Mediapipe: Running hello world example after install

[mjcrouse]

OS: Ubuntu 20.04 fresh install
running
export GLOG_logtostderr=1
bazel run --define MEDIAPIPE_DISABLE_GPU=1 mediapipe/examples/desktop/hello_world:hello_world

Originally had the same network error, resolved using JVM solution in #581
Then got a python error (Python 3.8.2 is installed in Ubuntu 20.04), did an apt install of python 2.7 and I'm currently getting this numpy error.

numpy is installed but I think it's attached to my python3 and not 2.7

Solved my problem by running the 3 commands here. (Not sure if just getting numpy may have solved it)

@mjcrouse thank you so much!!!
I have the same problem.
In my case only get numpy may not solved it.
But the problem have been solved after i run the 3 commands in link

[jianshuo]

I actually just did a very little thing and this problem was solved. I run:

export PYTHON_BIN_PATH=/usr/bin/python3

Because the error log mentioned: /root/.cache/bazel/_bazel_root/b5e57353465dda435d68680f86e74fc9/external/bazel_tools/tools/build_defs/repo/http.bzl

and opening this file, it reads:

python_configure depends on the following environment variables:

• PYTHON_BIN_PATH: location of python binary.
• PYTHON_LIB_PATH: Location of python libraries.
  """

So I tried my luck to set one of it and it worked.

[mjcrouse]

Did a fresh install and that also worked for me. Thanks jianshuo

[tonysmarthome]

two commands, then it works
$ export PYTHON_BIN_PATH=/usr/bin/python3
$ sudo apt install python-numpy
