Question

This is a sample Sentimental Analysis code for hotel reviews like positive or negative. I use pandas, transformers, datasets, turkish_lm_tuner libraries. Firstly, I think Path name (C:UsersAta Onur Özdemir so ‘Ö’ letter) and ı changed but it is not fixing and output give same error. Secondly, I create init.py in output folder but this way gives same error. And I define path in enviromental variables but same errors is coming again.I search google and stackoverflow but ı can’t find any way, I try many ways but I didn’t. Please help me 🙂 I search google and stackoverflow but I can’t find any way, I try many ways but I’cant.Please help me 🙂
