如何在Mac上安装TensorFlow

如题：如何在Mac上安装TensorFlow

按照搜索出来的中文教程没有安装成功的，后来在youtube上有一个叫Jeff heaton（你没看错，不是那个Geoffrey Hinton）的教授发布了教程2020, Installing TensorFlow 2.0, Keras, & Python 3.7 in Mac OSX按他说的一步一步来，安装成功了。

1、 点击下载minconda

如下图，选择红框中的版本，一步步安装就可以。

选择红框中的版本

2、通过conda安装Jupyter

terminal里输入：
conda install jupyter

3、下载环境安装脚本

github上搜索Jeff heaton,找到 t81_558_deep_learning仓库，划到最下方找到tensorflow.yml，用浏览器打开后点击保存在你用户名的文件夹下。

4、创建环境

terminal里输入：
conda env create -v -f tensorflow.yml
输入后正确的显示如下：

这时候等待即可。
注意上面吧的命令不要输错了，我当时输入成：
conda create -v -f tensorflow.yml
结果一直显示：

Traceback (most recent call last):
  File "/Users/leo/opt/miniconda3/lib/python3.7/site-packages/conda/exceptions.py", line 1079, in __call__
    return func(*args, **kwargs)
  File "/Users/leo/opt/miniconda3/lib/python3.7/site-packages/conda/cli/main.py", line 84, in _main
    exit_code = do_call(args, p)
  File "/Users/leo/opt/miniconda3/lib/python3.7/site-packages/conda/cli/conda_argparse.py", line 82, in do_call
    return getattr(module, func_name)(args, parser)
  File "/Users/leo/opt/miniconda3/lib/python3.7/site-packages/conda/cli/main_create.py", line 23, in execute
    raise CondaValueError("The target prefix is the base prefix. Aborting.")
conda.exceptions.CondaValueError: The target prefix is the base prefix. Aborting.

5、检查TensorFlow的命令行

terminal里依次输入：
conda activate tensorflow
python
import tensorflow as tf
print(tf.__version__)
输出结果应该为2.0.0
