Problem create model if more data and more decimal data

[pelarnut01]

I created data as a csv file to use for create dataset and modeling, but I have a problem when modeling by when using too many csv moles eg using 1000row data Modeling gives error, but if I use 300 rows of data, modeling is no problem.

Traceback (most recent call last): File "/home/pi/.node-red/node_modules/node-red-contrib-machine-learning-v2/nodes/trainers/decision-tree-classifier/../trainer.py", line 20, in

Same problem for me. Seems like the CSV file is not parsed correctly if using to many rows. Have you solved the Problem?
