构建docker镜像时出错

Question

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docker build -t gaurav . 我收到以下错误

Step 4/5 : RUN  pip3 install tensorflow-gpu

你能在这里帮我吗，我想安装所有这些软件包，但我无法克服这些错误。

Answer 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

Answer 2

正如这里所说的 Tensorflow-requirements 。

Tensorflow 仅支持 Python 3.5-3.7
