So I deleted and reinstalled the most up to date version of Anaconda Navigator with Python 3.6 on Windows 10. I launched Jupyter notebook and tried to import
1, numpy,
2, matplotlib
and 3, pandas
It was able to import Numpy and Matplotlib but for Pandas it gave me a very long error message as follows. I also use a Mac computer and it seems no problem with importing pandas using the Jupyter Notebook.
