![]() An example of overpinning is a request for numpy>=1.20.0, which promises that the package will be compatible with any future release of NumPy. Managing Python dependenciesĪny issue involving direct or transitive dependencies can expand into numerous runtime or installation problems, especially considering the bugs in new releases and the overpinning (specifying an overly broad range of versions) that often occur in the Python ecosystem. The resolver algorithm makes sure a version compatible with both Pandas and Tensorflow is installed. ![]() Returning to our example, Pandas 1.3.1 requires numpy>=1.17.3, whereas Tensorflow 2.5.0 requires numpy~=1.19.2. It's up to the resolver algorithm to satisfy all the version ranges and bring all the required dependencies into the environment.Ī new release of a library that's a transitive dependency can influence the whole dependency graph, and thus can bring in new libraries, remove libraries, or adjust the resolved library versions following requirements stated in the release. When installing a package, you can declare a range of acceptable version ranges in library requirements (for instance, numpy>=1.17.3). Because dependencies bring in other dependencies, we call the hidden ones transitive dependencies.Īs of writing this article, the pip installation procedure just shown installs TensorFlow version 2.5.0 and Pandas version 1.3.1. Those packages get updated at unpredictable intervals. The code of Pandas and TensorFlow are not likely to clash, but each of these libraries relies on other libraries that bring desired functionality, such as NumPy, Protobuf, SciPy, and many others. All of these installers resolve packages to the latest versions, which can vary in time from one installation to the next. Instead of pip, we could have installed the libraries using pip-tools, Pipenv, or Poetry. To install these two libraries we issue: $ pip install pandas tensorflow Let’s assume, for simplicity, that we are developing a Python application that calls on two popular libraries: Pandas and TensorFlow. That way, developers can focus on delivering their applications with a lower risk of being confronted with installation-time or runtime issues. The system tries to spot issues in application stacks before application developers see them. Thoth Dependency Monkey was designed to test possible combinations of packages and libraries in Python applications. Note: Also see Thoth prescriptions for resolving Python dependencies: A look at creating and using Thoth prescriptions for healthy Python applications. This article looks at the reasons for Dependency Monkey and how it operates. To make sure applications are shipped in a healthy state, the Thoth team developed Dependency Monkey, which builds and runs Python applications in test environments to uncover issues involving dependencies. Thoth is a recommendation engine for building robust Python software stacks. Fixing such issues can be time-consuming and might require developing domain knowledge about the libraries, which you should be able to treat as black boxes.įor Python programs, a solution is closer at hand thanks to Thoth, a project within the Artificial Intelligence Center of Excellence (AICOE).
