2017-07-19 06:23:56 +0200 | asked a question | ImportError: No module named I just did a fresh install of fedora 26 (4.11.8-300.fc26.x86_64) and installed a jupyter notebook using pip3 and then installed the sage from the repositories. Upon calling sage I get the following error. Any ideas why this happens and how to resolve this? |

2017-04-14 21:13:55 +0200 | commented answer | networkx can't compute algebraic connectivity Practically speaking, I don't want to compute all the eigenvalues, that's why I'm using networkx's implemented method. |

2017-04-13 03:55:30 +0200 | asked a question | networkx can't compute algebraic connectivity I can compute the algebraic connectivity of the complete graph on 20 vertices in a fraction of a second using However, in a process I generate a graph (on 20 nodes) that I ask networkx to compute its algebraic connectivity, and it keeps running for ever with no errors. Here is the graph: Any reasons why it is so, and any idea on how to fix it? |

2016-08-11 18:29:49 +0200 | answered a question | ImportError: No module named 'sage' As slelievre pointed it out there was a path added to my .bashrc file after installing anaconda. After removing that line sage started working. |

2016-08-11 18:28:19 +0200 | commented question | ImportError: No module named 'sage' Yes, that does it. Anaconda had added a path to my bashrc. After deleting it sage started working. Thanks. |

2016-08-11 00:00:51 +0200 | asked a question | ImportError: No module named 'sage' I had a Sage 6.5 installed from the repository, running on my Fedora 22 nicely. But today when I went to run it I get the following error: I reinstalled Sage, but I still get the same error. Any ideas on why do I get this error and how to resolve it? |

2016-08-02 21:50:21 +0200 | commented answer | latex in plots I didn't know I can use latex command inside a text command. Thanks, that helps. |

2016-06-15 23:05:48 +0200 | asked a question | latex in plots I want to display the formula for the graph of a function that sage has plotted without typing the expression manually, because sage has calculated it. For example the n-th Taylor polynomial expansion of a function: Everything works fine except for two things in the displayed formula: - the * s are shown (which I can live with)
- The two digit exponents are not shown correctly which I assume it is because there are no curly brackets around them in the string g.
P.S. Are there ways of writing up the parts of the text in different colors, without defining two pieces of text and trying to figure out their relative positions? |

2016-04-22 18:11:03 +0200 | commented answer | What's a common way to save and load a list? Thank you very much. Your answer for part b was exactly what I was looking for. Thanks. Still out of curiosity, for a. I get a list that looks like [['1','2'],['3','4']]. Any suggestions on how to avoid going through the whole list and turning strings into numbers? |

2016-04-22 14:18:31 +0200 | asked a question | What's a common way to save and load a list? I have calculated a list through a long calculation to do some other calculations with it. So I saved the list in a .txt file and in the file it looks like this: Now that I want to load it again, I realized that I have to strip the a. How can I save the each element of a list in a line of a file? That is, to get something like: b. How can I save a list (higher dimensional array) into a file and then read it. I tried the following but I seem to be unable to read it: And then to only get |
