ALLHiC_plot : AttributeError

This my command:
ALLHiC_plot -b sorted.bam -a groups.agp -l chrn.list -s 50k -o ./heatmap-pdf

error happened in step2 :Get signal matrix
[17:27:39] Step1: Get chromosome length
[17:27:39] Step2: Get signal matrix
Traceback (most recent call last):

Thank you for your suggestions

Problem had been solved when I installed the "pysam" software.
