后MATLAB时代的七种开源替代，一种堪称完美！

由 此生再无相见时 提交于 2020-12-25 18:53:14
近日，有哈工大学生表示收到了正版软件取消激活的通知，而在与 MATLAB 开发公司 MathWorks 交涉之后，被告知由于美国政府实体名单的原因，相关授权已被中止。 目前，哈尔滨工业大学、哈尔滨工程大学的老师和学生们都无法使用 MATLAB。 MATLAB大学读理工科专业的同学基本上都接触过这款软件。有分析人士指出，如果整个学校被禁用了正版 MATLAB，这意味着学校的人员再发表论文或者从事商业项目，其成果原则上就不应包含任何基于 MATLAB 的内容，这对国内相关企业和研究学者带来的影响不可忽视。 这件事在国内社交媒体迅速发酵并登上热搜，引发学术界和技术界的广泛讨论。 现在只是禁止了实体名单的上的几所高校，但是谁又能保证后续不会加码制裁打击中国高校，抑制中国科技发展呢？因此通过此次禁用事件，我们有理由说现在已经到了后MATLAB时代！急需找到MATLAB合适的替代品。 为此我们收集整理到的一些开源软件，可以起到一定的替代效果。包括：SCILAB、Octave、Spyder、Python、GMAT、GNU Radio、ROS。特别是SCILAB，他与MATLAB最为接近，近乎可以实现完美替代！ 希望本文对大家有所帮助。另外，也欢迎大家在留言区推荐你知道的替代工具。 1. “近乎完美”替代之SCILAB SCILAB 是一款与 MATLAB 类似的开源软件，可以实现 MATLAB

Win8.1 Anaconda下安装第三方库,以jieba wordcloud为例

由 拜拜、爱过 提交于 2020-12-19 07:35:04
最近在看情感分析的东西，于是在spyder里import jieba，and then就报错了。 百度之后，发现jieba是一个第三方库，它并不存在于anaconda内置的packages中。所以在用conda install jieba或者打开 Anaconda Navigator来导入都会失败。 于是，我百度，失败，再百度，再失败，再再百度，再再失败……我看的是情感分析，然后在这里卡了也就几小时…… 上演500个回合后，我终于领悟到安装的精髓了。 安装成功，终于可以导入啦！老天啊，我终于安装到了 （于是，我决定下这篇笔记，纪念这充满意义的过程） 这是我在win8.1环境下的操作，其他系统请掉头。 一.jieba 1.At first, 我们需要把jieba 下载到自己的电脑。（下载地址： https://pypi.org/project/jieba/） 页面如下：（进入后点击左侧的download files，然后点击右侧的压缩包下载） 2.下载后，解压，接着把它放到anaconda的其他库的存放位置。（jieba里有个setup.py，我们安装就是要用到这个宝宝，关键人物呀！） 我自己是把Anaconda放在F盘，然后其他库的安装包放在在F:\Anaconda\pkgs里，所以我就把下载的jieba放到这个文件夹下啦！ 3.接下来，打开电脑里的程序：Anaconda

问题 I can launch Spyder, then do absolutely nothing with it and after a while the window just disappears. I've run it from the command prompt with debug-verbose and get this just before it crashes - 2020-11-24 19:03:01,283 [DEBUG] [spyder.plugins.editor.utils.autosave] -> Autosave triggered 2020-11-24 19:04:01,292 [DEBUG] [spyder.plugins.editor.utils.autosave] -> Autosave triggered 2020-11-24 19:05:01,277 [DEBUG] [spyder.plugins.editor.utils.autosave] -> Autosave triggered 2020-11-24 19:06:01,282

由 馋奶兔 提交于 2020-12-13 03:20:20
问题 How can I install spyder 2 in Ubuntu 18.04? When I type this in the terminal: sudo apt-get install spyder it installs spyder 3. 回答1: Assuming you want spyder2 for Python 2.7: You need to install spyder for the Python version you want: python -m pip install spyder Then you just need to run it for that version. So: python -m spyder 回答2: You can use pip to install it like follows sudo pip install -Iv spyder==2.3.9 -I : reinstall (Ignore installed). v : verbose. https://pypi.org/project/spyder/

Windows Error using XGBoost with python

由 大兔子大兔子 提交于 2020-12-12 05:12:18
问题 So I'm tackling this machine-learning problem (from a previous Kaggle competition for practice: https://www.kaggle.com/c/nyc-taxi-trip-duration) and I'm trying to use XGBoost but getting an error which I have no clue how to tackle. I searched on google and stack overflow but couldn't find anyone with a similar problem. I'm using python 2.7 with the Spyder IDE through Anaconda and I'm on Windows 10. I did have some trouble installing the xgboost package so I won't completely erase the idea

“RuntimeError: This event loop is already running”; debugging aiohttp, asyncio and IDE “spyder3” in python 3.6.5

问题 I'm struggling to understand why I am getting the "RuntimeError: This event loop is already running" runtime error. I have tried to run snippets of code from "https://aiohttp.readthedocs.io/en/stable/" however, I keep getting the same issue. Code snippet from Tutorial: import aiohttp import asyncio import async_timeout async def fetch(session, url): async with async_timeout.timeout(10): async with session.get(url) as response: return await response.text() async def main(): async with aiohttp

Changing variable name in Spyder

由 时光总嘲笑我的痴心妄想 提交于 2020-11-26 10:27:12
问题 I have a program with many formulas and variables. I need to change the name of some of these variables. Is there any command or function in Spyder that can help me change all the names in one step? I am looking for something like the Matlab's MAIUSC+ENTER. 回答1: 1) Select the variable you want to change, then Press CTRL + R 2) Enter the new variable name you want. (in replace by) 3) Replace all 回答2: No way to do it currently. It's an open issue. https://github.com/spyder-ide/spyder/issues/415
