Hi Dear Lanzani,

Thanks for your help maintaining jetson-docs,

I need to rebuild the mediapipe0.10.7 - python3.8 wheel to run some algorithms using ssh sessions on remote terminals.

Can you share the steps to build the wheel?

Regards
AR

I've implemented a facial detection + recognition code on the Jetson Nano, the facial detection part is implemented using MediaPipe 0.8.5 (BlazeFace model) and runs on the GPU of the Jetson nano, while the recognition is implemented using DLib's face_recognition library and runs on the CPU of the Jetson Nano.

Commenting out the facial recognition part of the code, the facial detection part of the code runs at about 30 fps. But, when I try running both the detection+recognition the overall frame rate drops to about 5 fps. Need help with how I can avoid this drastic drop in the overall frame rate on the Jetson Nano?

After running the command pip3 install v0.8.5/v0.8.5/numpy119x/py36/mediapipe-0.8.5_cuda102-cp36-cp36m-linux_aarch64.whl and waiting for more than 3 hours I got the error below:
~/mediapipe-bin$ pip3 install v0.8.5/v0.8.5/numpy119x/py36/mediapipe-0.8.5_cuda102-cp36-cp36m-linux_aarch64.whl
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip.
Please see pypa/pip#5599 for advice on fixing the underlying issue.
To avoid this problem you can invoke Python with '-m pip' instead of running pip directly.

Please help me resolve this error.

Prior to following the steps on the link: https://jetson-docs.com/libraries/opencv/l4t32.7.1/py3.6.9 I had OpenCV 4.1.2 installed on my system with Cuda support. After implementing all the steps on the same link and after running the command opencv_version I get 4.8.0

But when I run python3 -c "import cv2; print(cv2.__version__)" or Step7 of the link above python3 -c "import cv2; print('OpenCV version:', str(cv2.__version__)); print(cv2.getBuildInformation())" I get OpenCV version: 4.1.2 and it's build details. I need to see OpenCV version as 4.8.0 after running the command python3 -c "import cv2; print('OpenCV version:', str(cv2.__version__)); print(cv2.getBuildInformation())" How do I do this?

Please refer to the image attached in my next comment.

Kindly pls help.

After running every command on the link: https://jetson-docs.com/libraries/opencv/l4t32.7.1/py3.8.0

I'm not able to install openCV 4.8.0

After running the command python3 -c "import cv2; print('OpenCV version:', str(cv2.__version__)); print(cv2.getBuildInformation())" and while trying to import the opencv library I get the following error:

ImportError: OpenCV loader: missing configuration file: ['[config-3.8.py](http://config-3.8.py/)', 'config-3.py']. Check OpenCV installation

Pls note: I've added the line: export PYTHONPATH=/usr/local/lib/python3.6/site-packages:$PYTHONPATH in the bashrc file.

Since I've installed python 3.8, I also tried replacing the abov line with: export PYTHONPATH=/usr/local/lib/python3.8/site-packages:$PYTHONPATH in the bashrc file, but the same Error persists.

How do I resolve this error?
