TypeError: unsupported operand type(s) for +: 'int' and 'str'

I ran the following to generate the Species Tree:

python3 Zombi.py Ti species.tre output

where species.tre is the following:

(DUMMY:1,(((1:0,2:0):0,3:0):0,4:0):1);

I then ran the following to try to get a Gene Tree:

python3 Zombi.py G params.tsv output

where params.tsv is the following (tabs instead of spaces):

DUPLICATION 0
TRANSFER 0
LOSS 0
INVERSION 0
TRANSLOCATION 0
ORIGINATION 0
INITIAL_GENOME_SIZE 1
VERBOSE 0

I got the following error:
