ValueError: num_samples should be a positive integer value, but got num_samples=0

[ArnabSen123]

Hi, I am new to machine learning and has little experience with coding related to this field. I am stuck at this problem for a long time. Can anyone tell me what change should I make to solve this problem. I have provided my parameters and error log below. I am currently working on this for my university thesis. It will be very much helpful if anyone help me in this matter.

The dataset that I used are from kaggle repository which contains a subset of 20bn-jester dataset

!kaggle datasets download -d toxicmender/20bn-jester
and I have unzipped the file before use
