问题 I want to teach Python for kids. I want them to use Jupyter Notebook. To avoid the hassle of installation, I want them to use a free online Jupyter Notebook. I thought google's colab (link) and jupyter.org (link) could be best solutions. However, I tried them both and got the error message below: from turtle import * colors = ['red', 'purple', 'blue', 'green', 'yellow', 'orange'] for x in range(360): pencolor(colors[x % 6]) width(x / 100 + 1) forward(x) left(59) TclError: no display name and

问题 I have this formula, I wanted to turn this into pandas calculation, the formula is very easy: NEW = A(where v=1) + A(where v=3) + A(where v=5) I have a data frame like this: Type subType value A NEW X a 1 3 =3+9+9=21 X a 3 9 X a 5 9 X b 1 4 =4+5+0=9 X b 3 5 X b 5 0 Y a 1 1 =1+2+3=6 Y a 3 2 Y a 5 3 Y b 1 4 =4+5+2=11 Y b 3 5 Y b 5 2 Two questions: I know I can just write down the calculation with the specified cell, but I want the code looks nicer, is there other ways to get the value? Because

问题 I'm trying to display a decision tree in Jupyter Notebook and I keep receiving the message: CalledProcessError: Command '['dot.bat', '-Tsvg']' returned non-zero exit status 1 I'm using the following code: from sklearn.datasets import load_iris from sklearn import tree import graphviz from IPython.display import SVG iris = load_iris() clf = tree.DecisionTreeClassifier() fitted_clf = clf.fit(iris.data, iris.target) graph = graphviz.Source(tree.export_graphviz(fitted_clf, feature_names = iris

问题 I'm getting error while connecting the jupyter notebook. It says connecting to the kernel. I'm not able to execute any of the queries in that. Could anyone help me out with this. Below is the error message and logs in anaconda prompt.

问题 In a Jupyter notebook, if I run a cell that takes a long time, I cannot run any other cell until the first cell is computed. Is there a way to tell Jupyter to run a cell in a background process, so that I can continue to run other cells? 回答1: I tried this using Multiprocessing and found it does not work, I've no idea if this is a limitation of Windows or recent Jupyter/Python. So instead I created a solution using Threading, based on this work: https://gist.github.com/maartenbreddels

问题 I wrote a code in python using jupyter notebook and i want to generate an executable of the program. 回答1: You can use this code I've written to convert large numbers of .ipynb files into .py files. srcFolder = r'input_folderpath_here' desFolder = r'output_folderpath_here' import os import nbformat from nbconvert import PythonExporter def convertNotebook(notebookPath, modulePath): with open(notebookPath) as fh: nb = nbformat.reads(fh.read(), nbformat.NO_CONVERT) exporter = PythonExporter()
