Introduction

In the world of machine learning and data science, testing is a crucial aspect of ensuring the quality and reliability of our code. When it comes to testing Python applications that utilize the RAPIDS library, it's essential to run tests with the dev version of RAPIDS to catch errors early in the development cycle. In this article, we'll explore how to run Python tests with the dev version of RAPIDS and discuss the importance of testing with nightly builds.

Why Test with Dev Version of RAPIDS?

RAPIDS is a library that provides GPU-accelerated data processing and machine learning capabilities. As with any library, it's essential to test our code with the latest version of RAPIDS to ensure compatibility and catch any potential issues. However, testing with the latest version can be challenging, especially when it comes to nightly builds. Nightly builds are versions of the library that are built and released on a daily basis, often with new features and bug fixes.

The Importance of Early Error Detection

When we test our code with the dev version of RAPIDS, we can catch errors and issues early in the development cycle. This is crucial because it allows us to fix problems before they become major issues. For example, in the case of the XGBoost library, a recent issue was reported where the library was not compatible with the latest version of RAPIDS. If we had tested our code with the dev version of RAPIDS, we would have caught this issue early and been able to fix it before it became a major problem.

Setting Up a Separate CI Pipeline for Nightly RAPIDS

While it's essential to test our code with the dev version of RAPIDS, it's also important to note that tests with nightly RAPIDS should be hosted in a separate CI pipeline. This is because failures with nightly RAPIDS should not immediately block daily development work. Instead, we want to detect breakages early and fix them before they become major issues.

Benefits of a Separate CI Pipeline

A separate CI pipeline for nightly RAPIDS provides several benefits, including:

Early error detection: By testing our code with nightly RAPIDS, we can catch errors and issues early in the development cycle.
Reduced downtime: By detecting breakages early, we can reduce downtime and ensure that our code is always available.
Improved code quality: By testing our code with nightly RAPIDS, we can ensure that our code is compatible with the latest version of the library.

How to Run Python Tests with Dev Version of RAPIDS

So, how do we run Python tests with the dev version of RAPIDS? Here are the steps:

Step 1: Install RAPIDS

First, we need to install RAPIDS. We can do this using pip:

pip install rapids-dev

Step 2: Install Required Dependencies

Next, we need to install the required dependencies for our Python application. These may include libraries such as NumPy, pandas, and scikit-learn.

Step 3: Write Tests

Now, we need to write tests for our Python application. We can use a testing framework such as unittest or pytest to write our tests.

Step 4: Run Tests with Dev Version of RAPIDS

Finally, we can run our tests with the dev version of RAPIDS. We can do this by using the RAPIDS_DEV environment variable:

RAPIDS_DEV=1 python -m unittest test.py

Conclusion

In conclusion, testing with the dev version of RAPIDS is essential for ensuring the quality and reliability of our code. By running tests with nightly RAPIDS, we can catch errors and issues early in the development cycle and reduce downtime. A separate CI pipeline for nightly RAPIDS provides several benefits, including early error detection, reduced downtime, and improved code quality. By following the steps outlined in this article, we can run Python tests with the dev version of RAPIDS and ensure that our code is always available and reliable.

Future Work

In the future, we plan to explore other ways to improve our testing workflow, including:

Automating testing: We plan to automate our testing workflow using tools such as Jenkins or CircleCI.
Integrating with other libraries: We plan to integrate our testing workflow with other libraries, such as TensorFlow or PyTorch.
Improving code quality: We plan to improve code quality by using tools such as code linters and code formatters.
