很难让googlecoral exampleobjectdetection正常工作

Question

Noob在这里，试图在一个新的GoogleMini开发板上运行GoogleCoral示例对象检测。我已经按照设置设备和加载示例、模型等的所有说明进行了操作。当我尝试运行带有或不带有排序跟踪的detect时，我会得到如下所示的相同错误。似乎问题出在Gstreamer上，但我不知道如何解决。我已经成功地在google coral数据库中使用了其他示例

mendel@green-orange:~/google-coral/example-object-tracker/gstreamer$ python3 detect.py

从Manoj那里得到了一些很好的反馈来运行：“sudo apt get install-y gstreamer1.0-plugins-bad gstreamer1.0-plugins-good python3-gst-1.0 python3 gi gir1.2-gtk-3.0 python3-m pip install svgwrite”

更新错误：

尝试了另一个建议，但仍然没有任何乐趣。还有其他想法吗

更新：我在安装这些软件包时遇到了同样的问题

sudo apt-get install libgstreamer1.0-0 gstreamer1.0-plugins-base gstreamer1.0-plugins-bad gstreamer1.0-tools gstreamer1.0-x
