eglInitialize与EGL_NOT_INITIALIZED失败

Question

我正在尝试运行一个3D人类模型生成器，其中使用EGL。当我运行以下代码时：

import OpenGL.EGL as egl
from ctypes import pointer

egl_display = egl.eglGetDisplay(egl.EGL_DEFAULT_DISPLAY)
print(egl_display)

major, minor = egl.EGLint(), egl.EGLint()
print(major, minor)

egl.eglInitialize(egl_display, pointer(major), pointer(minor))

上述代码的输出如下：

#################### the first two print info ####################
<OpenGL._opaque.EGLDisplay_pointer object at 0x7f480e971940>
c_int(0) c_int(0)

#################### error ####################
Traceback (most recent call last):
  File "main.py", line 10, in <module>

  File "src/errorchecker.pyx", line 58, in OpenGL_accelerate.errorchecker._ErrorChecker.glCheckError
OpenGL.raw.EGL._errors.EGLError: EGLError(
        err = EGL_NOT_INITIALIZED,
        baseOperation = eglInitialize,
        cArguments = (
                <OpenGL._opaque.EGLDisplay_pointer object at 0x7f480e971940>,
                <OpenGL.raw.EGL._types.LP_c_int object at 0x7f480e971ac0>,
                <OpenGL.raw.EGL._types.LP_c_int object at 0x7f480e971b40>,
        ),
        result = 0
)

我不熟悉EGL，对这个错误非常困惑，下面是我的机器的信息：

带有CUDA 11.4和驱动程序版本470.82.00的

• 5 NVIDIA GeForce GPU (从安装的libegl1获得，并在/usr/lib/x86_64-linux-gnu/下有以下*.so文件)

/usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0
/usr/lib/x86_64-linux-gnu/libEGL_mesa.so.0.0.0
/usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.0
/usr/lib/x86_64-linux-gnu/libEGL_nvidia.so.470.82.00
/usr/lib/x86_64-linux-gnu/libEGL.so
/usr/lib/x86_64-linux-gnu/libEGL.so.1
/usr/lib/x86_64-linux-gnu/libEGL.so.1.0.0

• 我使用vscode远程ssh运行代码，即我在机器A上工作，而代码实际上运行在机器B上。上面所有的机器信息都是关于机器B的

。

要使eglInitialize正常运行，还需要什么？
