ubuntu18.04安装tensorflo后，import tensorflow出现/usr/local/lib/python3.6/dist-packages/tensorflow/python/

问题：import tensorflow 之后出现这些提示符
/usr/local/lib/python3.6/dist-packages/tensorflow/python/framework/dtypes.py:493: 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)])

等等；

原因是：numpy版本太高了（in a future version of numpy) 我的numpy是1.17.1，我把版本降低到1.15.0

解决办法： 先卸载numpy： sudo pip3 uninstall numpy
再安装比较低的版本： sudo python3 -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numpy==1.15.0
