Hi Dimitriy and Kowshik, You are right. If I deleted [1,1] and [2,2]. The code is able to run without any problem. The filtration comes from a function on graphs. [1,1] and [2,2] corresponds to two se

Runtime error when computing persistence diagram
Hi Dimitriy, Thanks for quick reply. It seems that this problem is system dependent. I tried running on the same code on Ubuntu at different versions of Dionysus, it throws the same error(RuntimeError

Runtime error when computing persistence diagram
Hi Dimitriy, I have been used Dionysus to compute the persistence diagram for a long time. But recently I encounter a strange runtime error. Here is a small example that is able to reproduce the error

Computing extended persistence in dionysus2
Thanks a lot for response. I tried to translate from your example to Dionysus2 and I almost get it but because API for init_diagrams in two versions are different, I fail on the last step. I try to ca

Hello Dmitriy, I am trying to compute extended persistence for graphs using dionysus2. I found in dionysus1 there is a file called 08extendedpersistence.py in the accomapnying examples. But I am not

gpu implementation of persistence computation
Hello, This is maybe not very relevant but I still want to post the question here. Since the major computation of persistence diagram boils down the Gaussian elimination of boundary matrix, should GPU

Computing persistence diagram in parallel
Hi Dmitriy, Thank you very much. The quick fix works well. But after computing n diagrams, I want to compute a n*n distance matrix in parallel. As you mentioned, the persistence diagrams are not pickl

Computing persistence diagram in parallel
Hi Dmitriy, I am trying to compute persistence diagram for different graphs in parallel in python2. I use joblib to do multiprocessing computation. Here is a toy example: def computePD(i): import dion

Bottleneck distance is not symmetric
The unsymmetric example I found is run on Ubuntu with d.__version__ 2.0.6.dev0 in python2. I tried the same code on mac with d.__version__ 2.0.5 in python2 and got the same result with Dmitriy. Best,

Bottleneck distance is not symmetric
Hi Dimitry, I found that the bottleneck distance is not symmetric, although the difference is not significant. import dionysus as d dgm1 = d.Diagram([(8.04545,4.59091), (5.5,4.68182)]) dgm2 = d.Diagra
