Coroutine as background job in Jupyter notebook

由 安稳与你 提交于 2019-12-07 05:30:09
问题 I have a coroutine which I'd like to run as a "background job" in a Jupyter notebook. I've seen ways to accomplish this using threading, but I'm wondering whether it's also possible to hook into the notebook's event loop. For example, say I have the following class: import asyncio class Counter: def __init__(self): self.counter = 0 async def run(self): while True: self.counter += 1 await asyncio.sleep(1.0) t = Counter() and I'd like to execute the run method (which loops indefinitely), while

问题 Here is my setting and this is my script I am trying to use jupyter notebook in pyCharm, but it kept using python2 instead of python3. Any idea about this problem? Add: this pic is running jupyter notebook in chrome. 回答1: My problem was that I had multiple kernels, and PyCharm launches the default kernel. One approach might be to configure PyCharm to specify the kernel of choice to start up, I didn't investigate how to do that. I simply changed the default kernel in Jupyter and this worked

Flush output in for loop in Jupyter notebook

由 [亡魂溺海] 提交于 2019-12-07 03:55:56
问题 I want to print out i in my iteration on Jupyter notebook and flush it out. After the next iteration, I'll print the next i . I tried solutions from this question and this question, however, it just print out 0123...9 without flushing the output for me. Here is my working code: import sys import time for i in range(10): sys.stdout.write(str(i)) # or print(i, flush=True) ? time.sleep(0.5) sys.stdout.flush() these are my setup: ipython 5.1, python 3.6. Maybe, I missed something in the previous

I am using graphviz 0.5 (pip then conda installed), iPython 5.1 , and Python 3.5 The dot file looks correct here are the first characters: digraph

A simple way to view ipython notebook

由 时光总嘲笑我的痴心妄想 提交于 2019-12-06 20:49:09
问题 I am really new to IPython/Jupyter notebook. I just created one notebook (.ipynb) and I want to share it on my webpage. Specifically, I want to add a link, and when people click it, it will open a new "webpage" where they can "view" my code and results. Note: I cannot use github, it is a huge pain for me. I tried nbviewer (http://nbviewer.jupyter.org/). It has several options but only one of them (url) is not related to github/gist. So, in order to have an URL for my file, I uploaded it to

问题 I have jupyter installed with python3.5 on my Mac OSX , but I want the python2.7 version. So, I basically need to uninstall the 3.5 version, and reinstall the 2.7 version.

I tried sudo python3 -m pip uninstall jupyter , and you can see the results below: ✔ ~/current/directory 20:08 $ which jupyter /Library/Frameworks/Python.framework/Versions/3.5/bin/jupyter ✔ ~/current/directory 20:08 $ sudo python3 -m pip uninstall jupyter The directory

How to stop bokeh from opening a new tab in Jupyter Notebook?

由 做~自己de王妃 提交于 2019-12-06 18:50:15
问题 First of all, before this is tagged as duplicate, I have read the other solutions and unfortunately none of them worked for me. My problem is that I want to display a bokeh plot in Juypter Notebook (and only in Jupyter Notebook), not in a new tab/window. In the official documentation here I am told that I only need to change output_file to output_notebook Even though the plot is now displayed inline if I do that, bokeh won't stop also opening a new tab and needlessly displaying the plot there
