使用OpenVINO初始化的自定义Python解释器

Question

我使用PyCharm连接到远程解释器(但我猜答案有点不相关)：基本上，PyCharm通过SSH连接到远程Python解释器，并在远程机器上执行代码。

我使用的远程解释器实际上是“微调”的。它是一个名为mypython的文件，包含以下代码：

#!/bin/bash -l
export PATH="/home/ubuntu/.local/bin:/usr/local/cuda-11.1/bin:/home/ubuntu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:${PATH}"
export LD_LIBRARY_PATH="/home/ubuntu/.local/lib:/usr/local/cuda-11.1/lib64:/home/ubuntu/.local/lib:/usr/local/cuda-11.1/lib64:${LD_LIBRARY_PATH}"
export PYTHONPATH="/home/ubuntu/VideoProcessingFramework/install/bin:${PYTHONPATH}"
export PATH="/home/ubuntu/FFmpeg/build_x64_release_shared/bin:${PATH}"
export LD_LIBRARY_PATH="/home/ubuntu/VideoProcessingFramework/install/bin:${LD_LIBRARY_PATH}"
export LD_LIBRARY_PATH="/home/ubuntu/FFmpeg/build_x64_release_shared/lib:${LD_LIBRARY_PATH}"

export PATH="/home/ubuntu/pytorch/build/bin:${PATH}"
export LD_LIBRARY_PATH="/home/ubuntu/pytorch/build/lib:${LD_LIBRARY_PATH}"

# My attempt at having OpenVINO working on PyCharm remote interpreter

/usr/bin/python3 "$@"

这允许我指定Python所需的一些环境变量。由于我在远程计算机上安装了OpenVINO，所以需要在mypython代码中添加命令：source /opt/intel/openvino_2021.1.110/bin/setupvars.sh。然而，一旦我这样做了，PyCharm似乎拒绝使用我的mypython解释器(它只是被卡住了)。

动机：

• ，如果我将ssh导入远程计算机并运行source /opt/intel/openvino_2021.1.110/bin/setupvars.sh，则可以从PyCharm远程解释器中正确地从python3
• 导入cv2：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/IPython/core/interactiveshell.py", line 2882, in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)
  File "<ipython-input-2-c8ec22b3e787>", line 1, in <module>
    import cv2

可能的解决办法：

使用ssh source /opt/intel/openvino_2021.1.110/bin/setupvars.sh

• run
• 登录到服务器，运行
• printenv，将所有变量包含到mypython源代码中。我仍然想知道是否有一种在source /opt/intel/openvino_2021.1.110/bin/setupvars.sh源代码中运行mypython的方法.

编辑:在我的案例中--从我的环境变量中--解决了这个问题：

export LD_LIBRARY_PATH="/home/ubuntu/.local/lib:/usr/local/cuda-11.1/lib64:/home/ubuntu/.local/lib:/usr/local/cuda-11.1/lib64:${LD_LIBRARY_PATH}"

不确定是否有用cuda编译的旧OpenCV版本。
