树莓派想跑个TensorFlow，结果发现各种安装包错误，各种解决，下面是一些问题的解决和解决方法。
问题三是打印Hello时输入import tensorflow as tf执行完第一句遇到的
问题一：
ERROR: Cannot uninstall ‘wrapt’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
解决办法一：
1.
pip3 install -U --ignore-installed wrapt enum34 simplejson netaddr
解决方法二：
针对润国说，确信自己装的包没问题，那就用
--ignore-installed <红色标注的包>忽略掉即可
eg：sudo pip3 install <源包> --ignore-installed <红色标注的包>
问题二：
ERROR: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: ‘/usr/local/lib/python3.5/dist-packages/wrapt-1.11.2.dist-info’
Consider using the `–user` option or check the permissions.
解决办法：
在正常的命令后面加一个 --user即可
eg：pip3 install -U --ignore-installed wrapt --user
问题三：
Traceback (most recent call last):
File “/usr/bin/pip3”, line 9, in
from pip import main
ImportError: cannot import name 'main’
解决办法：
1）执行命令：sudo vi /usr/bin/pip3 （如果是pip就把路径的pip3改为pip）
2）把这部分：
from pip import main
if __name__ == '__main__':
sys.exit(main())
3）改成下面的样子：
from pip import __main__
if __name__ == '__main__':
sys.exit(__main__._main())
4.遇到了：
RROR: THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE. If you have updated the package versions, please update the hashes. Otherwise, examine the package contents carefully; someone may have tampered with them.
解决方法：
这是由于网络问题导致的下载时给的md5校验码跟下载的不完成文件md5码对不上了。
这个没啥好方法，找个网络好点的地方，换个pip3临时国内源，多下几次就好了。
问题三：
输入import tensorflow as tf后出现：
/usr/local/lib/python3.5/dist-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_qint32 = np.dtype([(“qint32”, np.int32, 1)])
/usr/local/lib/python3.5/dist-packages/tensorflow/python/framework/dtypes.py:525: 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’.等等
原因：
我装的numpy版本太高了，是numpy-1.17.3，把版本降低到1.15.0就没问题了。
解决方法：
1）先卸载1.17.3的版本：sudo pip3 uninstall numpy
2）再安装1.15.0就可以了：sudo pip3 install numpy==1.15.0
搞了一晚上终于安装完成了：
测试
进入python，按照下面的代码做测试是否安装成功，来个Hello TensorFlow：
import tensorflow as tf #此步遇到问题参考问题三
hello = tf.constant('Hello TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
