Windows 命令提示符 ImportError 中的 Python Pandas：无法导入所需的依赖项：numpy (Anaconda)

Question

我正在尝试在 Windows 命令提示符下运行 python 脚本。该脚本在服务器环境中运行，由于我们公司的防火墙，该环境很难安装模块。所以使用 Anaconda 3 很方便，其中包含 python 3.8 和 Pandas 等数据工程模块。

脚本在 Spyder 和 Visual Studio 代码中运行没有问题，但是当我尝试在 Windows 命令行中运行它时，我收到以下错误：

MKL initialization ensuring its correct out-of-the box operation under condition when Gnu OpenMP had already been loaded by Python process is not assured. Please install mkl-service package, see http://github.com/IntelPython/mkl-service
          from . import _distributor_init
        Traceback (most recent call last):

        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:

    Please note and check the following:
    
      * The Python version is: Python3.8 from "C:\ProgramData\Anaconda3\python.exe"
      * The NumPy version is: "1.19.2"

脚本再次在我的 IDE 中运行没有问题，但在 Windows 命令行中没有。请帮忙

尝试升级 pip，如果它们已按以下顺序存在，则尝试卸载。

pip uninstall pandas
pip uninstall numpy
pip install pandas
pip install numpy
