A RapidMiner user wants to know the answer to this question: "Hey there. When I try to use phyton execute operator it is giving error saying Failed to detect Python at the given path.

F.e i have 3 cluster and 20 item i wanna that each cluster have 6 item at least or max. 10 item how can i restrict it ? Thank you."

    Hi @Selim,

    Can you check if your python path has " in it. I think the issue might be with " in your path. There shouldn't be " before C:

    Hello @Selim

    Your path looks fine for me. Maybe @Marco_Boeck or @hughesfleming68 can suggest on this?

    If you were using anaconda please create a dedicated environment for rapidminer and install all the necessary packages in this environment, I suggest setting up this new environment with python 3.5 as it work without any issues.

    @lionelderkrikor do you have any suggestions for this.

    @varunm1 May you send me to link ?
    cuz it s forwarding me to  python 3.7 if u sent it i ll be glad . Thanks

    Yep the default is with 3.7. If you want 3.5 you need to create a new environment. The below command can be used in anaconda terminal. Below link will explain to you how to create that.
    conda create -n myenv python = 3.5

    @varunm1,

    I agree with you. Installing Python 3.5 is maybe the solution...

    @varunm1 ; ı want to progress step by step .so firstly am ı gonna use to anaconda navigator to do this instructions ? this web site does not saying where am gonna wrıte this instructions ? ı added my screen of anaconda3 may u check it to discribe me where ı ll write 2 this instructions ?

    You need to use anaconda terminal, type anaconda in your windows search, you can see anaconda prompt. In this prompt, you will run the above-mentioned code which will create a new environment with python 3.5.

    Once you were done creating a new environment, you can close the current anaconda prompt and open prompt for the new environment. For example, if I search for Anaconda on my pc you can see there are two prompts. The first one Anaconda prompt is for default python 3.7 and Anaconda Prompt (Varun) is what I use for rapidminer with 3.5. Similarly, you will get something called myenv. You should open this for installing modules that were required by rapidminer.

     

    you need to install modules like numpy, pandas, etc in the new anaconda prompt (myenv). Before installing check in anaconda navigator in the new environment if you have these packages or not.


    If you want to install pandas, you can search on google "pandas install anaconda" which will show you https://anaconda.org/anaconda/pandas link where you can find a command to install pandas, similarly you need to install numpy etc if they are not available. 

    Hope this helps
