  • Can you update your question with the full traceback? Commented Mar 30, 2019 at 5:56
  • When I create a new project in pycharm and run the same code, it is solved. Commented Mar 30, 2019 at 6:32
  • Please check more closely & tag wisely: it is apparent that the error is about numpy, not about machine-learning of scikit-learn (tags edited). Commented Mar 30, 2019 at 10:52

    The traceback says you named one of your files token.py. The standard library has dibs on the token module name. Using it for your own module breaks the standard library. (It's annoying, but you have to make sure you don't accidentally pick module names the standard library is already using.) Commented Mar 30, 2019 at 10:59

    (Also I would strongly recommend using the requests module instead of this request thing you have installed.) Commented Mar 30, 2019 at 11:03
