在 docker 镜像中安装 TensorFlow 时出错

Question

我正在尝试在我的应用程序的 docker 映像中安装 tensorflow。

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

requirements.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在 Windows 机器中拥有这 3 个文件的文件夹并执行命令 docker build --tag my-python-app2 .

一段时间后，执行一段时间后，我收到以下错误消息。

C:\Users\test\Downloads\python-docker2>docker build --tag my-python-app2 .

No matching distribution found for tensorflow==1.1.0 (from -r requirements.txt (line 1))
The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1

有人可以帮忙吗？

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 requirements.txt

中删除
