I'm trying to run the test in lab1 using the following command in Google Colab but it gives me the issue below:

`pytest -s text_recognizer/tests/test_character_predictor.py
`

File "<ipython-input-53-454397c8258a>", line 1
    pytest -s text_recognizer/tests/test_character_predictor.py
                            ^
