dependency_confusion_test

This code is a high-risk supply-chain pattern: it attempts to install and import potentially typosquatted or nonstandard packages at runtime and then calls an activation function from a third-party module. The snippet swallows errors and lacks integrity checks, creating a clear vector for remote arbitrary code execution if malicious packages exist under those names. Do not run this code. Replace runtime installs with pinned, vetted dependencies, remove dynamic pip installs, audit any such package names, and correct the syntax error in the fragment.
