title: "How to Fix:TypeError __init() got an unexpected keyword argument 'max_value' relating to Progress Bar
body: <p>I am currently attempting to train a model for speech recognition using mozilla deepspeech. This has been done on linux. Never had an issue with MacOs but having problems now.</p>
  
  <p>I have tired setting up my virtual environment twice to solve this issue but it still is present. As stated above, I have tried this on MacOs but on linux i appear to have an issue. Could it be that python dependencies are installed differently on linux as opposed to mac?</p>

  I expected that the data to train the model would import appropriately but it appears to not do so due to an incompatible progress bar.
