在 docker 镜像中安装 Tensorflow 时出错

Question

我正在尝试为我的应用程序在 docker 映像中安装张量流。

我在用于构建映像的文件夹中有 3 个文件。Dockerfile、index.py和requirements.txt

这些文件的内容是

Dockerfile

FROM python:alpine3.7
COPY . /app
WORKDIR /app
RUN pip3 install -r requirements.txt
EXPOSE 5000
CMD python ./index.py

要求.txt

tensorflow==1.1.0
scikit-learn==0.18.2
scipy==0.19.1
numpy==1.13.1
requests==2.18.3

index.py

from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello World!"
if __name__ == "__main__":
app.run(host="0.0.0.0", port=int("5000"), debug=True)

我在命令行中导航到我的 Windows 机器中有这 3 个文件的文件夹，然后执行命令docker build --tag my-python-app2 .

过了一会儿，执行了一会儿后，我收到以下错误消息。

C:UserstestDownloadspython-docker2>docker build --tag my-python-app2 .

The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1

谁能帮忙？

我自己找到了答案。我在Dockerfile中将 tensorflow 的行更改为RUN python3 -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl并将其从需求中删除.txt
