Hi guys,
I just came across a weird issue with the Keras Network Learner node, within a workflow that works fine on another machine. I guess it has something to do with the python installation or configuration.
Here is the error message
ERROR Keras Network Learner 0:270 Execute failed: org.knime.python2.kernel.PythonOutputListener.setSilenced(Z)V
What’s puzzling is that it seems to be related to python 2, but the python environment for deep-learning
is python 3. I even let KNIME create the environment.
python2 in this case does not refer to Python’s major version 2 but to KNIME’s internal version of the Python integration that is used by the Keras integration under the hood (which is the successor to this old (deprecated) plug-in, hence the 2). In the context of Python, this name is of course a bit unfortunate (but it follows KNIME’s internal naming scheme).
So there is nothing wrong with the (real) Python version you are using. Instead, I believe something must have gone wrong when updating either the KNIME Keras integration or the KNIME Python integration. Could you try to uninstall both and re-install them?
Hi both,
thanks for the quick reply, reinstalling the deep-learning extension and python integration indeed fixed the issue mysteriously
To answer your question @sven-abx the machine where it was initially not working is indeed set up with the mentioned conda and python versions (4.8.3/3.6.10)
