我编写了一个成功构建的 docker 映像文件。

但是，当我使用该图像运行容器时，它会产生以下 numpy 错误并退出。

知道如何纠正这种情况吗？

错误：

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.9 from "/opt/venv/bin/python"
  * The NumPy version is: "1.21.2"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /opt/venv/lib/python3.9/site-packages/numpy/core/_multiarray_umath.cpython-39-x86_64-linux-gnu.so)

【解决方案1】：

您是否在 docker 之外安装了 numpy，并复制了 venv？

如果是这样，则为您的主机编译了 C 扩展（根据错误，它不是 Linux）

您需要将 numpy 安装到容器本身中
