Since before the experiment uses version 1.12 of tensorflow, worried install the new version will not match with the kears version, still choose to install when you install version 1.12. Affected by the new coronavirus, we have been unable to return to school. Home network is not to force, the use pip install tensorflow1.12.0 has been unsuccessful, also tried pip install --upgrade --default-timeout = long time 100 --ignore-installed tensorflow increase this way, but still unsuccessful, finally found a way to use the mirror in temporary Qinghua way
* pip install tensorflow1.12.0 -i https://pypi.tuna.tsinghua.edu.cn/simple*
ultimately successful installation
