I have not yet benchmarked it but am working on it, however it is
definitely slower in comparison to Ripser / gudhi and co. (although if I
understand correctly Ripser only computes homology for Vietoris-Rips
complexes?), since it is a very direct python implementation of
Zomorodian's algo with
Great to see that you've added to Zomorodian paper! Have you done any
benchmarking of this yet? In the end I used Ripser++ (
https://github.com/simonzhang00/ripser-plusplus) which worked relatively
well, but it seems to me that the current opinion in the field is that some

Hello all,
I know I am a bit late to the party, but I have written a Sage module for
computing persistent homology, and I just submitted a ticket !

Ah ok, it may be the case that working with the R interface and using
TDAstats (https://cran.r-project.org/web/packages/TDAstats/index.html) might
now be the best solution, but I may comment on this again when I have
landed on what I will use.

No, I do not believe so.

I am just starting a project involving persistent homology, did anything
end up happening with this?

There have been major CoCalc changes since the successful
installation I reported three weeks ago. Notably, CoCalc projects
now run under Ubuntu 16.04.3 (vs

I imagine that interoperability with Sage will need Python2.

Thank you so much!! I'll try all of that when I have time (next week). I
had tried to compile on cocalc (then SMC), i got some error messages,
mentioning Qt among other things.
a couple of questions:

I am in contact with the author of dionysus, who expressed the interest of
it to be added to Sage.
(he is releasing a new version soon, which is easier to install apparently)

Thanks everyone for the answers. If i ever reach the stage when i can run
gudhi on some computer, and then the stage when i can install it on my own
computer, then i'll contemplate the project of writing an interface to sage
