hyperparameter tuning

[husai033]

Thanks for the "Text-classification/Sentiment Analysis with Hyper Parameter tuning" colab. Could you please provide suggestions to solve the following issue:
I got an error message when I run "best_run = trainer.hyperparameter_search(..." as the following:
OperationalError: unable to open database file

The above exception was the direct cause of the following exception:

OperationalError Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/sqlalchemy/engine/default.py in connect(self, *cargs, **cparams)
506 def connect(self, *cargs, **cparams):
507 # inherits the docstring from interfaces.Dialect.connect
--> 508 return self.dbapi.connect(*cargs, **cparams)

can you check if you have google drive connected because the SQL storage link point to drive ( storage="sqlite:////content/drive/MyDrive/{}.db".format(name),) you can also change it to the local file system

Do you mean drive mount? I already mounted it. Could you please explain how to connect it and how to change it to local file? also, does Optuna applies cross-validation approach during hyperparameter tuning? your help is highly appreciated
