[tonyc770]

I am trying to run your sample application (Flow), but I get the following Error Message. Can you help?

We solved this error: https://github.com/stavalfi/node-red-machine-learning-project

Look at the notes in the README.md file. No need to look at the source code.

Hi guys,

I tried to run the example (https://flows.nodered.org/node/node-red-contrib-machine-learning). However, bumped into this error. :

Traceback (most recent call last):
  File "/home/administrator/.node-red/node_modules/node-red-contrib-machine-learning/nodes/dataset/create-dataset/create-dataset.py", line 2, in <module>
    import pandas
ImportError: No module named 'pandas'

"Traceback (most recent call last):↵ File "/home/administrator/.node-red/node_modules/node-red-contrib-machine-learning/nodes/assessment/assessment.py", line 1, in ↵ import sklearn.metrics as m↵ImportError: No module named 'sklearn'`

I already install Sci-kit learn and pandas into my /home/administrator drive.

Any help please.

Any help please.

you need Python 3.6.4 or higher accessible by the command 'python' (on linux 'python3') and install the pandas module

Hi, Whenever I was trying to create and train a model with my own dataset the following error occurs from the trainer.What can I do? Any help please.

Recently I have installed all the above components for node-RED on MacOS. My python version is 3.7. When I have imported the test flow form GitHub (https://github.com/GabrieleMaurina/node-red-contrib-machine-learning/tree/master/test) and deployed it, red error icon appeared on left-bottom of all ML nodes, the following displayed as debug messages. Traceback (most recent call last): File "~/.node-red/node_modules/node-red-contrib-machine-learning/nodes/dataset/create-dataset/create-dataset.py", line 2, in import pandas ImportError: No module named pandas

In fact, all the ML related modules are working well with standalone python. $ python Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24) [Clang 6.0 (clang-600.0.57)] on darwin Type "help", "copyright", "credits" or "license" for more information.

import pandas

Is there anybody can advise what's wrong in my node-red/python configuration?
