HI, as a beginner I try to follow few examples. Looking at this repo " Fine-tuning a model on a text classification task " (here - [https://bit.ly/3mEBqTM](https://bit.ly/3mEBqTM)) I tried to implement the trainer.hyperparameter\_search() method with either “optuna” and “ray [tune]” .

!pip install optuna --\> seems to work fine  
When running the example shown I keep getting:

RuntimeError: At least one of optuna or ray should be installed. To install optuna run `pip install optuna`.To install ray run `pip install ray[tune]`.

I tried installing both but none works… any guidance would be highly appreciated…

thanks, -Ofer

There is some environment problem it seems, since `transformers` didn’t detect you have `optuna` installed. I’d try restarting your kernel since you seem to be in a notebook.

Yap… indeed, simple and worked. Thanks
