我尝试在 Microsoft Visual Studio 2017 社区中以窗口形式使用 Pythonnet 运行 Visbrain,但我遇到了以下问题。
环境
1) Pythonnet 版本:v2.3.0
我从 Visual Studio 2017 Community 的“Manage Nuget-Package”下载了这个。
2) Python 版本:Python 3.6.5 (Amaconda 3)
环境中已经pip install pythonnet
。
3) 操作系统:Window 7,64 位
4) .net 框架:4.0
===
尝试运行以下代码:
private static void button_Click(object sender, EventArgs e)
{
using (Py.GIL())
{
dynamic myVisbrain = Py.Import("Visbrain");
}
}
调试时
来自 program.cs
Application.Run(new Form1()); // crashes here
错误信息:
Exception thrown: 'System.BadImageFormatException' in System.Windows.Forms.dll

想请教一下,这是什么问题,如何解决。谢谢。
最佳答案
检查您对“Python.Runtime”的引用
它可能指向 32 位版本,而您正在使用 64 位版本
\packages\pythonnet_py27_dotnet.2.3.0\lib\net40\x86\Python.Runtime.dll
改成
\packages\pythonnet_py27_dotnet.2.3.0\lib\net40\x64\Python.Runtime.dll
并且该应用程序应该可以运行。
