When I create a new project in pycharm and run the same code, it is solved. — veci Veni, Mar 30 '19 at 06:32
Please check more closely & tag wisely: it is apparent that the error is about `numpy`, not about `machine-learning` of `scikit-learn` (tags edited). — desertnaut, Mar 30 '19 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.) — user2357112, Mar 30 '19 at 10:59
(Also I would strongly recommend using the [`requests`](http://docs.python-requests.org/en/master/) module instead of this `request` thing you have installed.) — user2357112, Mar 30 '19 at 11:03
