Colab ModuleNotFoundError 'transformers.modeling_albert' when importing

**Describe the compatibility issue **

My code has been working fine for about the past month, but today it seems today something was updated and now I’m getting this error when importing ClassificationModel

To Reproduce

Run these two lines of code in a cell:

!pip install --upgrade transformers
!pip install  simpletransformers

(Should ask you to Restart Runtime, which I do.)

In another cell run: from simpletransformers.classification import ClassificationModel

and you will get the following error:

---------------------------------------------------------------------------

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

Additional Context

Settings for Runtime are: Hardware Accelerator: GPU Memory: High-Ram

Edit: Changed ‘bug’ to ‘compatibility issue’

Same happened to me @pop-ketle .

The Transformers library just updated to 4.0.0 today and introduced some breaking changes. So I tried downgrading to the previous version (3.5.1) and it worked. This is a compatibility issue.

You are correct, and that was a mistake on my part.

Thanks!
