Question

下午好，我想使用pyrender模块从python 3D模型中生成渲染图像。因此，我使用了Code。

--------------------------------------------------------------------------

During handling of the above exception, another exception occurred:

ImportError: ('Unable to load EGL library', 22, 'Le module spécifié est introuvable', None, 126, None, 'EGL', None)

当我运行此代码来生成图像时。我遇到了这个错误：

order by str_to_date(concat('2000-01-01 ', substring_index(str, ' - ', 1)), '%Y-%m-%d %h:%i %p'),
         str_to_date(concat('2000-01-01 ', substring_index(str, ' - ', -1)), '%Y-%m-%d %h:%i %p')

我在python中安装了所有必要的模块，例如pyrender模块，但我不明白问题出在哪里。这里是pyrender工作的链接：link。

Answer 1

您可以尝试

apt-get install libglfw3-dev libgles2-mesa-dev

这解决了我的问题。希望对您有帮助。

Answer 2

就我而言（Ubuntu 18.04，pyrender == 1.43，python == 3.7.8），

sudo apt-get install libosmesa6-dev
sudo apt-get install freeglut3-dev

解决了问题。也许第一行不是必需的。

Answer 3

如果您使用的是 Windows，只需注释掉您指定 PYOPENGL_PLATFORM 的行。

如何修复“ ImportError：无法加载EGL库”，22，版本可解释。
