ModuleNotFoundError：当我尝试“pot -h”时，没有名为“libs.open_model_zoo”的模块

Question

目前已经安装了pot 1.0（训练后优化）。我可以在命令pip list 的结果列表中看到pot 1.0。但是当我尝试测试pot -h时，我得到了一个错误信息

ModuleNotFoundError: 没有名为“libs.open_model_zoo”的模块

然后我用pip list 检查了列表，里面没有“库”。什么时候应该安装 libs 包，以及如何安装它？顺便说一句，我在笔记本电脑上成功运行了模型优化器和推理引擎。

这里是系统变量“PYTHONPATH”的变量值：

%INTEL_OPENVINO_DIR%\python\python3.7;
%INTEL_OPENVINO_DIR%\deployment_tools\model_optimizer;
%INTEL_OPENVINO_DIR%\deployment_tools\open_model_zoo;

这里是系统变量“OPENVINOPATH”的变量值：

%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\bin\intel64\Release;
%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\bin\intel64\Debug;
%HDDL_INSTALL_DIR%\bin;
%INTEL_OPENVINO_DIR%\opencv\bin;
%INTEL_OPENVINO_DIR%\openvx\bin;
%INTEL_OPENVINO_DIR%\deployment_tools\ngraph\lib;
%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\external\tbb\bin;

%OPENVINO_PATH% 添加到 PATH 变量中。

这是我收到的错误消息：

Answer 1

如果您使用的是 OpenVINO™ 工具包包，则“libs.open_model_zoo”应包含在安装包中。 但是，如果您使用的是开源 OpenVINO，您可以尝试运行以下命令来检查安装：

git 克隆https://github.com/openvinotoolkit/open_model_zoo.git

cmake -E copy_directory ./open_model_zoo/ /deployment_tools/open_model_zoo/

然后，参考Installation POT from PyPI安装POT

Answer 2

模型优化器是一种工具，用于将在流行框架中训练的模型导入、转换和优化为英特尔工具（尤其是推理引擎）可用的格式。推理引擎是运行深度学习模型的引擎。它包含一组库，可轻松将推理集成到您的应用程序中。因此，模型优化器和推理引擎不依赖于“libs.open_model_zoo”。似乎您的安装有问题。 您可以重新安装 OpenVINO 2021.4。然后，参考以下链接尝试重新安装和设置 POT： https://docs.openvinotoolkit.org/2021.4/pot_InstallationGuide.html#install_and_set_up_pot_from_intel_distribution_of_openvino_toolkit_package
