Fail modifying MediaPipe opencv config with setup_opencv.sh

[segobrsm]

Hello! I am currently looking to use Hand Tracking on Desktop from MediaPipe.

So I'm starting to install Mediapipe with the tutorial available in the doc. However I am completely blocked when I install OpenCV by running the setup_opencv.sh file in the command line.

I cloned Mediapipe Git repo in my project folder, then did :

• cd mediapipe
• ./setup_opencv.sh to run the script

The installation goes well until the modification of MediaPipe OpenCV parameters.

The error is as follows:

Modifying MediaPipe opencv config
cd : error retrieving current directory : getcwd : cannot access parent directories : No such file or directory
pwd : error retrieving current directory : getcwd : cannot access parent directories : No such file or directory

I executed the command several times by closing then reopening my terminal. I've done a lot of unsuccessful research. I know that it often comes from when modifying a place file but I did nothing similar, no modification.

Can you help me? I'm really stuck...

OS: Ubuntu 19.10

Not sure what the problem is. But a quick workaround is to manually modify the opencv_build_file and workspace variables in setup_opencv.sh to be the absolute path to those two files.

opencv_build_file=/path/to/your/mediapipe/third_party/opencv_linux.BUILD
workspace_file=/path/to/your/mediapipe//WORKSPACE

Thanks a lot it worked!

This is in the description of the setup_opencv.sh!

To have a full installation:

$ cd

$ sh ./setup_opencv.sh

To only modify the mediapipe config for opencv:

$ cd

$ sh ./setup_opencv.sh config_only

anyone who can help, or know what is going on?
