Panda3D和Python错误：IOError无法加载模型文件

Question

我正试图用Python创建一个Panda3D场景，当我试图运行Python代码时，我得到了：

现在你知道错误和我的代码了，但是我该如何修复错误呢？ 我有熊猫.pth在我的Python文件夹中，这样它可以代替Panda3D附带的Python副本，而我的Python副本与Panda3D附带的注册副本版本相同。 有人能帮忙吗？在

Python 2.7.3版 Panda3D版本1.8.1

Answer 1

非常简单；您的代码引用相对位置的模型，例如phase_4/models/modules/gagShop_TT.bam，而这些文件并不存在于它们各自的位置。要么将它试图加载的模型放在正确的位置，要么更正相对路径以指向模型文件的正确位置。在

如果这些模型存在于.mf多文件中（我假设它们是因为它们看起来来自迪斯尼卡通城），那么您必须使用虚拟文件系统挂载多文件（请参阅Panda3D手册），或者使用multify实用程序将它们解压到磁盘上。在
