珊瑚开发板-无法运行演示

如何解决珊瑚开发板-无法运行演示

我最近购买了一块二手开发板来开始工作。我设法使用启用了Mendel 5（Eagle）的SSH对其进行了刷新，并按照入门说明进行操作，没有任何问题，直到尝试了该演示为止。

我根本无法正常工作！

如果我运行edgetpu_demo --stream

我得到：

shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.
Traceback (most recent call last):

    self._engine = BasicEnginePythonWrapper.CreateFromFile(model_path)

以root身份运行给我：

shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.

(edgetpu_detect_server:7283): Gtk-WARNING **: 02:24:31.914: cannot open display:

哪个看起来更近，但不知道如何解决。我已进行了尽可能多的搜索（为用户添加了plugdev，请确保所有内容均已正确安装）

有什么想法吗？完全确定这是否行得通，有些东西已经坏了。

解决方法

感谢伸出手，这绝对不是一个好兆头。

听起来像董事会一样，如何无法访问Edgetpu，您能给我们发送电子邮件至[e-mail]这个问题吗？
