Dear Mohanqwerty5,

Kindly note that you have to use an older version of deepspeech for this model.
pip install deepspeech==0.5.0a5

Ohh thanks, It got solved :)

getting: AttributeError: 'Model' object has no attribute '_impl' and TypeError: init() takes 2 positional arguments but 6 were given on running deepspeech_test_prediction.py
Could you please help me in resolving the mentioned issues.
