问题 I am trying to write a gui for launching from an ipython/jupyter notebook but am running into trouble using tkinter from the notebook, especially in getting the tk gui window to close gracefully. What are best practices for how to make/launch a tkinter gui from jupyter and then close it without killing the ipython kernel? This is my first time trying to use tkinter. I found a lot of detailed info about how to do this with older ipython versions (e.g., iPython 3.2), but not as much for more

问题 When I create a virtualenv, it installs setuptools and pip. Is it possible to add new packages to this list? Example use cases: Following this solution to use ipython in virtualenv (from this question) requires installing ipython in every virtualenv (unless I allow system-site-packages). Or if I'm doing a only flask/pygame/frameworkp development, I'd want it in every virtualenv. 回答1: You can use bootstrap scripts to do whatever you want See https://virtualenv.pypa.io/en/latest/reference.html

问题 I can register a handler to button.on_click in ipython notebook widgets, but I don't know how to do the same for a dropdown widget import ipywidgets as widgets from IPython.display import display def on_button_clicked(b): print("Button clicked.") button = widgets.Button(description="Click Me!") display(button) button.on_click(on_button_clicked) But for choose_task = widgets.Dropdown( options=['Addition', 'Multiplication', 'Subtraction'], value='Addition', description='Task:', ) there seems to

问题 I have python code spanning several files which I packaged up for convenience, ending up with the following 3 files under my_package directory: __init__.py contents: from file1 import * from file2 import * file1.py contents: class Base(object): pass file2.py contents: from file1 import Base class Derived(Base): def __init__(self): return super(Derived, self).__init__() I then execute in IPython: >>>%autoreload 2 >>>import my_package >>>t = my_package.Derived() So far so good. But then I make

问题 I have an Ipython Jupyter kernel running on in an AWS VPN that I tunnel to a port my laptop where I connect to with a browser. I am finding that the kernel dies whenever I lose the tunnel and I have to run my notebook from the beginning. What is the likely cause of this and how can I prevent it? It is only the notebook kernels that die, the notebook server stays up. 回答1: I admit that this seems odd. I wonder if there is something in the notebook that is killing the kernel. This can happen.

问题 Is there a way to write a cell magic that knows the input number of the cell? By "input number" I mean the ? in the cell's In[?] prefix. At first glance, it seems that IPython.core.magic.cell_magic only knows about the cell content -- it there any way to go beyond that? 回答1: This information is provided by the execution_count of the current instance of the IPython shell, that can be obtained with get_ipython : print(get_ipython().execution_count) 来源： https://stackoverflow.com/questions
