I am trying to increase the speed of my Python nodes since it seems that there is a bottleneck with getting the data out of the Python node.
I’ve seen in the forums discussions about changing serialization to Apache Arrow. I have version 0.17 installed in my Python3 Anaconda environment (which I have configured in KNIME). After selecting Apache Arrow serialization when I open the Python node I get the following error:
org.knime.python2.kernel.PythonIOException: ‘pyarrow.lib.ChunkedArray’ object has no attribute ‘name’
I’ve seen pyarrow version requirements in old forum posts and am wondering what the current information is on this. Any help is greatly appreciated!
