Seg Fault when try to use Graph Module

[nhvanlie]

Hello, I installed pyGATB using pip and python v3.5.6 on our cluster. I was playing around with the data and while I could reproduce the sample code for the Bank module, the code kept causing a segmentation fault when I tried to read the data into Graph (whether it was a h5 or fastq file):

~/gatbTest$ python

>>> from gatb import Graph
>>> graph = Graph('-in ./celegans_reads.h5')
Input is h5 or _gatb/ (we assume that kmer counting has already been done), we will complete it into a graph if necessary.
Segmentation fault
