index 0 is out of bounds for axis 0 with size 0

[jorrgi]

When I run the code on a bigger amount of data, it either gives an error or the results are not so adequate. Any idea what I can do to make it work?

I got the same issue ... but it is a very small dataset, with 24 value 1-D array ....

IndexError: index 0 is out of bounds for axis 0 with size 0

Seems getting "index 0 is out of bounds for axis 0 with size 0" as left_touchpoints is [], so even index 0 will cause out of bound.

and the underlining reason is wrong input data format, dip_fn expected a list of observed data point [0, 1, 1, 0 ,0 ,2 .... ] , but not frequency of each observation ....

It seems this is related to the smoothness of the data... when I smoothed the data log scale the error disappeared
