python - 如何在以 alpine :3. 7 作为基础镜像的 Docker 中安装 tensorflow-1.2.1？我正在使用 python 3

Question

我正在尝试在我的 Docker 镜像中安装 tensorflow 1.2.1，但它总是失败并显示“未找到分发”。

我附上了一个简单的 Dockerfile，我试图在其中安装 tensorflow。您可以在最后一行 CMD 之前找到它。

失败并出现以下错误:

Step 11/12 : RUN pip3 install tensorflow ---> Running in cfee43b9d1f7 Collecting tensorflow Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow The command '/bin/sh -c pip3 install tensorflow' returned a non-zero code: 1

我自己努力在 Alpine 上安装 Tensorflow，但最终构建了一个适用于 Alpine 3.7 的轮子:https://github.com/better/alpine-tensorflow
