Tabular regression - AttributeError: 'NoneType' object has no attribute 'strip'

[sabatale]

We get the error AttributeError: 'NoneType' object has no attribute 'strip' no matter the input for Tabular regression.

Using the csv sample from the docs yields the same result:

[abhishekkrthakur]

thanks. im taking a look!

[mikeagz]

Same issue on HF Space, but in Classfication tasks

[abhishekkrthakur]

fixed.

@abhishekkrthakur A side question if you don't mind. Is it normal the model type is not recognized properly after being generated with Autotrain?

[abhishekkrthakur]

for tabular, it is an issue. will fix! creating a new issue

I'm still getting this error when running locally. This is the command I'm using: autotrain llm --train --project-name llm-test --model abhishek/llama-2-7b-hf-small-shards --use-peft --trainer sft --data-path . --text-column text --block-size 16 --lr 2e-4 --quantization int4 --gradient-accumulation 4 --mixed-precision none
