[seyirex]

Hello, i have been trying to load a custom IOT dataset into the IBMFL lib but got this error "No module named ibmfl.util.data_handlers.iot_data_handler" i want to use decision tree as a model but having difficulty bring everything to work, i dont really understand the data handler works, i thing making a tutoral how the data handler works on a custom dataset, this would help new people to understand this lib better. welldone guys am cherring for you guys.

Hi @seyirex , thanks for trying out IBM FL! In case you haven't checked out our tutorials on data handler, I put some related links as follows:

1. Data handler tutorial
2. Video tutorial

From the above log info, it seems like IBM FL can't find this iot_data_handler. Make sure you provide the right path to the file where you define this custom data handler class.
