> Python processor package dependencies are installed into a virtualenv using a
> dependency installer script which is executed from the minifi process using a
> system call. Unfortunately if the virtualenv initialization fails there is no
> indication of the issue in the logs as the script output is only placed on
> the stderr and stdout channels. Failure is only indicated like this:
> {code:java}
> [2025-04-22 12:43:49.150]
> [org::apache::nifi::minifi::core::extension::Module] [error] Failed to
> initialize extension 'PythonExtension' in module
> 'minifi-python-script-extension'
> [2025-04-22 12:43:49.150]
> [org::apache::nifi::minifi::core::extension::ExtensionManager] [error] Failed
> to initialize module 'minifi-python-script-extension' at
> '/home/xavier/Downloads/nifi-minifi-llama-1.0.0/bin/../extensions/libminifi-pyt>
> {code}
> We should add additional logging by capturing the stdout and stderr of the
> installer script and logging it to the minifi application logs for easier
> debugging of the dependency install issues.
