我有一个使用OpenGL绘制立方体的程序，我想给立方体添加纹理。我正在学习this教程，我的纹理加载代码几乎是从那里复制的。每当我调用load_texture()时，之后的任何OpenGL调用似乎都失败了，没有任何错误被抛出。是否有任何已知的问题可能导致枕头和OpenGL在一起工作时行为异常？我能找到的大多数教程都使用枕头，所以我认为必须有一个变通办法。
下面是我的纹理加载代码：

from OpenGL.GL import *
import gl_debugging as debug
from PIL import Image

# loads a texture from an image file into VRAM

def load_texture(texture_path):
        # open the image file and convert to necessary formats
        print("loading image", texture_path)
        image = Image.open(texture_path)
        convert = image.convert("RGBA")
        image_data = image.transpose(Image.FLIP_TOP_BOTTOM ).tobytes()
        w = image.width
        h = image.height
        image.close()

        # create the texture in VRAM
        texture = glGenTextures(1)
        glBindTexture(GL_TEXTURE_2D, texture)

        # configure some texture settings
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT) # when you try to reference points beyond the edge of the texture, how should it behave?
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT) # in this case, repeat the texture data
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR) # when you zoom in, how should the new pixels be calculated?
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR) # when you zoom out, how should the existing pixels be combined?
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_BASE_LEVEL, 0);
        glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAX_LEVEL, 0);

        # load texture onto the GPU
        glTexImage2D(
                GL_TEXTURE_2D,    # where to load texture data
                0,                # mipmap level
                GL_RGBA8,         # format to store data in
                w,                # image dimensions
                h,                #
                0,                # border thickness
                GL_RGBA,          # format data is provided in
                GL_UNSIGNED_BYTE, # type to read data as
                image_data)       # data to load as texture
        debug.check_gl_error()

        # generate smaller versions of the texture to save time when its zoomed out
        glGenerateMipmap(GL_TEXTURE_2D)

        # clean up afterwards
        glBindTexture(GL_TEXTURE_2D, 0)

        return texture
