Question

我想使用python创建一个openGL项目。下面的代码创建了显示图形的窗口。

import os

import glfw
from OpenGL.GL import *


class renderwindow():
    '''GLFW Renderting window class'''

    def __init__(self):

        #save current working directory
        cwd = os.getcwd()

        #initialize glfw
        glfw.glfwInit()

        #restore cws
        os.chdir(cwd)

        #version hints
        glfw.glfwWindowHint()

        glfw.glfwWindowHint(glfw.GLFW_CONTEXT_VERSION_MAJOR, 3)
        glfw.glfwWindowHint(glfw.GLFW_CONTEXT_VERSION_MINOR, 3)
        glfw.glfwWindowHint(glfw.GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE)
        glfw.glfwWindowHint(glfw.GLFW_OPENGL_PROFILE,
                            glfw.GLFW_OPENGL_CORE_PROFILE)

        # make a window
        self.width, self.height = 640, 480
        self.aspect = self.width / float(self.height)
        self.win = glfw.glfwCreateWindow(self.width, self.height,
                                         b'simpleglfw')

        # make the context current
        glfw.glfwMakeContextCurrent(self.win)

    def main(self):
        glViewport(0, 0, self.width, self.height)
        glEnable(GL_DEPTH_TEST)
        glClearColor(0.5, 0.5, 0.5, 1.0)

运行代码时，它报告如下错误：

Traceback (most recent call last):
  File "/snap/pycharm-community/192/plugins/python-ce/helpers/pydev/pydevd.py", line 1438, in _exec
    pydev_imports.execfile(file, globals, locals)  # execute the script

    rw = renderwindow()

    glfw.glfwInit()
AttributeError: module 'glfw' has no attribute 'glfwInit'

Process finished with exit code 1

我在互联网上搜索解决方案，有人说是由旧版本的GLFW引起的问题。 pycharm与GLFW不匹配。我不知道怎么解决

该方法的名称不是glfwInit，而是init。这也适用于其他方法。（window_hint，create_window，make_context_current）：

import os

import glfw
from OpenGL.GL import *

class renderwindow():
    '''GLFW Renderting window class'''

    def __init__(self):

        #save current working directory
        cwd = os.getcwd()

        #initialize glfw
        glfw.init()

        #restore cws
        os.chdir(cwd)

        #version hints
        glfw.window_hint(glfw.CONTEXT_VERSION_MAJOR, 3)
        glfw.window_hint(glfw.CONTEXT_VERSION_MINOR, 3)
        glfw.window_hint(glfw.OPENGL_FORWARD_COMPAT, GL_TRUE)
        glfw.window_hint(glfw.OPENGL_PROFILE,
                            glfw.OPENGL_CORE_PROFILE)

        # make a window
        self.width, self.height = 640, 480
        self.aspect = self.width / float(self.height)
        self.win = glfw.create_window(self.width, self.height,
                                         'simpleglfw', None, None)

        # make the context current
        glfw.make_context_current(self.win)

    def main(self):
        glViewport(0, 0, self.width, self.height)
        glEnable(GL_DEPTH_TEST)
        glClearColor(0.5, 0.5, 0.5, 1.0)

或者import glfw.GLFW as glfw：

import os

#import glfw
import glfw.GLFW as glfw

from OpenGL.GL import *

class renderwindow():
    '''GLFW Renderting window class'''

    def __init__(self):

        #save current working directory
        cwd = os.getcwd()

        #initialize glfw
        glfw.glfwInit()

        #restore cws
        os.chdir(cwd)

        #version hints
        glfw.glfwWindowHint(glfw.GLFW_CONTEXT_VERSION_MAJOR, 3)
        glfw.glfwWindowHint(glfw.GLFW_CONTEXT_VERSION_MINOR, 3)
        glfw.glfwWindowHint(glfw.GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE)
        glfw.glfwWindowHint(glfw.GLFW_OPENGL_PROFILE,
                            glfw.GLFW_OPENGL_CORE_PROFILE)

        # make a window
        self.width, self.height = 640, 480
        self.aspect = self.width / float(self.height)
        self.win = glfw.glfwCreateWindow(self.width, self.height,
                                         'simpleglfw', None, None)

        # make the context current
        glfw.glfwMakeContextCurrent(self.win)

    def main(self):
        glViewport(0, 0, self.width, self.height)
        glEnable(GL_DEPTH_TEST)
        glClearColor(0.5, 0.5, 0.5, 1.0)

wnd = renderwindow()

如何解决错误：AttributeError：模块'pyglfw'没有属性'pyglfwInit'
