Accelerate speed ?

[orena1]

Hi,
Thanks for the tool, it is very good!
I wonder if there is any way to increase its speed? maybe you can share any tips?
here is the file:
ezyzip.zip

I used this code:

pickle.load(open(..pkl,'rb'))
from stracking.linkers import SPLinker, EuclideanCost
euclidean_cost = EuclideanCost(max_cost=100);
my_tracker = SPLinker(cost=euclidean_cost, gap=3);
tracks = my_tracker.run(particles_all);

BTW, most of the time is on

stracking/stracking/linkers/_sp_linker.py

Line 114 in 52db3a0

dist_matrix, predecessors = bellman_ford(csgraph=graph,

I managed to make it much faster using graph-tool, reduced from more than 2 hours to a couple of minutes
