I completed the requirement configuration according to the instructions of Installing on Debian and Ubuntu
but When running the last command:

$ export GLOG_logtostderr=1
# if you are running on Linux desktop with CPU only
$ bazel run --define MEDIAPIPE_DISABLE_GPU=1 \
    mediapipe/examples/desktop/hello_world:hello_world

Encountered the following error:

Before asking the question, I searched for related issues, but still failed to solve it, so I hope to seek some help :)

The issue is Bazel doesn't find the local python binary. You can run $ which python to find where the python binary is and then add --action_env PYTHON_BIN_PATH=<path to python binary> to the Bazel command like the following

bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 --action_env PYTHON_BIN_PATH="/path/to/python" mediapipe/examples/desktop/hello_world

You successfully built bazel-bin/mediapipe/examples/desktop/hello_world/hello_world. Then, you need to run it ;)

Try the following:

$ export GLOG_logtostderr=1
$ bazel-bin/mediapipe/examples/desktop/hello_world/hello_world
