Python Scripting Error

ZAM

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.

I saw this earlier with @Selim The issue is with spaces in path names. I recommend you install Anaconda with a new environment dedicated to rapidminer that have Python 3.5. This solved a similar error.

• 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.

IngoRM

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.
