jupyter-lab

问题 I am new to jupyter notebook,what is the key difference between the jupyter notebook and jupyter lab,suggest me to choose the best one,which should be used in future. 回答1: Jupyter Notebook is a web-based interactive computational environment for creating Jupyter notebooks documents. It supports several languages like Python (IPython), Julia, R etc. and is largely used for data analysis, data visualization and further interactive, exploratory computing. JupyterLab is the nex-generation user

问题 I'm trying to get text to display as bold, or in colors, or possibly in italics, in ipython's qtconsole. I found this link: How do I print bold text in Python?, and used the first and second answers, but in qtconsole, only the underlining option works. I try: print '\033[1m' + 'Hello World!' + '\033[0m' And get: Hello World! (No boldface). The colors don't work either. But: print '\033[4m' + 'Hello World!' + '\033[0m' And get: Hello World! With underlining. This is only in the qtconsole.

问题 I am plotting a complex interactive donut chart in bokeh. The code below is a simplification of a component of this chart. I have a function which compiles a dataframe of data for the donut, and then converts it to a CDS. This data is then plotted as annular wedges. A radiobutton group should trigger a switch to a different dataframe (as CDS), and replot the annular wedge glyphs. The example provide (for Jupyter Lab) works in one direction. When initially plotted the button.active == 0 (outer

问题 I am running jupyterlab within jupyterhub on kubernetes. I am trying to display widgets using e.g. from ipywidgets import interact @interact(x=(0, 100, 10)) def p(x=50): pass Instead of the intended interactive widget, the lab notebook prints: interactive(children=(IntSlider(value=50, description='x', step=10), Output()), _dom_classes=('widget-interact... On inspection of the javascript console: default.js:129 Error: Object 'jupyter.widget' not found in registry at default.js:1474 at new

问题 I'm not sure if this is a CV question or SO, so I apologize if it falls within the CV domain. Problem I know it's possible to microbenchmark specific chunks of R code, but is there any benchmark-ing tool for an entire Jupyter Notebook? I could just run the entire notebook and time it manually, but I'd like more statistics and precision on the timing for which the microbenchmark package provides (I'm trying to make a case for automation of data analyses and visualizations). The other dilemma

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
