virtual memory exhausted: Cannot allocate memory

由 半腔热情 提交于 2019-12-30 17:36:47
问题 My compilation fails on ubuntu 12.10 with 300mb memory available (750mb total, 350mb to MySQL), 1.5ghz, I am trying to rework wt's basic hello world file into a simple ajax page. I'm pretty sure it's not a memory issue at heart since I was able to compile the original hello.C file with g++ -O3 -o hello hello.C -lwtfcgi -lwt -lboost_signals . I'm sure I'm screwing up the c++ since I ripped out the guts of HelloApplication::HelloApplication(const WEnvironment& env) : WApplication(env) and put

Embedding Ventus in WT

由 本小妞迷上赌 提交于 2019-12-24 22:02:15
问题 Hello fellow programmers! My goal is to embed a Ventus window manager (http://www.rlamana.es/ventus/), repo here (https://github.com/rlamana/Ventus) in a WT page (http://www.webtoolkit.eu/wt) and get the "Simple Example" running. I have the ventus window embedded in the WT page, however I am having a styling problem with the window. My guess this is a conflict with CSS of Ventus and WT. Which brings me here, as CSS is not my strong point. I am using visual studio2010 for my development, and I

How to clean up memory in WT?

由 穿精又带淫゛_ 提交于 2019-12-23 17:13:40
问题 UPDATE 3/27/2013 It would appear that I am not leaking memory, it is just WT not keeping a persistent session every time F5 is hit, or a new user connects. Basically the old session gets deleted, and a new one is made every time F5 is hit, or a new user connects from another machine. I have read some parts of the documentation that mention making the session persistent, so when a user reloads the page, or a different user connects they all see the same content. However, I have not been able

SVPWM学习笔记1

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> SPWM和SVPWM比较，有很多优点，我把学习SVPWM过程记录下来。 在网上查找SVPWM发现很多文章雷同，有的地方讲的不够详细，根据自己的理解补充作为笔记。 三相正弦交流电表达式如下： Ua = Um*cos(wt) Ub = Um*cos(wt-2π/3) Uc = Um*cos(wt+2π/3) Ua Ub Uc三相电压相位角相差120度，每一时刻，他们的代数和为0. Ua+Ub+Uc = 0 引入空间矢量。我们把三相电压引入到空间矢量中。为什么要引到空间矢量上，这个地方很迷惑，很多文档说为了形成旋转的磁链。 三相电机每个绕组在空间上相隔120度 三相变压器，三个绕组分别绕在三个磁芯上。 从上面电机和变压器上看到，三相绕组在空间上都有一定的角度。如果没有角度，我们那变压器来说 我们把三相绕组都绕到一个磁芯上，磁芯上产生的磁通和电流的变化率有关，如A相电流为Ia，B相电流 为Ib，C相电流为Ic，则每时每刻 Ia+Ib+Ic = 0.则产生磁通大小相互抵消，无法传递能量。对于电机都绕到一相 中合成磁通为0，更是无法旋转。 所以根据三相电机空间分布，引入空间矢量 Ua， Ub， Uc在空间上相隔120度，每个矢量的模长按照正弦变换，则 Ua模长随时间变化 ：Um*cos(wt) 记做Fa Ub模长随时间变化

Word2Vec详解

原文地址：https://www.cnblogs.com/guoyaohua/p/9240336.html 2013年，Google开源了一款用于词向量计算的工具——word2vec，引起了工业界和学术界的关注。首先，word2vec可以在百万数量级的词典和上亿的数据集上进行高效地训练；其次，该工具得到的训练结果——词向量（word embedding），可以很好地度量词与词之间的相似性。随着深度学习（Deep Learning）在自然语言处理中应用的普及，很多人误以为word2vec是一种深度学习算法。其实word2vec算法的背后是一个浅层神经网络。另外需要强调的一点是，word2vec是一个计算word vector的开源工具。当我们在说word2vec算法或模型的时候，其实指的是其背后用于计算word vector的CBoW模型和Skip-gram模型。很多人以为word2vec指的是一个算法或模型，这也是一种谬误。接下来，本文将从统计语言模型出发，尽可能详细地介绍word2vec工具背后的算法模型的来龙去脉。 Statistical Language Model 在深入word2vec算法的细节之前，我们首先回顾一下自然语言处理中的一个基本问题： 如何计算一段文本序列在某种语言下出现的概率？之所为称其为一个基本问题，是因为它在很多NLP任务中都扮演着重要的角色。 例如

How to Install Wt into a Custom Folder Without “fatal error: Wt/WApplication: No such file or directory”

问题 I'm new to Wt and c++ and I just installed the Wt webframework on Ubuntu 16.04 LTS into a custom folder in my home directory. I cannot install or build any software into the /usr diretories of this computer. Even if I could, the PPA hasn't been active for 2 1/2 years, and the official Ubuntu installation instructions are also outdated. Aptitude no longer ships with Ubuntu and will eventually be discontinued. I compliled and installed everything successfully, yet when I try to compile the

Web Application Frameworks: C++ vs Python

由 可紊 提交于 2019-12-09 15:52:09
问题 I am familiar with both Python and C++ as a programmer. I was thinking of writing my own simple web application and I wanted to know which language would be more appropriate for server-side web development. Some things I'm looking for: It has to be intuitive. I recognize that Wt exists and it follows the model of Qt. The one thing I hate about Qt is that they encourage strange syntax through obfuscated means (e.g. the "public slots:" idiom). If I'm going to write C++, I need it to be standard
