1.创建虚拟环境 tf
conda create --name tf python=3.6
2.激活进行 tf
conda activate tf
3.安装 tensorflow
conda install tensorflow==1.14.0
这里需要注意的是版本，mac 可能不支持这么高的版本，直接安装 tensorflow==1.5 成功率可能更高。
之前我是用 pip 安装 tensorflow ，但是虽然成功安装，import 的时候总是会报错，所以就改用 conda 安装了
4.在 python 环境中导入 tensorflow 报错如下
import tensorflow
/Users/wys/opt/anaconda3/envs/tf/lib/python3.6/site-packages/tensorflow/python/framework/dtypes.py:516: FutureWarning: Passing (type, 1) or '1type' as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / '(1,)type'.
_np_qint8 = np.dtype([("qint8", np.int8, 1)])
/Users/wys/opt/anaconda3/envs/tf/lib/python3.6/site-packages/tensorflow/python/framework/dtypes.py:517: FutureWarning: Passing (type, 1) or '1type' as a synonym of type is deprecated; in a future version of numpy, it will be understood as (type, (1,)) / '(1,)type'.
_np_quint8 = np.dtype([("quint8", np.uint8, 1)])
。。。
需要安装新的 numpy
pip3 install numpy==1.16.4
5. python 环境中重新导入 tensorflow 成功
