自定义 Python 删除带有 OpenVINO 初始化的解释器

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解释器并执行远程机器上的代码。

我使用的远程解释器实际上是“调整过的”。这是一个名为 mypython 的文件，其中包含以下代码：

#!/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}"

/usr/bin/python3 "$@"

这允许我指定 Python 所需的一些环境变量。由于我在远程机器上安装了 OpenVINO，因此我需要将命令添加到 mypython 代码：source /opt/intel/openvino_2021.1.110/bin/setupvars.sh 。但是，一旦我这样做，PyCharm 似乎拒绝使用我的 mypython 解释器（它只是卡住了）。

动机：

如果我通过 ssh 进入我的远程机器并且运行 source /opt/intel/openvino_2021.1.110/bin/setupvars.sh 然后我可以从 python3
我从 PyCharm 远程解释器得到错误：

Traceback (most recent call last):

Answer 1

可能的解决方案：

使用 ssh 登录服务器
运行 source /opt/intel/openvino_2021.1.110/bin/setupvars.sh
运行 printenv 将所有变量包含到 mypython 源代码中。我仍然想知道在 mypython 源代码中是否有运行 source /opt/intel/openvino_2021.1.110/bin/setupvars.sh 的方法。

编辑：在我的例子中从我的环境变量中删除这个问题解决了这个问题：

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}"

不确定我是否有使用 cuda 编译的旧 OpenCV 版本。
