tensorflow를 다운하기 위해 

conda install -c conda-forge tensorflow 

를 적고 실행하였는데

UnsatisfiableError: The following specifications were found

to be incompatible with the existing python installation in your environment:

Specifications:

  - tensorflow -> python[version='3.5.*|3.6.*|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|3.7.*']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for.

When python appears to the right, that indicates that the thing on the left is somehow

not available for the python version you are constrained to. Note that conda will not

change your python version to a different minor version unless you explicitly specify

that.

이런 형식으로 뜨는데 파이썬을 다운그레이드 하고 CUDA를 깔란것이 맞나요?

영상에서는 특별히 더 까는것이 없었는데  어딘가 잘못된건가요?
