Coral Edge TPU USB 加速器驱动安装失败

Question

我正在尝试安装和测试我的 Coral Edge TPU。我正在按照此处的说明进行操作：https://coral.ai/docs/accelerator/get-started/

第一步是从 coral 网站安装驱动程序，但出现以下错误。我试过运行并且没有管理员，并再次卸载和安装，但我得到了同样的错误。

还有其他人运行关注这个问题吗？我在 Windows 10.

这是珊瑚软件中的错误。根据这个帖子 https://github.com/google-coral/edgetpu/issues/260 他们在最新版本（当时是 2.5.0）中搞砸了一些事情。从一个全新的虚拟环境开始，使用 2.1.0 版本和 Python 3.7 的相应驱动程序（从 2.1.0 开始不支持 3.8、3.9）解决了这个问题。

来自那个线程：

For now, I suggest rolling back to the older driver: https://dl.google.com/coral/edgetpu_api/edgetpu_runtime_20200728.zip

And you also need to remove your current tflite_runtime and downgrade it to an older version (make sure to change to the right python version):

pip3 install https://dl.google.com/coral/python/tflite_runtime-2.1.0.post1-cp36-cp36m-win_amd64.whl pip3 install https://dl.google.com/coral/python/tflite_runtime-2.1.0.post1-cp37-cp37m-win_amd64.whl Apologies, we are working to get this fixed ASAP

Answer 2

您需要使用高级启动菜单禁用强制驱动程序签名。之后你可以安装它。您可以转到“设置”应用 >> 转到“更新和安全 -> 恢复”页面来执行此操作。单击“高级启动”部分下的“立即重新启动”按钮。

Answer 3

我们最近上传了一个新包，应该可以解决这个问题： https://dl.google.com/coral/edgetpu_api/edgetpu_runtime_20210119.zip
