Building and installing mediapipe windows. getting error Permission denied: for opencv_world3410.dll

Question

I am using windows 10 OS for building Mediapipe library locally. Environment setup:

• python3.10
• windows 10 os
• bazel version = 3.7.2
• visual studio 2019

Followed the instructions from this link for building using bazel. with some hick-ups I am able to build the specified hello world from the same above link.

With help of friend I could find building command for hands module.

command1 for building hand_tracking

bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 --action_env PYTHON_BIN_PATH="C://python_310//python.exe" mediapipe/examples/desktop/hand_tracking:hand_tracking_cpu

command 2 for running same.

set GLOG_logtostderr=1

.\bazel-bin\mediapipe\examples\desktop\hand_tracking\hand_tracking_cpu --calculator_graph_config_file=.\mediapipe\graphs\hand_tracking\hand_tracking_desktop_live.pbtxt

This is running just like this link: press run button on top right

I need this as a library installed in my venv. I dont want the readily available pip install mediapipe. as it is not detecting some hand moments correctly. If I build my own on my pc, it is detecting.

I tried this command below,

(mediapipe_venv) C:\dev\mediapipe_repo\mediapipe>python setup.py install

After building and when I run this setup.py install, it is failing as below.

Highlighting error from above.

error: [Errno 13] Permission denied: 'build\lib.win-amd64-3.10\mediapipe\python\opencv_world3410.dll'

Please suggest me if I am following anything wrong.

I am new to building libs locally. and new for BAZEL.

Answer 1

The command line you're using does not have access to 'build\lib.win-amd64-3.10\mediapipe\python\opencv_world3410.dll'

Run the same command in a command line with administrative privileges.
