无法安装旧版本的 tensorflow

Question

如何在 conda vertual 环境中安装旧版本的 Tensorflow？当我尝试这个命令时，我想要 Tensorflow-gpu 1.4：

conda install tensorflow-gpu=1.4

我在附图中看到了消息。

当我尝试conda create -n tf_1_4 python=3.6 tensorflow-gpu=1.4 时，我得到了这个：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

错误消息指出 Python 必须是 2.7、3.5 或 3.6，而当前环境是 3.7。创建一个新环境：

conda create -n tf_1_4 python=3.6 tensorflow-gpu=1.4
