由 六月ゝ 毕业季﹏ 提交于 2020-01-02 02:46:09
问题 I'm fairly new to programming and such. I'm trying to use Spyder3, and I keep getting this error (below). I am using Geforce 1080ti, Ubuntu 18.04.01, python3.3.6, python2 is not installed. I tried $ pip3 install keyring, which is now installed but still receiving error. $ spyder3 Error initializing plugin EntryPoint('Windows (alt)', 'keyrings.alt.Windows', None, Distribution('keyrings.alt', '3.0')).

How to update Spyder?

问题 Everytime I start Spyder (with Anaconda) I get a massage saying that my version is outdated and I should update it, so I followed the instructions Spyder's own website gave me, which is running the following commands: conda update qt pyqt conda update spyder But Spyder tells me that syntax is invalid. What should I do? 回答1: ( Spyder maintainer here ) Those commands are not meant to be run inside Spyder consoles, but in a system terminal ( cmd.exe on Windows, xterm on Linux or Terminal.app on

Spyder 快捷键

Spyder 快捷键 　　Spyder是一个python的集成开发环境，其优点是模仿Matlab环境，可以方便的查看和修改数组取值。之前用过另一个开发环境PTVS(Python Tools for Visual Studio)，顾名思义，是微软的Visual Studio的python开发环境，类似经典的vc，可以方便的设置断点进行debug，当然也可以用Visual Assist X助手的功能。接触Spyder也是偶然，至于这俩孰优孰劣，现在也不好说，先边用边体会吧。 　　1.常用快捷键： 　　Ctrl + 1: 注释/反注释 　　Ctrl + 4/5: 块注释/块反注释 　　Ctrl + L: 跳转到行号 　　Tab/Shift + Tab: 代码缩进/反缩进 　　Ctrl ＋I：显示帮助 　　2. 可以在Ipython Console输入变量进行快速验证，类似matlab 　　Spyder是一个python的集成开发环境，其优点是模仿Matlab环境，可以方便的查看和修改数组取值。之前用过另一个开发环境PTVS(Python Tools for Visual Studio)，顾名思义，是微软的Visual Studio的python开发环境，类似经典的vc，可以方便的设置断点进行debug，当然也可以用Visual Assist X助手的功能。接触Spyder也是偶然

1、 Spyder是anaconda中一个python的集成开发环境，其优点是模仿Matlab环境，可以方便的查看和修改数组取值。不得不说anaconda是一个好东西，学python的可以用用，里面集成了好多开发环境，省去了我们安装软件等各种问题。只需你安心的学习相关技术即可。这一章节主要是对anaconda中的Spyder所常用的快捷键做一总汇： 　　F5:运行 　　F11:全屏 　　Ctrl + 1: 注释/反注释 　　Ctrl + 4/5: 块注释/块反注释 　　Ctrl + L: 跳转到行号 　　Tab/Shift + Tab: 代码缩进/反缩进 　　Ctrl ＋I：显示帮助 　　Tab：空行前是代码缩进；在输入一个字母后，按Tab健会自动补全或者代码提示。 　　Shift+Tab：撤销代码缩进 　　2. 可以在Ipython Console输入变量进行快速验证，类似matlab 　　3.快捷键查看方法：Tools-->Preferences-->Keyboard Shortcut 可以查看所有快捷键 　　 　　4.spyder如何调节注释颜色：——》在tools菜单里面Preferences菜单里 　　4.参考资料： 　　https://blog.csdn.net/kaever/article/details/61417682 　　https://www.cnblogs

Why does import pdb; pdb.set_trace trigger two different debugging scenarios when called differently in Spyder?

由 蓝咒 提交于 2019-12-31 07:01:11
问题 This is a follow-up question to Stepwise debugging of selected Python code. Why does import pdb; pdb.set_trace trigger two different debugging scenarios when called differently in Spyder? Here's the edited sample code in the answer from Carlos Cordoba to the question mentioned above. The code: def foo(): names = ['A', 'B', 'C'] values = [11,12,13] i = 0 import pdb; pdb.set_trace() for n in names: variable = str(n) + ' = ' + str(values[i]) print(variable) i += 1 foo() Scenario1 - Run file (F5)

background_task.py not showing messages - Python

问题 I noticed that when I ran a code snippet from the discord.py Github page it didn't show the intended message. My slightly modified code: import discord import asyncio import nest_asyncio nest_asyncio.apply() class MyClient(discord.Client): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) # create the background task and run it in the background self.bg_task = self.loop.create_task(self.my_background_task()) async def on_ready(self): print('Logged in as') print(self.user

Windows10环境 搭建Anaconda tensorflow 1.2 修复spyder不能打开的问题

由 随声附和 提交于 2019-12-31 01:33:34
Win10 Anaconda （py3.6） python3.5 + tensorflow 1.2 总算能正常打开spyder了 目前阶段 tensorflow 在windows平台上貌似只支持 python 3.5 的大版本号 目前换个包也就能支持python3.6了，应该不用这么蛋疼了 1、设置安装源 打开Anaconda Prompt 设置输入清华的仓库镜像，第一次添加，第二次移至最优先 conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --set show_channel_urls yes 2、安装TensorFlow 继续打开Anaconda Prompt，输入： conda create -n tensorflow python=3.5 安装完以后，输入： activate tensorflow 激活后，我选择安装的是CPU版本，输入： pip install --ignore-installed --upgrade https://storage

Memory error only in Spyder IDE

问题 doing the following causes a MemoryError in my Spyder Python IDE: >>> from numpy import * >>> a_flt = ones((7000,7000), dtype=float64)+4 >>> b_flt = ones((7000,7000), dtype=float64)+1 Traceback (most recent call last): File "<stdin>", line 1, in <module> MemoryError >>> THis is weird, since the memory usage in the statusbar of Spyder shows that only approx. 25% of my memory is used. Furthermore, when generating even a higher number of these large 7000*7000 arrays in the standard Python IDE
