Data passing to Python node still slow

@Experimenter you might want to consider to do a clean Python installation with a KNIME recommended YAML file for Python 3.7 or 3.8:

Most of the environments have:

python-flatbuffers<2.0

You could use the Conda Environment Propagation to make sure your KNIME Python node does use the correct environment.

If you still encounter problems you might want to share the specific environment you use:

Currently integration KNIME and Python involves matching compatible packages (which is always a challenge with Python in general). You might look forward to a deeper integration of Python/Anaconda and KKNIME in the future.
