Split method does not work in Python module

[GabrielMoralesTello]

This is the script:

from amas import AMAS
sequences_path = './concatenated_alignment_copy.phy'
partitions_path = './partition_scheme_2.txt'
meta_aln = AMAS.MetaAlignment(in_files=[sequences_path], data_type="dna", in_format="phylip", cores=10)
parsed_parts = meta_aln.get_partitions(partitions_path)
partitions = meta_aln.get_partitioned(partitions_path)

The function meta_aln.get_partitioned(partitions_path) gives me the following error:
AttributeError: 'MetaAlignment' object has no attribute 'remove_empty'
