MAC installation tensorflow

Install tensorflow on mac for the first time

Because the anaconda installed on the computer is python3.9 version, the subconsciously installed tensor flow definition python version is 3.9 (there is a pit here)

## terminal command
`conda create -n tensorflow python=3.9`

The second step is to activate the tensor flow environment

#Terminal command
conda activate tensorflow

The third step is to install tensor flow (the problem is coming)

#installation command
conda install tensorflow

The error is as follows, probably saying that python version 3.9 is not supported, and the supported versions include 2.7, 3.7, 3.6, 3.5

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - tensorflow -> python[version='2.7.*|3.7.*|3.6.*|3.5.*']

Your python: python=3.9

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 condawill not
change your python version to a different minor version unless you explicitly specify
that.

The fourth step is to downgrade the python version, I changed it from 3.9 to 3.6
