check_characters.py Error from .io import open_remote

[Aşkın Üçüncü]

Hello there. When I run check_characters.py, I get the following error. I am running it on Google Colab.

!python3 /content/DeepSpeech/training/deepspeech_training/util/check_characters.py -csv /content/cv-corpus-6.1-2020-12-11/tr/clips/train.csv -alpha

Traceback (most recent call last):
