Cyber RT Python API : An Example¶
This document is an example demonstrating how to use Cyber RT Python API to write your own Python3 programs. Please make sure you have built Apollo successfully.
Step 1: Write your own code.¶
Save it as, say, path/to/my_demo.py.
#!/usr/bin/env python3
import sys
from cyber.python.cyber_py3 import cyber
cyber.init()
if not cyber.ok():
print('Well, something went wrong.')
sys.exit(1)
# Do your job here.
cyber.shutdown()
Step 2: Write Python rule for Bazel to build¶
Edit path/to/BUILD file, add the followng section:
load("@rules_python//python:defs.bzl", "py_binary")
# blablahblah...
# Add your own section here
py_binary(
name = "my_demo",
srcs = ["my_demo.py"],
deps = [
"//cyber/python/cyber_py3:cyber",
],
)
Note: Like C++, Python code is also managed by Bazel starting from Apollo 6.0. Please refer to How to Build and Run Python Apps in Apollo for more on that.
Step 3: Build and run the demo program¶
Now you can run the following commands to build and run the demo program.
bazel build //path/to:my_demo
./bazel-bin/path/to/my_demo
Or simply run
bazel run //path/to:my_demo
