[python]AttributeError: 'Tensor' object has no attribute 'numpy'

 

파이썬에서

TensorFlow 2 하다가...

문서 내에서

#Tensorflow 2 설치 후 Tensorflow 2 사용
import tensorflow.compat.v1 as tf1

tf1.disable_v2_behavior() #tensorflow version 2를 사용 안 하겠다.

를 수행? 실행시켰기 때문에 이 문서 내에서는 더이상 Tensorflow2의 것들을 사용할 수 없음.

 

 

-> 새로운 문서에서

Tensorfow2를 import하고 안의 속성들을 사용하면 됨.
