yum install xz-devel 
yum install python-backports-lzma

pip3 install scikit-image

pip3 install backports.lzma

/usr/local/python3/lib/python3.6/lzma.py

将
from _lzma import *
from _lzma import _encode_filter_properties, _decode_filter_properties
给为
try:
 from _lzma import *
 from _lzma import _encode_filter_properties, _decode_filter_properties
except ImportError:
 from backports.lzma import *
 from backports.lzma import _encode_filter_properties, _decode_filter_properties

ModuleNotFoundError: No module named '_lzma'
