community_louvain issue: BCTParamError: Modularity infinite loop style G

[AlvaroDeleglise]

Hi,
For some undirected and weighted networks, when I run the community_louvain function an error message emerges: "BCTParamError: Modularity infinite loop style G. Please contact the developer".
Does anyone have an idea how I can solve this?

Here I paste the lines of the function that are causing this problem:

while q - q0 > 1e-10:
it = 0
flag = True
while flag:
it += 1
if it > 1000:
raise BCTParamError('Modularity infinite loop style G. '
'Please contact the developer.')

Thanks in advance.

Sorry for very long delay, I need an example matrix that causes the error.
