问题 I've configured jupyter to be used from a remote computer and set a password to it while initial anaconda setup. Then after fixing this issue, I am trapped in another one. sys.path and sys.executable is incorrect in jupyter , but correct in python and ipython . Please see the details below. Anaconda3 is installed for all users in /opt/anaconda3 and I am using an environment zud for my programs. Background Once the above-mentioned problem is fixed, I tried to import igraph in jupyter but it

问题 Given the following data frame: import pandas as pd df=pd.DataFrame({'A':['$0-$20','$20+']}) df A 0 0−20 1 $20+ How can I get the first value (0-20) to display with the dollar signs, as I originally specified? It actually displays the zero in a strange font and I'm not sure why it works for "$20+" but not "$0-"$20". I've tried: df=pd.DataFrame({'A':[str('$0-$20'),'$20+']}) ...but no dice. Here's specifically what I get: I'm using the Jupyter notebook (Anaconda 3, Python 3.5) Thanks in advance

问题 I have a question on how to programmatically clear\clean the output from all the Cells in my Jupyter notebook after notebook is done loading (when Kernel is ready), and prior to the user, myself, manually executing code. Basically, I would like the notebook to look clean when it is done loading, and I would like to do it automatically. How can I impose a command like clear_output() from a single initialization cell on to all other cells in the notebook? Thank you. 回答1: For a trusted notebook

问题 How is the threshold for scientific notation set in an ipython notebook? I want to set all number outisde of something like [0.01, 100] to be printed in scientific notation, but the threshold seems to be much higher. i.e. In [165]: x = sympy.Symbol('x'); 1.e8*x Out[165]: 100000000.0*x but In [166]: 1.e28*x Out[166]: 1.0e+28*x Because I'm using sympy, I can't send the number to a formatted print statement, i.e. In [167]: print "%.2e" % (1.e8*x) ERROR: TypeError: float argument required, not

问题 I'm experiencing some newly odd behavior from IPython. I just had to do a clean reinstall of my miniconda, so I now have fresh IPython and Matplotlib versions. It turns out that IPython is automatically switching matplotlib to interactive mode (which has the annoying side effect of making my saved figures blank in my scripts, because they save after I close the window). Here's an example: Python 3.7.3 | packaged by conda-forge | (default, Jul 1 2019, 21:52:21) Type 'copyright', 'credits' or

问题 Is there any plotting option in Python (IPython-Jupyter notebook) which accepts generators ? AFAIK matplotlib doesn't support that. The only option I discovered is plot.ly with their Streaming API, but I would prefer not to use online solution due to big amount of data I need to plot in real-time. 回答1: A fixed length generator can always be converted to a list. vals_list = list(vals_generator) This should be appropriate input for matplotlib . Guessing from your updated information, it might
