Custom Python Remove Interpreter with OpenVINO initialization

I use PyCharm to connect to a remote interpreter (but I guess the answer is somewhat unrelated): basically, PyCharm connects to a remote Python interpreter through SSH and execute the code on a remote machine.

The remote interpreter that I used is actually “tweaked”. It is a file called mypython that contains the following code:

#!/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 "$@"

This allows me to specify some environment variables required by Python. Since I install OpenVINO on the remote machine, I would need to add to mypython code the command: source /opt/intel/openvino_2021.1.110/bin/setupvars.sh . However, once I do this, it seems that PyCharm refuses to use my mypython interpreter (it just gets stuck).

Motivation:

• If I ssh into my remote machine and run source /opt/intel/openvino_2021.1.110/bin/setupvars.sh I can then import cv2 correctly from python3
• From the PyCharm remote interpreter instead I get the error:

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

Answer

Possible solution:

• log into the server using ssh
• run source /opt/intel/openvino_2021.1.110/bin/setupvars.sh
• run printenv Include all the variables into the mypython source code. I would still like to know if there is a way to run source /opt/intel/openvino_2021.1.110/bin/setupvars.sh within mypython source code.

EDIT: in my caseremoving this from my environment variables fixed the issue:

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}"

Not sure if I had an old OpenCV version compiled with cuda.
