However, whe I look for packages with anaconda search -t conda pyspharm It appears as if there are no channels with a package made for the win-64 platform. Is there any way I can still install it? 回答1: Crate a 32bit python environment: set CONDA_FORCE_32BIT=1 conda create -n py27_32bit python=2.7 enable py27_32bit conda install --channel https://conda.anaconda.org

使用vuecli3发布npm包

一.使用vuecli3创建项目 vue create svgicon 二.修改目录,开发组件前的准备 把src目录改为examples作为查看组件的演示目录,新建packages目录作为组件编写的目录。 在packages下新建index.js作为导出组件入口,作为整个组件库的导出,新建组件文件夹作为组件源码的放置,比如我的组件目录叫做 svg-icon ,在svg-icon文件夹下新建index.js文件对外提供对文件的引用,新建src文件夹并创建svg-icon.vue作为组件文件。整个packages文件夹下是如下的样子: 在项目根目录下新建vue.config.js并添加如下修改 src 目录 为 examples 目录 module.exports = { // 修改 src 目录 为 examples 目录 pages: { index: { entry: 'examples/main.js', template: 'public/index.html', filename: 'index.html' } } } 三.编写组件 <template> <dir>一个新的svg-icon组件</dir> </template> 在packages/svg-icon/index.js导出组件 // 导入组件,组件必须声明 name import SvgIcon from '.

How do I set R_LIBS_SITE on Ubuntu so that .libPaths() is set properly for all users at startup?

穿精又带淫゛_ 提交于 2019-12-06 11:38:51
问题 I am setting up a cluster where all nodes have access to /nfs/software , so a good place to install.packages() would be under /nfs/software/R . How do I set R_LIBS_SITE so that this is automatically part of all users' R environment? I tried prepending to the path given for R_LIBS_SITE in /etc/R/Renviron but help(Startup) says "do not change ‘R_HOME/etc/Renviron’ itself", which I'm not sure is the same file since R_HOME expands to /usr/lib/R , but has no effect in any case.

Package for fast determination of similarity between two bit sequences

不问归期 提交于 2019-12-06 11:20:50
I need to compare a query bit sequence with a database of up to a million bit sequences. All bit sequences are 100 bits long. I need the lookup to be as fast as possible. Are there any packages out there for fast determination of the similarity between two bit sequences? --Edit-- The bit sequences are position sensitive. I have seen a possible algorithm on Bit Twiddling Hacks but if there is a ready made package that would be better. If the database is rather static, you may want to build a tree data structure on it. Search the tree recursively or in multiple threads and per search keep an

centos7的服务器,没有yum,没有wget命令真的寸步难行,经过总结和查询,现在算搞定了,把经验总结一下,以免大家再浪费时间去找原因; 安装yum需要wget安装yum的rpm包,所以前提是先有wget,服务器上没有wget的包怎么办,就去国内的镜像源去找,我这里是找的网易163的, http://mirrors.163.com/centos/7/os/x86_64/Packages/ 需要什么从里面找到下载下来就好了, 注意了,如果你看到别人的博客,给了一个例子,你去下载,发现包不存在 ,那就去这个地址中找最新的来下载 1.下载wget的rpm包 首先去 http://mirrors.163.com/centos/7/os/x86_64/Packages/ 找到wget的rpm包,复制链接,使用curl命令下载 使用curl下载 curl http://mirrors.163.com/centos/7/os/x86_64/Packages/wget-1.14-18.el7_6.1.x86_64.rpm 下好后使用rpm命令安装wget: rpm -ivh wget-1.14-18.el7_6.1.x86_64.rpm 2.安装yum 1.删除原有的yum # rpm -aq|grep yum|xargs rpm -e --nodeps 2.下载yum

R语言包 R语言的包是R函数,编译代码和样本数据的集合。 它们存储在R语言环境中名为“library”的目录下。 默认情况下,R语言在安装期间安装一组软件包。 随后添加更多包,当它们用于某些特定目的时。 当我们启动R语言控制台时,默认情况下只有默认包可用。 已经安装的其他软件包必须显式加载以供将要使用它们的R语言程序使用。 所有可用的R语言包都列在R语言的包。 下面是用于检查,验证和使用R包的命令列表。 检查可用R语言的包 获取包含R包的库位置 .libPaths() 当我们执行上面的代码,它产生以下结果。 它可能会根据您的电脑的本地设置而有所不同。 [2] "C:/Program Files/R/R-3.2.2/library" 获取已安装的所有软件包列表 library() 当我们执行上面的代码,它产生以下结果。 它可能会根据您的电脑的本地设置而有所不同。 Packages in library ‘C:/Program Files/R/R-3.2.2/library’: base The R Base Package boot Bootstrap Functions (Originally by Angelo Canty for S) class Functions for Classification cluster "Finding Groups in Data":

Android separate packages

对着背影说爱祢 提交于 2019-12-06 07:16:54
问题 I have a large UI (about 20-25 screens). How should I organize my code? Should I separate by functionality into different packages? Should I have one package for all UI classes and then create sub packages to organize? Or should I not create separate packages and organize into folders. Any help would be greatly appreciated. 回答1: When you create a folder, it becomes a package. My favourite structure for large projects is as follows: UI Core / Logic DAO / Connections Utils Models / TOs / VOs

What access modifier for testable helper methods?

|▌冷眼眸甩不掉的悲伤 提交于 2019-12-06 06:42:15
问题 In Java, helper methods are often marked protected instead of private , so that unit tests within the same package can test the helper methods. (Specifically, I am using JUnit.) This does not seem to work in Kotlin. What access modifier is recommended instead? 回答1: internal (or no modifier) works well here 来源: https://stackoverflow.com/questions/30000983/what-access-modifier-for-testable-helper-methods

Spyder - python - install external packages

半世苍凉 提交于 2019-12-06 05:41:14
问题 I have just started to use python (within Windows, 64bit) - and I have a basic question on how to install external packages within the anaconda / spyder environment. I understand that for most packages one can simply use “conda install bunnies”. However, certain packages are not in the anaconda repository, and might have be installed externally (e.g. from github). For those packages, in order to have spyder to recognize this package – does one only in addition have to update the PYTHONPATH
