Cant Launch Jupyter Notebook

Question

Im still a newbie in anaconda, python and jupyter notebook. I am doing my assignment which is exploring anaconda and jupyter.

windows 10, 64bit
python 3.6.4
anaconda 4.4.10

Why I cant launch jupyter notebook? First time i tried it was successful. And i continue with importing the libraries. Then, when the next time i open anaconda prompt and tried jupyter notebook , i got this error:

Traceback (most recent call last): File "C:\Users\LENOVO\Anaconda3\lib\site-packages\pkg_resources__init__.py", line 2760, in get_entry_map ep_map = self._ep_map File "C:\Users\LENOVO\Anaconda3\lib\site-packages\pkg_resources__init__.py", line 2731, in getattr raise AttributeError(attr) AttributeError: _ep_map

During handling of the above exception, another exception occurred:

Is a big thank you if anyone can help me solve this! :) Feel free to drop any comment/suggestion. Thank you!!

I think the best bet is to uninstall Anaconda and reinstall, but this time, create a conda environment and activate it before you launch jupyter so if this happens again, you can nuke it. — Scratch'N'Purr

First of all i recommend to re install anaconda again and to select the check box which says to Set Anaconda path in system so that you can use it from anywhere.

To make sure that we are going in right direction go to the bin/ in the anaconda folder.

once you are in bin you can see that there is a jupyter-notebook.exe thus execute it in the command prompt.

Also you can try using Anaconda Navigator to do the same thing.

You can also try running it as Administrator if there are any permission issues.

There have been changes in jupyter notebooks latest release so you can read the docs for more info
