TensorFlow problems encountered during installation

Issues encountered in installing tensor flow after the PIP package and Python have been installed:

First, the default is the foreign mirror source, so limited, can cause errors or download speed is very slow. So look for a domestic Python image source (address: http://blog.csdn.net/yywan1314520/article/details/51045660).

Second, the following error occurred in the installation because it was not added to a trusted address.

Could not find a version this satisfies the requirement TensorFlow (from versions:)

No matching distribution found for tensor flow

Here is my step to install the TensorFlow command:

appledemacbook-pro:~ apple$ pip install-i http://pypi.mirrors.ustc.edu.cn/simple/--trusted-host pypi.mirrors.ustc.edu.cn TensorFlow
The introduction of TF package display in the test is correct:

>>> Import TensorFlow as TF

>>> TF. Session ()
