Apple Silicon M1 Homebrew 安装及使用简介

由 拥有回忆 提交于 2020-12-14 10:10:05
原安装指令： /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" 改为新指令： arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" 对应的，其它使用场景也需要在指令前加上 arch -x86_64 brew install xxx arch -x86_64 brew update xxx 如果不想每次都加前辍也可以执行以下指令 alias ibrew=arch -x86_64 brew 来源： oschina 链接： https://my.oschina.net/quicker/blog/4795055

面试官 | 什么是递归算法？它有什么用？

由 有些话、适合烂在心里 提交于 2020-12-12 14:57:22
前言 递归是算法中一种非常重要的思想，应用也很广，小到阶乘,再在工作中用到的比如统计文件夹大小，大到 Google 的 PageRank 算法都能看到，也是面试官很喜欢的考点 最近看了不少递归的文章，收获不小，不过我发现大部分网上的讲递归的文章都不太全面，主要的问题在于解题后大部分都没有给出相应的时间/空间复杂度，而时间/空间复杂度是算法的重要考量!递归算法的时间复杂度普遍比较难（需要用到归纳法等），换句话说，如果能解决递归的算法复杂度，其他算法题题的时间复杂度也基本不在话下。另外，递归算法的时间复杂度不少是不能接受的，如果发现算出的时间复杂度过大，则需要转换思路，看下是否有更好的解法 ，这才是根本目的，不要为了递归而递归！ 本文试图从以下几个方面来讲解递归 什么是递归？ 递归算法通用解决思路 实战演练（从初级到高阶） 力争让大家对递归的认知能上一个新台阶，特别会对递归的精华:时间复杂度作详细剖析，会给大家总结一套很通用的求解递归时间复杂度的套路，相信你看完肯定会有收获 什么是递归 简单地说，就是如果在函数中存在着调用函数本身的情况，这种现象就叫递归。 以阶乘函数为例,如下, 在 factorial 函数中存在着 factorial(n - 1) 的调用，所以此函数是递归函数 public int factorial ( int n) { if (n < = 1 ) {

Jupyter Notebook ModuleError after Homebrew Upgrade

由 感情迁移 提交于 2020-12-12 10:25:12
问题 I have been using Jupyter for some time now and it has worked just fine. I have Jupyter and Python installed via Homebrew. I am running on MacOS. Yesterday, I ran the command brew upgrade and now my Jupyter notebook is unable to find any of the installed python packages. I will use Numpy as the example. When inside of a Jupyter notebook, I try to do import numpy I get the message: ModuleNotFoundError: No module named 'numpy' If, however, I launch python in a terminal window, then I can import

mac安装homebrew,xcode报错

由 半城伤御伤魂 提交于 2020-12-11 13:30:33
环境：mac10.15.6 安装homebrew时报错 具体错误： no developer tools were found at ‘/Applications/Xcode.app’, requesting install. Choose an option in the dialog to download the command line developer tools. 报错原因：mac没有装xcode，xcode居然有11个G 解决方法：其实不需要下xcode，只需要下一个xcode的管理工具（个人理解），而且只有不到800M（亲测有效） 下载地址：https://developer.apple.com/download/more/ 再次执行安装命令就可以了 /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)” 完成~ 来源： oschina 链接： https://my.oschina.net/u/4412439/blog/4791880
