How to contribute¶
Found a bug? Have a new feature to suggest? Want to contribute changes to the codebase? Make sure to read this first.
Bug reporting¶
Your code doesn’t work, and you have determined that the issue lies with Videoflow? Follow these steps to report a bug.
1. Your bug may already be fixed. Make sure to update to the current Videoflow master branch.
2. Search for similar issues. Make sure to delete is:open on the issue search to find solved tickets as well. It’s possible somebody has encountered this bug already. Still having a problem? Open an issue on Github to let us know.
3. Make sure to provide us with useful information about your configuration: What OS are you using? What Tensorflow version are you using? Are you running on GPU? If so, what is your version of Cuda, of CuDNN? What is your GPU?
4. Provide us with a script to reproduce the issue. This script should be runnable as-is and should not require external data download (use randomly generated data if you need to test the flow in some data). We recommend that you use Github Gists to post your code. Any issue that cannot be reproduced is likely to be closed.
If possible, take a shot at fixing the bug yourself –if you can!
The more information you provide, the easier it is for us to validate that there is a bug and the faster we’ll be able to take action. If you want your issue to be resolved quickly, following the steps above is crucial.
Requesting a Feature¶
You can also use Github issues to request features you would like to see in Videoflow, or changes to the Videoflow API.
1. Provide a clear and detailed explanation of the feature you want and why it’s important to add. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you are targeting a minority of users, consider writing and add-on library for Videoflow.
2. Provide code snippets demonstrating the API you have in mind and illustrating the use cases of your feature.
3. After discussing the feature you may choose to attempt a Pull Request. If you are at all able, start writing some code. We always have more work to do than time to do it. If you can write some code then that will speed the process along.
Pull Requests (PRs)¶
Where should I submit my pull request? Videoflow improvements and bug fixes should go to the Videoflow master branch.
Here is a quick guide on how to submit your improvements:
1. Write the code.
2. Make sure any new function or class you introduce has proper docstrings. Make sure any code you touch still has up-to-date docstrings and documentation. Use previously written code as a reference on how to format them. In particular, they should be formatted in MarkDown, and there should be sections for Arguments, Returns and Raises (if applicable).
3. Write tests. Your code should have full unit test coverage. If you want to see your PRs merged promptly, this is crucial.
4. Run our test suite locally. It is easy: from the
Videoflow folder, simply run py.test tests/
5. Make sure all tests are passing.
6. When committing, use appropriate, descriptive commit messages.
7. Update the documentation. If introducing new functionality, make sure you include code snippets demonstrating the usage of your new feature.
8. Submit your PR. If your changes have been approved in a previous discussion, and if you have complete (and passing) unit tests as well as proper doctrings/documentation, your PR is likely to be merged promptly.
