Hi, I was trying to add this package to conda-forge but I just realize there is no license file in this repo. Do you mind to add one? It looks to me you could add something like this if you want a MIT license

It would be nice to have clear guides for how to build, test, and PR each package. These instructions could include:

• How to install from source,
• how to test,
• how to build and check the documentation,
• how to submit a pull request and ask for a review.

Kepler Mapper has a small instruction doc, this should be replicated, expanded, and standardized across each package.

Hi

First of all, thanks for building this application. I've seen previous issues been posted before that were similar but I really wasn't able to figure it out. I get the following error trying to install scikit-tda:

Since I read the previous similar issues. I have tried to install previous versions of pip (19.0.0.1, 20.0) and different versions of python (3.6, 3.7, 3.8. 3.9). I have tried installing it on the root and in virtual environments (anaconda, pycharm). I have tried to disable pep517 with the following command python -m pip install --no-use-pep517 ripser

I really don't know what to do at this point. I must say that I am pretty unfamiliar with git. Any help would be appreciated.

KR

Hello,
I am able to apply the codes of the "Representative Cocycles" page on python successfully. However, I am more interested in having the cycles (cocycles) of dim.3 barcodes. Is there a possibility to help me in modifying the code that plots the cocycles. i.e. the function
plotCocycle2D(D, X, cocycle, thresh) to accept a 3D point cloud and plot its cocycles of dim.3. I would highly appreciate it.
I have tried but unfortunately, it did not work out for me.
Many thanks in advance

The docs are currently failing to build. The conf.py file contains some deprecated code that needs to be fixed.

This might also be a good time to update the docs with some additional tutorials (#27), a "Getting Started" section (#23), and some sample outputs (#12).

Hello, how to use scikit-tda to process the MNIST handwritten dataset，Is there any code for this

Hi,

Do you have any example with time-series data ?

Thanks

Hi,

Is there a way to create 1-dimensional persistence diagram using sublevelset filtration or lower star filtration on image data? I think it is not possible to construct 1D PD with lower_star_img. Currently, I am able to construct 0D PD using lower_star_img, but I can't find a way to make 1D PDs. Any help would be greatly appreciated.

Thank you.

Each project has a set of example scripts, it looks like Sphinx-gallery makes displaying rendering these examples look very nice.

I'd like to spend some time designing the organizational structure of this project. Currently, each subproject exposes the defined methods on their own, and sktda simply imports all of them. Even then, the current suggested API is to use each package as a stand-alone tool. We could reorganize this project better so it is more cohesive.

The issue currently is that each package stands mostly alone. This is nice because we can develop them all independently and it is straight forward to add new modules to the system. It can be confusing though as there is some repetition between packages and each has its own name. It would make more sense for everything to be logically indexed under sktda based on uses rather than grouped under each individual library based on historical reasons.

Possible structure

One option would be to structure similar concepts together. We have ripser.py and Cechmate for persistent homology, kmapper for mapper, persim for working with persistence diagrams (and hopefully soon having distances on mapper as well. There are also visualization tools for both diagrams and simplicial complexes (mapper visuals).

We could have ~4 modules:

• sktda.persistent_homology: exposing everything in ripser.py and cechmate at the same level.
• sktda.mapper: exposing kmapper
• sktda.distances: exposing half of persim
• sktda.plotting: exposing the other half of persim and some of kmapper

Does anyone have thoughts on this?

how to install on windows?
can you put it to conda forge
then instalation will be easy like http://gudhi.gforge.inria.fr/
conda install -c conda-forge gudhi

do you have video how to use it?

Code in docs/_static, docs/_templates, and docs/theme_settings.py should be packaged into a sphinx extension.

This will make it easier to sync documentation configurations across all the scikit-tda packages.

it seems we need the invited link to join in......

Each of the major projects could benefit from an increase in the code coverage. Granted, this is not a great metric to track, getting them all to a baseline would help. This is a pretty open ended issue, so let's try a first baseline of 80%.

In addition to the promised tutorials for this software package, a short "Getting Started" section would help me understand how to use this software package.

Hi everybody,

I have seen a ton of codes to compute a persistence diagram when the input data is a point cloud. Is there a way to compute the persistence diagram for a filtration of a clique complex if the input data is a weighted graph? It cannot be done with the Ripser library right? Any code would be very much appreciated.

Thank you.

If you install Cython first and then install scikit-tda no error is encountered. In this case running pip install -r requirements.txt also works as Cython is already installed in the second round.

Similarly numpy needs to be installed beforehand to avoid this error:

Workaround

Installing scikit-tda after installing those two dependencies works fine. So removing scikit-tda from the requirements.txt and executing pip install scikit-tda>=0.0.3 afterwards works perfectly well.

Dockerfile for reproduction

FROM python:3.8

RUN pip install --upgrade pip

COPY requirements.txt /tmp/requirements.txt
RUN pip install -r /tmp/requirements.txt

I'm looking to view your documentation on your website scikit-tda.org and the site appears to be down. I've tried multiple browsers, computers and ip addresses, but no luck.

As the Google Image search for "topological data analysis" shows.
Thanks!

I tried installing this package on jupiter notes but had an error. could someone suggest a solution to me? find below the result after entering
