amazon linux2で何としてもPolyglotを動かしたい

$ sudo yum install python3-devel
$ pip3 install pyicu
$ pip3 install pycld2
$ pip3 install morfessor

$ python3 app.py
Traceback (most recent call last):
File “app.py”, line 3, in
from polyglot.detect import Detector
File “/home/vagrant/.local/lib/python3.7/site-packages/polyglot/detect/__init__.py”, line 1, in
from .base import Detector, Language
File “/home/vagrant/.local/lib/python3.7/site-packages/polyglot/detect/base.py”, line 11, in
from icu import Locale
ImportError: cannot import name ‘Locale’ from ‘icu’ (/home/vagrant/.local/lib/python3.7/site-packages/icu/__init__.py)

何故だ?
とりあえずnltkを使うか。。。
