上面是 html 文件，我正在使用它尝试来自tensorflow js的posenet。
以下是我尝试在谷歌浏览器中打开上述文件时收到的错误。
Uncaught (in promise) DOMException: Failed to execute 'texImage2D' on 'WebGL2RenderingContext': Tainted canvases may not be loaded.

以下是在firefox中打开html文件时出现的错误
'''
SecurityError: The operation is insecure.
Source map error: Error: request failed with status 404

我是初学者，无法理解上述错误。我试图从浏览器中的控制台获取姿势坐标，但我不断收到此错误。
如有任何帮助，我们将不胜感激并提前致谢。

要在本地使用映像，该映像需要由允许 cors 的服务器提供服务。 http-server 可以与命令行一起使用
http-server -c1 --cors .
