python - 尝试使用 aws lambda 运行 import pytube 时出错
您好我正在尝试在我的 lambda 函数中导入 pytube,但是当我尝试运行代码时出现以下错误:
响应{“errorMessage”:“无法导入模块'index'”}
功能日志无法导入模块“索引”:没有名为“pytube”的模块
这是我的代码:
我的 IDE 说 pytube 已经安装:
已满足要求:/home/ec2-user/.local/lib/python2.7/site-packages 中的 pytube
可能是什么问题呢?
wildfly-swarm - thorntail uberjar : 引用外部模块
我在一个实现上很挣扎:
我正在尝试制作一个与目标环境完全无关的通用 uberjar。
同时,我在我的 jboss-deployment.xml 中引用了一个名为 configuration 的模块。
我希望我的 uberjar 生成对 jar 外部的这个外部模块的引用,比如说 /home/user/modules/configuration
我尝试使用 thorntail 插件的 additionalModules 属性来引用此模块,但没有任何效果。
你们是怎么做到的?
- 有一个通用的 uberjar
- 将模块外部化到包含环境需求的 uberjar
问候, 纪尧姆
c - 如何使用 ibverbs 接收以太网帧?
我想编写一个简单的测试程序来使用 ibverbs API 接收以太网帧。
下面的代码编译并运行,但从不接收任何数据包。我在 Ubuntu 18 上使用 Mellanox ConnectX-3 硬件。
问题:
如果在运行此 RX 程序时,我从另一台机器 ping Inifiniband 接口,那么 ping 会收到响应。我不希望这是因为 RX 程序应该抓取 ping 请求,并且 Linux IP 堆栈不应该看到它们,因此不应该响应。应该发生什么?
我的代码有什么明显的问题吗?
我需要指导规则吗?如果我删除 ibv_create_flow() 的调用,我应该只接收接口看到的所有数据包吗?
javascript - undefined is not a function (evaluating this.function() in react native
So what I have is this: I want to keep all the 'parse' code inside a manager that I can call from another classes and files. On this example I have a function that will only check if the user is logged in and then return different drawer navigations based on that. The problem is that I keep getting the error 'undefined is not a function (evaluating ...)'. Im kinda new to javascript and couldn't find an answer to this. Here's the code.
Thanks in advance.

c# - .NET DateTime - Server-side solution for callers Time Zone
I am building a system that allows a user to specify his/her working hours. This is stored in the database as:
- DayOfWeek: Monday
- StartTime: 08:00
- EndTime: 17:00
This information is relative to the User A, so based on his time zone. Which the user selects in his/her profile e.g. (UTC+00:00) Dublin, Edinburgh, Lisbon, London
What am I trying to Achieve?
- User B currently makes a call to a .NET Web API with a Date e.g. 01 Jan 2019.
- I need the API to return User A working hours but in User B time zone.
- User B can then book that time with User A by making a second call to the API. In this case the booking is stored in UTC date format.
What I Need?
Can someone please provide a suitable solution for this as both User A and User B can have different Time Zones?

python - Case insensitive indexing in Postgres with SQLAlchemy
Consider a declarative SQLAlchemy model with an indexed String field:
The name field is case sensitive, meaning the original case should be preserved, but efficient case-insensitive queries on the index should be supported.
What's the best way to achieve this and implement in SQLAlchemy?
Queries can use lower() if needed
but it doesn't matter too much, as long as the solution is elegant and performant.
Queries using ILIKE and Postgres-level lower() are unacceptable due to performance requirements, they've been tested and do not perform fast enough on large tables for my use case.
c - 如何检测 \n 然后将其删除?
我一直在解决一个问题。我需要扫描 a\n以结束循环并将其删除以不与其他文本一起保留在变量中。到目前为止,我有这个:
这样做是,当我按下回车键时,它会将最后一个字符保留在变量末尾。
例如我输入:' Hello'
在userinput是:' Hello'
在end是' H'
当我之后按 enter 时,结束变量应该包含 \n 但H由于某种原因它包含 ' '。感谢您提供的所有帮助

macos - 如何在 TextEdit 中更改数字的字体颜色

c# - High execution time when a property of type PropertyInfo being set on model in a custom model binder
Consider the following sample:
The class TheModel has a custom ModelBinder named TheModelBinder.
In this test, TheModelBinder decides what property/field to set based on the value of query string parameter named testMode.
Using a static Stopwatch, I started measuring the time between the end of model binding and the beginning of the action. Here are the approximate results:
If testMode == PropInfo then TheModelBinder sets value to a property of type PropertyInfo named PropInfo.
(This is pretty slow, around 800-1000 ms)
If testMode == FieldPropInfo then TheModelBinder sets value to a field of type PropertyInfo named PropInfoField.
(This one takes 0ms)
If testMode == BoxedPropInfo then TheModelBinder sets value to a property of type object named BoxedPropInfo.
(This one takes 0ms too)
Now the question is: Why the first testMode (setting the PropInfo property) increases the execution time (after the model bound successfully) up to 800-1000 milliseconds?
Tested on asp.net core 2.1 and 2.2 preview2
To test this yourself, you can do dotnet new webapi and paste the content of sample to a new file. If you run the app on port 5000, you can test the execution time using these URLs:
http://localhost:5000/test?testMode=propInfohttp://localhost:5000/test?testMode=propInfoFieldhttp://localhost:5000/test?testMode=boxedPropInfo

angular - RxJs 6 - React to concatMap in filter or takeWhile condition
I use concatMap to do two API calls consecutively, but the second one should only be run if a checkbox is checked. So this is my code:
The thing is that, if the check box is not checked, even if the first observable does not return an error, the OK function is never run, only the 'finally' one, and I need it to inform the user that the resource was created. What can I do?
I tried with takeWhile instead pipe, and same result.
