Please help me to resolve the above error

### Steps to reproduce the bug

Please resolve the issue of deprecated function np.object to object in the numpy

### Expected behavior

np.object should be written as object only

### Environment info

kaggle notebook

Hi! Kaggle notebooks use an outdated version of `datasets`, so you should update the `datasets` installation (with `!pip install -U datasets`) to avoid the error.

Thank you for your response
