Even though I tried the conll_2003 dataset locally (Which is actually required, to use datasets locally without referring to HF hub). Here is the link to the data that I downloaded and tried. This means to say, if there is something wrong with my custom dataset, it should work with conll_2003. But I got this ERROR when I started with the conell_2003 train.txt , validate.txt from there.
I will be glad to If You help me to get the training done on any dataset, but locally, NOT going to the hub. Thanks
