问题 I isolate my data science projects into virtual environments using pipenv . However, running a Jupyter notebok does not access the local environment and uses the default IPyKernel. I've seen that you can register virtual environments from within the environment, but this requires installing the ipykernel package which itself requires Jupyter! Is there anyway to avoid this and just use a single Jupyter install for all virtual environments? 回答1: Generally, you'd install jupyter once and do the

问题 I am writing descriptive ipynb file and need to give output in markdown with space, but unable to add tab space for printing structured data. 回答1: Type "nbsp" to add a single space. Type "ensp" to add 2 spaces. Type "emsp" to add 4 spaces. Use the non-breaking space (nbsp) 4 times to insert a tab. eg.  This is an example. 回答2: If I understand your question then I don't think this has anything to do with Jupyter cells. For example, are you able to type a tab key into a Stackoverflow question

问题 Jupyter has a feature in being able to execute one cell at a time. If a cell has a lot of statements it's often possible (desirable) to split it into smaller single statement cells, except when a block is involved,e.g if, for, def, etc. this question was asked earlier in a different way: Execute algorithm step by step in Jupyter and answered What is the right way to debug in iPython notebook? While invoking a debugger may be the best option available, it does seem kludgy, and it likely would

问题 I have a dataframe say dfdata in a jupyter server notebook running on a remote machine) . I want to access the dataframe in the remote machine memory to my local machine, say to paste the dfdata to Excel. Normally (when the notebook server is running locally), I do dfdata.to_clipboard() to copy the dataframe to clipboard and now able to paste it to Excel. However, since the dfdata is now on the remote machine, the dfdata.to_clipboard() does not have the copy of the dataframe in clipboard. How

问题 I have the following snippet in the first cell of a Jupyter notebook: import matplotlib.pyplot as plt import pandas as pd import ipywidgets as widgets import numpy as np out = widgets.Output() data = pd.DataFrame(np.random.normal(size = 50)) plt.ioff() with out: fig, axes = plt.subplots() data.hist(ax = axes) display(fig) plt.ion() display(out) If I restart the kernel and run this first cell, I see this output: <Figure size 640x480 with 1 Axes> However, if I run this first cell a second time,

I have logging set as: import logging logging.basicConfig(format='%(levelname)s : %(message)s', level=logging.INFO) logging.root.level = 20 But when I then call: logging.info("hello world") It does not print anything in the output cell. It just prints out the stuff in the console in
