Hello 
I am getting the following error when I test my python scripting binaries and when I try and use the Execute Python block, any help would be appreciated.

    • Exception: java.nio.file.InvalidPathException. Hello Zam, does your Python installation pass the test in Settings-> Preferences-> Python scripting? This looks like a path problem. Most problems come from paths or not pointing to a correct Python environment.

    In particular it looks like the path contains a quote symbol (") which seems to be the problem?  I would try without them...

    @IngoRM There is no (") in the path i double checked it, and tried Python 3.7, 3.6, 3.5.
    all of them not working for the Python Scripting Block

    @varunm1 i double checked the path name, there is no spaces in the name.
    However i created a new Environment in Anaconda Dedicated to RapidMiner with 3.5 Python and its working now.
    Thanks.
