON创建模型。

public class Data
{
    public List<Gamer> Gamers { get; set; }
}

public class Gamer
{
    public string id { get; set; }
    public string startTime { get; set; }
    public double points { get; set; }
    public Hash hash { get; set; }
}

public class Hash
{
    public string id { get; set; }
    public string hash { get; set; }
    public string __typename { get; set; }
}

现在是时候将您的JSON转换为C#对象了。

Data people = JsonConvert.DeserializeObject<Data>(yourJson);

希望它能帮助您的好友。

First of all. Your json have some issue. I fix it and here is it.

  {
  "data": {
           "Gamers": [
             { 
                "id": "5397742571",
                "startTime": "Thu, 28 Jun 2022 00:04:13 GMT",
                "points": 11.647601,
                "hash": {
                   "id": "xxxxxxxxxxxx",
                   "hash": "xxxxxxxxxx",
                   "__typename": "GamerRace"
                 }
              }
            ]
        }
    }

Now Create Model for this json like below.

public class Data
{
    public List<Gamer> Gamers { get; set; }
}

public class Gamer
{
    public string id { get; set; }
    public string startTime { get; set; }
    public double points { get; set; }
    public Hash hash { get; set; }
}

public class Hash
{
    public string id { get; set; }
    public string hash { get; set; }
    public string __typename { get; set; }
}

Now its time to convert your json into c# object.

Data people = JsonConvert.DeserializeObject<Data>(yourJson);

Hope it helps you buddy.

如果您要打印 i2 ,您会很快看到引起问题的原因:

array([list([[0, 1], [0, 3], [1, 2], [1, 4], [2, 5], [3, 4], [3, 6], [4, 7], [5, 4], [6, 7]]),
       list([[0, 1], [0, 3], [1, 2], [1, 4], [2, 5], [3, 4], [3, 6], [4, 7]])],
      dtype=object)

i2 不是三维数组由2个元素列表组成)。

实际上,当您创建 i2 时,使用最近的numpy,您还应该看到 expecationWarning

VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray.
  I2=np.array([[[0, 1],

它基本上识别出相同的问题。实际上,它说明了“来自破烂的嵌套序列”。破烂的是关键:您的输入外部列表包含两个不相等的列表。结果,三维嵌套列表不为“矩形”(盒形)维度,而是列表的集合。

如果您计划以Numpy的方式使用数据,那么您实际上是:Numpy是针对常规数组的(快速)操作,而不是带有破烂的数组。

If you would print I2, you'll quickly see what is causing the problem:

array([list([[0, 1], [0, 3], [1, 2], [1, 4], [2, 5], [3, 4], [3, 6], [4, 7], [5, 4], [6, 7]]),
       list([[0, 1], [0, 3], [1, 2], [1, 4], [2, 5], [3, 4], [3, 6], [4, 7]])],
      dtype=object)

I2 is not a three dimensional array, but a one dimensional array of lists (each individual list consists of a list of 2-element lists).

In fact, when you create I2, with a recent NumPy, you should also see a DeprecationWarning:

VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray.
  I2=np.array([[[0, 1],

which essentially identifies the same problem. Indeed, it states "from ragged nested sequences". Ragged is key here: your input outer list contains two lists that are not of equal length. As a result the three dimensional nested list is not of "rectangular" (box-shaped) dimensions, but it's a collection of list.

If you planned to you use your data this way with NumPy, you can't, really: NumPy is meant for (fast) operations with regular arrays, not with ragged arrays.

物体或小部件是不可变的,并不意味着其值不会改变。

您可以声明最终列表&lt; widget&gt;儿童,因为它是最终的,这是不变的,并且仍然从中添加和删除小部件。不变的是参考。

当您使用继承的Widget时,相同。如果一个值改变,则不会重建自身和下面的所有树。即使它实际上已经更改和重建,它也不一定会重建下面的所有树,只有当小部件类型或其儿童/孩子参考也更改时,才会发生。

An object or widget being immutable does not mean its values can't change.

You can declare a final List<widget> children, which is immutable since it is final, and still add and remove widgets from it. What is immutable is the reference.

When you use the InheritedWidget is the same. If a value changes it wont rebuild itself and all the tree below. Even it is actually changed and rebuilt, it does not necessarily rebuild all tree below, it'd happen only if the widget type or its child/children reference changed also.

他们很可能在此措辞中表示 API一致性;他们自己的API或开发人员可能期望在Java库的API中找到的总体一致性。

例如,属性在Java Bean(POJO)上通常以 getter setter by Conduntion(而不是语言功能)实现在 c#)。

因此,也许 GraphStream devs想要同时以类似的方式使 getAttribute setAttribute

可以通过检查Javadoc中列出的已知实施类的一个已知实现类来确认。例如,,其中 setAttribute 方法只是调用 addattribute 直接:

    /**
     * @complexity O(log(n)) with n being the number of attributes of this
     *             element.
     */
    public void setAttribute(String attribute, Object... values) {
        addAttribute(attribute, values);
    }

分解 jar或以后< /a>工件。

It is most likely that they mean api consistency with this wording; overall consistency between their own API or what developers might expect to find in general in the API of a Java library.

For example properties on Java Beans (pojo's) are usually implemented as getter and setter methods by convention (rather than language features, as can be found in C#).

So perhaps the graphstream devs wanted to have both getAttribute and setAttribute in a similar fashion.

This can be confirmed by checking one of the Known Implementing Classes as listed in the javadoc; for example org.graphstream.graph.implementations.AbstractElement, where the setAttribute method is just calling addAttribute directly:

    /**
     * @complexity O(log(n)) with n being the number of attributes of this
     *             element.
     */
    public void setAttribute(String attribute, Object... values) {
        addAttribute(attribute, values);
    }

Taken from the decompiled jar or the sources jar of the following artifact.

graphstream setAttribute()vs addattribute()
