            Console.WriteLine("Error");
            Console.WriteLine(str(errors.ToArray()));
            Console.WriteLine();
            Console.WriteLine("Results");
            Console.WriteLine(str(results.ToArray()));
        }
    }
}

调用了anaconda的python3.8 exe，直接运行python脚本。

问题是打包没有实现。

pyinstaller对第三方包，特别是matpoltlib难以实现；nuitka7个小时都没能完成打包。

ironpython对第三方包几乎都无法支持，还是matplotlib。

现在的情况是如果直接使用C#进行科学计算和绘图，则方便打包。
