问题 Over the past couple years I've pip installed lots of things without knowing what I was doing. All of a sudden, I am getting this error when I run a snippet in a Python 2.7 Jupyter Notebook: ImportError: No module named matplotlib When I run this in Terminal: which -a python python 3...

问题 I have previously used Jupyter Notebook (python 2 and 3) on my mac. After not using it for a while, there seems to be a problem I am unable to fix. When starting the notebook from terminal using the command Jupyter notebook , and then select a notebook I want to work with, I get the error: "A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration." I am positive this has nothing

问题 I have two pandas dataframes and I would like to display them in Jupyter notebook. Doing something like: display(df1) display(df2) Shows them one below another: I would like to have a second dataframe on the right of the first one. There is a similar question, but it looks like there a person is satisfied either with merging them in one dataframe of showing the difference between them. This will not work for me. In my case dataframes can represent completely different (non-comparable elements

问题 How do you convert an IPython notebook file (json with .ipynb extension) into a regular .py module? 回答1: From the notebook menu you can save the file directly as a python script. Go to the 'File' option of the menu, then select 'Download as' and there you would see a 'Python (.py)' option. Another option would be to use nbconvert from the command line: jupyter nbconvert --to script 'my-notebook.ipynb' Have a look here. 回答2: According to https://ipython.org/ipython-doc/3/notebook/nbconvert

问题 I'm wondering if it's possible to populate sys.argv (or some other structure) with command line arguments in a jupyter/ipython notebook, similar to how it's done through a python script. For instance, if I were to run a python script as follows: python test.py False Then sys.argv would contain the argument False . But if I run a jupyter notebook in a similar manner: jupyter notebook test.ipynb False Then the command line argument gets lost. Is there any way to access this argument from within
