Problem importing CrazyTokenizer in Colab

[yoonwonj]

There used to be no problems when importing CrazyTokenizer in Colab until February, but now it throws an error of "Protocol not found".

To reproduce errors, Type:

!pip install git+https://github.com/crazyfrogspb/RedditScore.git from redditscore.tokenizer import CrazyTokenizer

Maybe it's because of some updates made? Is there any way to downgrade the version when installing?
