提问by Victor Ocampo
I have been getting this error: Unable to find any valuable Window provider. With kivy heres the "full" error:
我一直收到此错误：无法找到任何有价值的 Window 提供程序。使用 kivy 这里是“完整”错误：

from kivy.app import App
from kivy.uix.label import Label
class SimpleKivy(App):
def build(self):
return Label(text="Hello World!!!")
if __name__ == "__main__":
SimpleKivy().run()

有人可以解释这个错误吗

You're probably missing some dependencies. From the docs:
您可能缺少一些依赖项。从文档：
Install the dependencies (skip gstreamer (~120MB) if not needed, see Kivy's dependencies):
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew;python -m pip install kivy.deps.gstreamer
安装依赖项（如果不需要，请跳过 gstreamer (~120MB)，参见 Kivy 的依赖项）：
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew;python -m pip install kivy.deps.gstreamer
.....

The solution above did not work for me. Here is what I had to do to solve the problem on my Windows 10 pc with Anaconda Python 3.6 installed:
上面的解决方案对我不起作用。以下是我在安装了 Anaconda Python 3.6 的 Windows 10 电脑上解决问题所必须做的：
- open an Anaconda prompt window as administrator
- pip uninstall kivy
- pip install kivy
- pip install docutils pygments pypiwin32 kivy.deps.sdl2
- pip install kivy.deps.glew
- 以管理员身份打开 Anaconda 提示窗口
- pip 卸载 kivy
- pip 安装 kivy
- pip 安装 docutils pygments pypiwin32 kivy.deps.sdl2
- pip 安装 kivy.deps.glew

Even i have faced same problem.
即使我也遇到过同样的问题。
Now it is working with conda install
现在它正在使用 conda install
conda config --add channels conda-forge
conda install kivy

try to disable the 3D and the 2D video acceleration acceleration in the (>>display>> settings ) of the virtual software (aka vmbox, vmware).
尝试在虚拟软件（又名 vmbox、vmware）的（>>显示>>设置）中禁用 3D 和 2D 视频加速加速。
