첫 번째 신경망 훈련하기: 기초적인 분류 문제  |  TensorFlow Core

AttributeError: module 'tensorflow' has no attribute '__version__' 에러 해결

 

Tensorflow의 기초 예제, 패션 MNIST 분류 튜토리얼 수행 중 발생한 문제를 해결한 내용을 공유합니다.

대부분 이런 에러는 버전 문제 혹은 관련 라이브러리 의존성 때문이었다.

이번 경우는 어땠을까?

해당 부분에서 본인의 OS버전에 맞는 것을 설치해주길 바란다.

설치하고 재부팅했더니,

Tensorflow버전이 설치된대로 잘 보인다!

성공적으로 돌아가고 있다.

항상 사소한 문제 해결부터 쉽지 않은 것이 언제 고수가 될랑가 싶다.
