Hello,  
I am trying to use node red machine learning package (node-red-contrib-machine-learning) on windows 8.1. I could not make it work. I have checked few posts regarding issues running this package on windows. Is the issue solved now or is there any other alternate package i can use for python machine learning.

Do you have all the pre-req's installed?

## Pre requisites

Be sure to have a working installation of [Node-RED](https://nodered.org/).  
Install python and the following libraries:

- [Python](https://www.python.org/) 3.6.4 or higher accessible by the command 'python' (on linux 'python3')
- [Numpy](http://www.numpy.org/)
- [Pandas](https://pandas.pydata.org/)
- [SciKit-Learn](http://scikit-learn.org/)
- [Tensorflow](https://www.tensorflow.org/) (optional: can be skipped)

I'm not a windows man, but this is the first question I would ask along with

1. what version or NR?
2. What vrsion of node.js  
(you can get both from the NR startup log)

From [python - Error in node-red-contrib-machine-learning - Stack Overflow](https://stackoverflow.com/questions/51572745/error-in-node-red-contrib-machine-learning) I'd say no

Call Python from an exec node. `python --version` returns the version. e.g. `Python 2.7.14`
