[BUG] "output tensor must have the same type as input tensor" error when i tried to finetune localy

[hichambht32]

Hello everyone, i have 4 gpus RTX 3080 with 10 GiB each and im trying to fine tune mistral 7B v2.0 localy, i tried to optimize as much as i can...(Accelerate with DeepSpeed, 4bit quantization, LoRa and all that stuff) but now i am getting this input and output tensors are not of the same type error
my csv dataset has one column called Text, which includes question-answer pairs
Can you suggest a fix ?
this is the error :
