-----------------------------------------
Summary: Route DML print statements from JVM back to Python
Key: SYSTEMML-1658
URL: https://issues.apache.org/jira/browse/SYSTEMML-1658
Project: SystemML
Issue Type: Improvement
Components: APIs
Reporter: Mike Dusenberry
Currently, a DML print statement results in a System.out.println call in the
JVM. For Python, this output will not be routed back as Python standard out,
and thus it will not be visible in some environments, such as a Jupyter
notebook. In a Python repl, the output will be visible, but only because the
JVM will be printing to the same terminal as the Python process is running
from, and thus the user will see the output. Since a large amount of ML work
is performed within a notebook using Python, we should figure out how to route
this output back to the Python std out.
