Sometimes, you won't be able to use some Python packages within Jupyter Notebook, even after installing the Python packages from Windows command line (cmd), the package may not communicate with Jupyter Notebook
USE the following command in Jupyter Notebook to solve that issue:
! pip install Package_name -- user
For example
! pip install textblob --user
DONT FORGET THE EXLAMATION MARK at beginning, and the -- user at the end.
