【问题描述】：

我的 Docker 文件是

FROM python:3
ADD myapp.py /
RUN pip3 install tensorflow-gpu
RUN pip3 install numpy
RUN pip3 install pandas
CMD ["python3", "./myapp.py]

当我使用构建 docker 映像时 docker build -t gaurav . 我收到以下错误

Step 4/5 : RUN  pip3 install tensorflow-gpu

你能帮我吗，我想安装所有这些包，但我无法克服这些错误。

【问题讨论】：

我尝试改变安装顺序，比如先安装numpy，而不是tensorflow-gpu。我仍然得到同样的错误

【解决方案1】：

https://github.com/tensorflow/tensorflow/issues/33374 - tensorflow 不适用于 python3.8，因此您必须使用 3.7 或更低版本的 python 图像：

FROM python:3.7

【解决方案2】：

如此处所述Tensorflow - requirements。

Tensorflow 仅支持 Python 3.5–3.7
