That's a remarkably weird bug

What's the bug about?
from neurolib.

remember dpath library? it's the thing that allows searching in dict keys with star notation (e.g. *tau).. so when a numpy array which dtype is int is a value inside the dictionary, it fails... actually I guess that is the bug in the dpath library... however, it's very easy to overcome this by forcing all numpy arrays (so connectivity and delay matrices) to float (and they typically float)...

It seems weird that it depends on the value inside the array. Force-converting user-defined values is the most elegant solution but I guess it works until it doesn't :))
Can you post / reproduce the error?

setup:
from dpath.util import search
import numpy as np
dct = {"aln.t.a": 12.0, "aln.t.b": 32., "aln.conn": np.array([[1, 1]])}
# first arg is to search where, second is what to search (using star notation), third is the separator in keys (dot by default)
list(search(dct, "*a", "."))leads to:

TypeError: object of type 'numpy.int64' has no len()
however:
# note floats inside np.array
dct = {"aln.t.a": 12.0, "aln.t.b": 32., "aln.conn": np.array([[1.0, 1.0]])}
list(search(dct, "*a", "."))leads to correct result
[('aln.t.a', 12.0)]

one of the weirdest I ever encountered!

it's deep inside dpath and relates to how dpath create segments (which is one of the building blocks of the whole machinery)
