ERROR: Could not find a version that satisfies the requirement tensorflow - python3.8

tensorflow를 하기 위해 설치를 했습니다.

왠 pip 설치에러???

그런데 위와 같은 에러가 발생하였고 버전이 맞지 않는 문제가 발생하였습니다.

(venv) D:\work\ml-tf>pip install tensorflow
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow

(venv) D:\work\ml-tf>python --version
Python 3.8.2

(venv) D:\work\ml-tf>pip list
Package    Version
---------- -------
pip        20.0.2
setuptools 41.2.0

Python과 Tensorflow간의 버전이 맞지 않아서 패키지 설치가 되지 않았습니다. 현시점에서 파이썬은 3.8.2 가 최신버전이고 64bit 버전인 상황이고 텐서플로우는 2까지 나와 있지만 그냥 1 버전부터 다시 익혀보려고 설치한 건데 안되네요.

공식 홈페이지를 살펴보고 다른 사람들의 글을 봐도 처음에는 왜 안되는지 몰랐습니다. 그러다 자꾸 보다보니....

3.7까지? 설마 3.8 너무 최신이라서 안되는건가?

시스템 요구사항에서 3.7까지 언급되어있길래 Python을 다시 3.7.7 x64 버전으로 설치하였습니다. 그랬더니 성공!

tensorflow 1.14 설치했는데 뭔가 패키지가 많이 깔렸습니다. tensorflow 2.1이 나온 시점이지만 배우는 차원에서 1.14로 설치해보았습니다.
