Cannot import name 'ChainMap"

[pedroleao2]

Hi. I'm having a problem. When I try to run my command (python3 PlasForest.py -i /home/pedro/Guaymas_C/Analyses/GuaymasC.fasta) or the test_plasforest.sh script, I receive the same error:
I'm using Python version 3.6.0

Traceback (most recent call last):
