如果这是JSON响应:

"entity": "{\"Successful Requests\":[...],\"Failed Requests\":[]}",

那么实体是类型字符串。请注意开始和结束时的引号。另请注意,所有内部引号均使用后斜切逃脱。

错误消息完全说明,它不能将该字符串转换为对象。它确实期望的东西更像

"entity": {"Successful Requests":[...], "Failed Requests":[]},

If this is the JSON response:

"entity": "{\"Successful Requests\":[...],\"Failed Requests\":[]}",

then entity is of type string. Note the quotes in the beginning and the end. Also note that all the inner quotes are escaped using backslashes.

And the error message says exactly that, it cannot convert that string into an object. it did expect something more like

"entity": {"Successful Requests":[...], "Failed Requests":[]},

我认为这种替代是进入解决方案的间接方式。如果要检索所有数字,我建议 gregexpr

matches <- regmatches(years, gregexpr("[[:digit:]]+", years))
as.numeric(unlist(matches))

如果字符串中有多个匹配项,则将获得所有匹配项。如果您仅对第一场比赛感兴趣,请使用 REGEXPR 而不是 gregexpr ,您可以跳过 lintist

I think that substitution is an indirect way of getting to the solution. If you want to retrieve all the numbers, I recommend gregexpr:

matches <- regmatches(years, gregexpr("[[:digit:]]+", years))
as.numeric(unlist(matches))

If you have multiple matches in a string, this will get all of them. If you're only interested in the first match, use regexpr instead of gregexpr and you can skip the unlist.

我让它起作用。首先,我仍然不知道为什么bash命令无法正确找到 sqlc.yaml 文件。但是,在Windows 10 OS下,我成功地定位并生成文件,并使用文档

该命令是: docker run -rm -v“%cd%:/src” -w/src kjconroy/sqlc生成仅使用 cmd ,该命令还可以合并工作用makefile。

I got it working. First of all, I still have no idea why bash command cannot correctly locate the sqlc.yaml file. However, under Windows 10 OS, I succeeded locate and generating files with the command provided by docs.

The command is: docker run --rm -v "%cd%:/src" -w /src kjconroy/sqlc generate using ONLY CMD and the command also works combined with the MakeFile.

renderdoc向您展示了任何更新方法( glbuffersubdata ,通过持续的映射指示器等)更新了多少内存)诸如持续映射的指针之类的方法)。

Renderdoc shows you how much memory is updated by any of your update methods (glBufferSubData, through persistent mapped pointers, etc etc) any time such an update is done (again, very important to track for more transparent update methods like persistent mapped pointers).

OpenGL-是否有一种方法可以跟踪Glbufferdata / glbuffersubdata分配的实际使用内存?

最简单的解决方案如下:

.outer-div{
  width: 100%;
  height: 200px;
  display: flex;
  border:1px solid #000;
}
.inner-div{
  margin: auto;
  text-align: center;
  border: 1px solid red;
}
<div class="outer-div">
  <div class="inner-div">
    Hey there!
  </div>
</div>

The easiest solution is below:

.outer-div{
  width: 100%;
  height: 200px;
  display: flex;
  border:1px solid #000;
}
.inner-div{
  margin: auto;
  text-align: center;
  border: 1px solid red;
}
<div class="outer-div">
  <div class="inner-div">
    Hey there!
  </div>
</div>

这是因为您的 match()仅在寻找数字( \ d ),而不是任何字符():

function makeid(length) {
  var result = "";
  var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  for (var i = 0; i < length; i++) {
    result += characters[Math.floor(Math.random() * characters.length)];

  }
  result = result.match(/.{1,4}/g).join("-");
  return result;
}

console.log(makeid(15));

您可以通过使用操作员来摆脱慢匹配一起:

function makeid(length) {
  var result = "";
  var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  for (var i = 0; i < length; i++) {
    result += characters[Math.floor(Math.random() * characters.length)];
    if (i+1 < length && !((i+1) % 4))
      result += "-";
  }
  return result;
}

console.log(makeid(16));

