问题 I'm running Python 3.5.1 on Windows Server 2013 at work. I have some embarrassingly parallel tasks that seem to work on Python 2.7 with basically the same code, but I am unable to figure out how to get it to run on Python 3.5.1. I'm using Anaconda 2.4.1 The code looks like this... I've stripped it down to basically the minimum. \ ->main.py \apackage\ ->__init__.py ->amodule.py Code for main.py from tpackage import AClass def go(): x = AClass().AFunction() return x if __name__ == '__main__': x

在Spyder 中解决 TabError: inconsistent use of tabs and spaces in indentation

出现这个问题的原因往往是因为项目的作者在编写代码时使用的编辑器对Tab键的解读与我们的编辑器不同导致的。 spyder把一个Tab解读为四个空格，而原作者的使用的编辑器则不是。解决办法就是在spyder中调出缩进对齐线：打开Tools菜单栏下的Preferences 然后就可以看见代码中的空格和缩进的区别了：箭头是原作者的编辑器对Tab键的误读，我们这里在spyder中哦用Tab键或者四个空格替换掉就好了。来源： CSDN 作者： Thinker_and_FKer 链接： https://blog.csdn.net/weixin_39123145/article/details/103937766

Updating Spyder If you installed Spyder through Anaconda (recommended), WinPython, MacPorts, or your system package manager, update using those same methods. With Anaconda, just run (in Anaconda Prompt if on Windows) conda update anaconda t o update the distribution as a whole and conda update spyder to update Spyder specifically. If you installed Spyder via the advanced/cross-platform method, pip , run pip install --upgrade spyder . This command will also update all Spyder dependencies, so we recommend you use an isolated virtualenv or venv environment to avoid any potential unintended
