Python找不到mvnc模块

Question

我一直在尝试设置由英特尔创建的movidius库，但是当我试图导入mvnc包时，我一直被困住了。

要设置mvnc，我遵循以下说明：运动实时目标检测

当需要测试安装是否有效时，我将运行

举例

每当我运行它时，就会产生这个错误。

Traceback (most recent call last):
  File "/usr/local/bin/mvNCCompile", line 25, in <module>
    from Models.Blob import *
  File "/usr/local/bin/ncsdk/Models/Blob.py", line 19, in <module>
    from Controllers.MiscIO import *
  File "/usr/local/bin/ncsdk/Controllers/MiscIO.py", line 35, in <module>
    from mvnc import mvncapi

因此，我想知道如何才能让python识别mvnc模块，以便将它导入到我的任何代码中。谢谢你的帮助!

我正在windows 10计算机上的虚拟机上运行Ubuntu18.04.1LTS

要执行NCSDK的典型安装，请在主机上使用以下命令：

    git clone -b ncsdk2 http://github.com/Movidius/ncsdk && cd ncsdk && make install

您必须启用USB3.0控制器，并为虚拟机创建USB白名单过滤器。

USB3.0特性需要VirtualBox扩展包。

关闭虚拟机

在VirtualBox管理器上选择虚拟机：

Open Settings -> USB
    Check “Enable USB Controller”
    Check “USB 3.0 (xHCI) Controller”
    Add a new USB filter with Vendor ID: 03e7
        The other filter fields can be blank.
    Add a new USB filter with Vendor ID: 040e
        The other filter fields can be blank

在ncsdk目录中使用以下命令下载必要的先决条件和模型并构建所有示例：

make examples