It's because your match() is only looking for digits ( \d ) and not any character ( . ):

function makeid(length) {
  var result = "";
  var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  for (var i = 0; i < length; i++) {
    result += characters[Math.floor(Math.random() * characters.length)];

  }
  result = result.match(/.{1,4}/g).join("-");
  return result;
}

console.log(makeid(15));

And you can get rid of slow match all together, by using % operator:

function makeid(length) {
  var result = "";
  var characters = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  for (var i = 0; i < length; i++) {
    result += characters[Math.floor(Math.random() * characters.length)];
    if (i+1 < length && !((i+1) % 4))
      result += "-";
  }
  return result;
}

console.log(makeid(16));

value_from_lookup 。它在Synth时间时一次查找SSM参数的云端值,并在 cdk.context.json 中缓存其值。上下文方法返回虚拟变量,直到它们解析为止。这就是您的情况。 CDK试图在查找之前使用 my_arn

有几个修复程序:

  1. Quick and-Dirty:注释 _lambda.function.from_function_arn line。合成应用程序。毫无疑问。这只是迫使缓存在使用该值之前发生。
  2. 硬码将lambda arn纳入 _lambda.function.from_function_arn 。如果功能名称和版本/别名稳定,则没有真正的缺点。提示:使用方法。

使用 cdk .lazy 。但是,我相信在python中仍然被打破。无论如何,这是在打字稿中的外观:

const my_arn = cdk.Lazy.string({
  produce: () =>
    ssm.StringParameter.valueFromLookup(
      this,
      'test-value-for-my-job-executor-new-function-lambda-arn'
    ),
});

value_from_lookup is a Context Method. It looks up the SSM Parameter's cloud-side value once at synth-time and caches its value in cdk.context.json. Context methods return dummy variables until they resolve. That's what's happening in your case. CDK is trying to use my_arn before the lookup has occurred.

There are several fixes:

  1. Quick-and-dirty: Comment out the _lambda.Function.from_function_arn line. Synth the app. Uncomment out the line. This simply forces the caching to happen before the value is used.
  2. Hardcode the Lambda ARN into _lambda.Function.from_function_arn. If the Function name and version/alias are stable, no real downside to hardcoding. Tip: use the Stack.format_arn method.

There is an elegant third alternative using cdk.Lazy. However, I believe Lazy is still broken in Python. Anyway, here is how it would look in Typescript:

const my_arn = cdk.Lazy.string({
  produce: () =>
    ssm.StringParameter.valueFromLookup(
      this,
      'test-value-for-my-job-executor-new-function-lambda-arn'
    ),
});

jsii.errors.jsiierror:arns必须从“ arn:”开始并且至少有6个组件

我已经管理了此解决方案,而无需将 uuid 设置为主要密钥:

from django.contrib import admin


class BaseModelAdmin(admin.ModelAdmin):

    """ base model admin with custom behavior """

    def get_object(self, request, object_id, from_field=None):
        """ get object based on uuid insead of id """

        # get queryset, model, field:
        queryset = self.get_queryset(request)
        model = queryset.model
        field = model._meta.get_field('uuid') if from_field is None else model._meta.get_field(from_field)
        
        # try to return instance:
        try:
            object_id = field.to_python(object_id)
            return queryset.get(**{field.name: object_id})
        except:
            return None

I've managed this solution without having to set the UUID as the primary key:

from django.contrib import admin


class BaseModelAdmin(admin.ModelAdmin):

    """ base model admin with custom behavior """

    def get_object(self, request, object_id, from_field=None):
        """ get object based on uuid insead of id """

        # get queryset, model, field:
        queryset = self.get_queryset(request)
        model = queryset.model
        field = model._meta.get_field('uuid') if from_field is None else model._meta.get_field(from_field)
        
        # try to return instance:
        try:
            object_id = field.to_python(object_id)
            return queryset.get(**{field.name: object_id})
        except:
            return None

