Atom: Setting up Hydrogen Launcher for use with Python 3.7

由 无人久伴 提交于 2021-02-08 09:08:16
问题 I am trying to set up Atom to be able to run Python code interactively and on a line-by-line basis, and have been trying to work with Hydrogen and its associated packages to that end. The Hydrogen package is working properly as intended, as I'm able to run the script on a cell-by-cell basis, and am able to choose which Python kernel to run the script with. However, the problem starts when I try to run it with Hydrogen Launcher, which is supposed to enable you to launch Jupyter consoles

Setting up Hydrogen and Atom with Anaconda managing python installation

由 偶尔善良 提交于 2021-02-07 09:52:35
问题 I have added my python 3 executable to the system PATH (against the advice of Anaconda) to try and get Hydrogen (and really any Atom extension/plugin) to run lines or blocks of code in Atom. The 'scripts' atom plugin appears to work (I select some code and enter ctrl-shift-b ), but I'd love to use more of the features in Hydrogen. When I execute (for example): print('hello world') I get the following error: Python 3 Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\runpy

Giant IPKernelApp Error Using Hydrogen in Atom

问题 Starting a few days ago, after months without issue, I began having a giant error box keep popping up when editing my code in Atom. I believe it is from the Hydrogen plugin, the weird thing is even with this error the code still runs and does what I want it too. I created a new conda environment, installing only what I needed (pandas, geopandas, descartes, jupyter) and even when using the new environment in Atom I am getting this issue. I've tried upgrading ipykernel but it is already the

多线程-1117

规律： 多线程协作中，一般被考虑使用的，无非就是： (同步工具类) Semaphore ( semaphore.acquire() ;消耗许可数,许可数为负数时，当前线程将被阻塞 semaphore.release() ;增加许可数 ) CountDownLatch ( countDown.countDown() 初始值减1,当前线程总是不会被阻塞 countDown.await() 若值不为0则会被阻塞，等待初始值减为0才会恢复 ) CyclicBarrier ( cyclicBarrier.await() 初始值减1,并阻塞等待初始值减为0。最后一个线程将它减为0之后,若有指定任务,则还需要负责执行指定任务完毕,之后会唤醒之前被阻塞的所有线程，并重置为初始值。 有两个构造方法，其中一个构造方法可以指定每次最后一个线程，需要执行的额外任务。 cyclicBarrier.reset() 用于提前唤醒被阻塞的线程,并重置为初始值 ) (原子变量类) AtomicInteger 一般用于无锁进行自增计数情形 (锁) volatile + ( ReentrantLock + Condition ) / s ynchronized 通过 condition.await()/condition.signal() 或者 object.wait()/object.notify() 的 挂起

Setting Up a Python Virtual Environment with Hydrogen in Atom

由 孤街醉人 提交于 2020-08-05 17:26:57
问题 I'm in the middle of switching from VS Code to Atom and I'm trying to set up a virtual environment for my python project. It was pretty easy to do in VS Code, I'd run the following script and it would automagically start using the new env (with all the required packages) when I'd run the script: python3 -m venv my_env source my_env/bin/activate pip3 install -r requirements.txt Now I'm trying to set up Hydrogen to work the same way. When I run lines of code inline with Hydrogen, I want them to

线程协作工具之Semaphore、CountDownLatch、CyclicBarrier

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 各种线程协作工具 常见线程协作工具： 读写锁ReadWriteLock 信号量Semaphore 倒计时门栓CountDownLatch 循环栅栏CyclicBarrier 线程本地变量ThreadLocal 主要讲信号量Semaphore，倒计时门栓CountDownLatch， 循环栅栏CyclicBarrier 然后根据两个LeetCode题目来应用一下。 第一题： 三个不同的线程将会共用一个 Foo 实例。 线程 A 将会调用 one() 方法 线程 B 将会调用 two() 方法 线程 C 将会调用 three() 方法 请设计修改程序，以确保 two() 方法在 one() 方法之后被执行，three() 方法在 two() 方法之后被执行。 原生解法 应用场景及用法 基于notify/wait，所有的线程间通信类似通知的机制本质上都是notifyAll，多能用这个来实现。 class Foo { private static AtomicInteger flag = new AtomicInteger(0); private static Object Lock1 = new Object(); public Foo() { } public void first(Runnable

Jupyter Notebook can't find modules for python 3.6

由 大憨熊 提交于 2019-12-11 16:56:39
问题 Not sure what happened but whenever I use ipython, hydrogen (atom) or jupyter notebook can't find any of the installed modules. I know I have pandas installed but the notebook says its not found. I should add that when I run the script normally ( python script.py ) it does import without any errors. Suggestions? Thanks! 回答1: Try the following: pip3 install ipykernel --upgrade python3 -m ipykernel install --user Make sure that Panda is installed using pip3. 回答2: Issue seems to be resolved by

Adding New Conda Env to Hydrogen for Atom

由 大兔子大兔子 提交于 2019-12-04 13:31:41
问题 I work with many conda environments in my workflow and like to use the hydrogen package for the Atom Editor when I am exploring objects. However I always forget how to add a new jupyter kernel to the new environments even though it is only two lines of code. What are those lines of code? 回答1: Here is the link to the github issue where the comment is answered. The two lines of code to be run in your terminal are these: source activate YourEnvNameHeRE python -m ipykernel install --user --name

Using anaconda environment in Atom

由 爱⌒轻易说出口 提交于 2019-12-03 03:15:38
问题 I've install Anaconda (Python 3.6) and tensorflow (python 3.5). I've managed to get it run both on Spyder and on sublime text 3( by making new build system). Now all the is using Atom( which I'm not used to). So I've trying to "tell" Atom to use python in the following folder: C:\users\engine\anaconda3\envs\tensorflow\python.exe without any success, any idea how to do that or what kind of package should I use( I'm using windows so virtualenv) thanks in advance ! 回答1: In your Anaconda terminal
