Knime batch execute Doesn't Support Python3?

[zzenx]

Using Knime batch execute. has python （1->1） node.
When using python 2 to do execute, is working. but when using python3. always show this:

knime.exe -consoleLog -noexit -reset -nosplash -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir=“E:/Knime/2018/099 MAN Modeling/01 Api analysis and modeling”

CompilerOracle: exclude javax/swing/text/GlyphView.getBreakSpot

what ever I using anaconda, new py 3 install, it is not working.
and it works when I execute it in windows knime
Is there any trick here?

Using windows 10 64bit
Python 3.6.4

I solved this problem.
Need add an -preferences=“E:\Knime\9999 prefrence\python3.epf”
export the preferences file them use the file.

knime.exe -consoleLog -reset -nosplash -nosave -preferences=“E:\Knime\9999 prefrence\python3.epf” -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir=“E:/Knime/03XL/2018/099 MAN Modeling/01 Api analysis and modeling”
