keras를 깔아서 연습해보고 싶은데 keras 모듈을 import 하려면 자꾸 scipy 에서 import 오류가 뜹니다 ㅜ

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm Community Edition 2018.2\helpers\pydev\pydevd.py", line 1664, in <module>

이것이 오류 메시지의 전문입니다. tensorflow, numpy 는 정상 작동하는데, keras를 import 하려고 하기만 하면 저 메시지를 띄우며 안되네요. 도와주세요 ㅜㅜㅜ
