树莓派安装TensorFlow遇到的问题

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_quint8 = np.dtype([(“quint8”, np.uint8, 1)])

_np_quint16 = np.dtype([(“quint16”, np.uint16, 1)])

_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))