您可以使用 seaborn (或Matplotlib)轻松执行此操作。以下是代码。

  1. 我正在创建一个大小为100x2并将其称为X的随机阵列。我正在创建一个0s和1s 100x1的随机阵列,并称其为y
>> import numpy as np
>> X = np.random.randint(100, size=(100, 2))
>> Y = np.random.choice([0, 1], size=(100))
>> X
   array([[11, 47],
       [23,  2],
       [91, 14],
       [65, 32],
       [81, 78],
       ....
>> Y
   array([0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 1,
       0, 0, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 1, 0,
       1, 0, 0, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 0, 0, 1,
       0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1])

使用Seaborn Scactplot

import seaborn as sns
sns.scatterplot(x=X[:,0], y=X[:,1], hue=Y)

输出SNS STACTPLOT

You can do this easily using seaborn (or matplotlib as well). Below is the code.

  1. I am creating a random array of size 100x2 and calling it X. I am creating a random array of 0s and 1s of size 100x1 and calling it Y
>> import numpy as np
>> X = np.random.randint(100, size=(100, 2))
>> Y = np.random.choice([0, 1], size=(100))
>> X
   array([[11, 47],
       [23,  2],
       [91, 14],
       [65, 32],
       [81, 78],
       ....
>> Y
   array([0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 1, 1, 0, 0, 1, 0, 1, 0, 1,
       0, 0, 0, 1, 1, 0, 0, 1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 1, 0,
       1, 0, 0, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 0, 0, 1,
       0, 0, 1, 1, 0, 0, 1, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 1, 1, 1, 1,
       1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 1, 1])

Use Seaborn scatterplot

import seaborn as sns
sns.scatterplot(x=X[:,0], y=X[:,1], hue=Y)

Output sns scatterplot

我看不到任何问题。调试Bittorrent客户端的一种常见方法是使用Wireshark,该Wireshark具有用于Bittorrent的协议解剖器,只要从一开始就捕获TCP连接,该协议是可行的。有了这一点,您可以看到真正的电线。为了进行比较,您还可以查看两个工作的bittorrent客户端互相交谈(尽管他们很可能在香草BEP3协议之上使用一些扩展名)。

传输发送饲养物表明,它没有遇到违反协议,这会导致立即断开连接,而仍在等待某些东西。

I don't see any issue. A common way of debugging bittorrent clients is using wireshark which has a protocol dissector for bittorrent which works as long as the TCP connection has been captured from the beginning. With that you can see what actually goes over the wire. For comparison you could also look at two working bittorrent clients talking to each other (although they're likely to use some extensions on top of the vanilla BEP3 protocol).

Transmission sending keep-alives suggests that it didn't run into a protocol violation that would result in an immediate disconnect and instead is still waiting on something.

尽管行人图书馆使用下面的社交武器(基于物理)的模型,但它还在顶部使用基于“自定义”的代理逻辑(例如,启用社交距离功能),并且无法明确访问基础参数理论模型。

您必须将其视为“黑匣子”,并且只能通过更改诸如PED直径,舒适的速度,所需的社交距离等之类的事物来间接改变行为的某些方面。 PED库过程流)。所有的所有图书馆都这样工作。您还可以在顶部添加自己的自定义(基于代理)的行为;例如,让行人定期“扫描”事物并相应地改变其行为(通常是通过过程流中的条件路径)。

Although the Pedestrian library uses a social-forces (physics-based) model underneath, it also uses 'custom' agent-based logic on top (e.g., to enable the social distancing functionality) and there is no explicit access to parameters of the underlying theoretical model.

You have to treat it as a 'black box', and you can only indirectly change some aspects of the behaviour by changing things such as ped diameter, comfortable speed, desired social distance, etc. (plus of course by building in explicit behaviour into the Ped library process flow). All the AnyLogic libraries work like this. You can also add your own custom (agent-based) behaviour on top; e.g., have pedestrians periodically 'scanning' for things and changing their behaviour (typically via conditional paths in the process flow) accordingly.
