From d22eb90e091200f6a03db0b96e8b9f50477d3340 Mon Sep 17 00:00:00 2001 From: Rob Royce Date: Fri, 30 Aug 2024 15:08:37 -0700 Subject: [PATCH] Add streaming support (#20) * refactor: better error handling and response parsing for ROS2 tools, add blacklist where applicable. * feat(ros2): add ros2 topic echo tool. * chore: bump version to 1.0.4, update CHANGELOG.md * chore: bump langchain versions. * Simplified within_bounds function by removing redundant 'elif' condition. Improved code readability and maintainability. (#13) * Add unit tests and CI. (#14) * feat(tests): add unit tests for most tools and the ROSATools class. * fix: passing a blacklist into any of the tools no longer overrides the blacklist passed into the ROSA constructor. They are concatenated instead. * feat(CI): add ci workflow. * fix: properly filter out blacklisted topics and nodes. * feat(tests): add ros2 tests. * feat(ci): update humble jobs. * feat(ci): finalize initial version of ci. * feat(tests): add stubs for additional test classes. * docs: update README * chore: bump version to 1.0.5 * fix typos (#17) * Add streaming support (#19) * chore: remove verbose logging where it isn't required. * chore: remove unnecessary apt installations. * fix: minor typo * chore: update gitignore * chore: update PR template * Update turtle agent demo to support streaming responses. * feat(streaming): add the ability to stream responses from ROSA. * feat(demo): update demo script, apply formatting. * feat(demo): update demo TUI, fix bounds checking in turtle tools. * feat(demo): clean up Docker demo, add another example of adding tools to the agent. * docs: update README. * docs: update README. * Update README.md * chore: minor formating and linting. * chore: switch setup configuration to use pyproject.toml * feat(demo): properly implement streaming REPL interface. * chore: bump version to 1.0.6 * chore: specify version in CHANGELOG. --------- Co-authored-by: Kejun Liu <119113065+dawnkisser@users.noreply.github.com> Co-authored-by: Kejun Liu --- .github/PULL_REQUEST_TEMPLATE.md | 5 +- .github/workflows/publish.yml | 4 +- .gitignore | 5 +- CHANGELOG.md | 25 ++ Dockerfile | 65 ++-- demo.sh | 88 +++--- pyproject.toml | 47 +++ setup.py | 54 +--- src/rosa/prompts.py | 6 + src/rosa/rosa.py | 202 ++++++++++--- src/rosa/tools/log.py | 4 +- src/rosa/tools/ros1.py | 24 -- src/rosa/tools/system.py | 2 +- .../launch/{agent => agent.launch} | 2 + src/turtle_agent/scripts/__init__.py | 13 + src/turtle_agent/scripts/help.py | 50 +++ src/turtle_agent/scripts/llm.py | 5 +- src/turtle_agent/scripts/prompts.py | 7 +- src/turtle_agent/scripts/tools/turtle.py | 110 +++---- src/turtle_agent/scripts/turtle_agent.py | 285 ++++++++++++++---- tests/rosa/tools/test_system.py | 6 +- 21 files changed, 674 insertions(+), 335 deletions(-) create mode 100644 pyproject.toml rename src/turtle_agent/launch/{agent => agent.launch} (68%) create mode 100644 src/turtle_agent/scripts/help.py diff --git a/.github/PULL_REQUEST_TEMPLATE.md b/.github/PULL_REQUEST_TEMPLATE.md index c9e9e0f..7831666 100644 --- a/.github/PULL_REQUEST_TEMPLATE.md +++ b/.github/PULL_REQUEST_TEMPLATE.md @@ -1,14 +1,17 @@ ## Purpose - Clear, easy-to-understand sentences outlining the purpose of the PR + ## Proposed Changes - [ADD] ... - [CHANGE] ... - [REMOVE] ... - [FIX] ... + ## Issues - Links to relevant issues - Example: issue-XYZ + ## Testing - Provide some proof you've tested your changes - Example: test results available at ... -- Example: tested on operating system ... \ No newline at end of file +- Example: tested on operating system ... diff --git a/.github/workflows/publish.yml b/.github/workflows/publish.yml index b2cacab..f20d312 100644 --- a/.github/workflows/publish.yml +++ b/.github/workflows/publish.yml @@ -16,10 +16,10 @@ jobs: python-version: '>=3.9 <4.0' - name: Install dependencies - run: pip install setuptools wheel twine + run: pip install build twine - name: Build package - run: python setup.py sdist bdist_wheel + run: python -m build - name: Publish package env: diff --git a/.gitignore b/.gitignore index 7da5da5..ba8dece 100644 --- a/.gitignore +++ b/.gitignore @@ -1,5 +1,8 @@ .idea +.vscode src/jpl_rosa.egg-info build/ dist/ -__pycache__/ \ No newline at end of file +__pycache__/ +docs +.DS_Store diff --git a/CHANGELOG.md b/CHANGELOG.md index b0c2b67..940fdb8 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,31 @@ All notable changes to this project will be documented in this file.
