Notebook: Jupyter notebook blank page on start up

[kennanlau]

Hello All Jupyters mates,

When I launch jupyter, I get a blank page with url: http://localhost:8888/tree

No Dashboard, to listing of current directory.
Just a blank page.
I removed all application & packages below and re-installed again and same blank page.
Tensorflow and python works inside of Windows Terminal, I can perform all functions in terminal but nothing would appear in the web broswer, Chrome, Edge, Firefox.

Any help would be greatly appreciated.

Thanks

Windows 10
I installed the following in order:

1. Miniconda
2. conda create --name tensorflow python=3.6
3. activate tensorflow
4. conda install jupyter
5. jupyter notebook
6. launched Jupyter from icon

Console Output:

pip uninstall notebook
pip install notebook==5.7.5

This seems to be a duplicate of issue #4469.

[kennanlau]

Problem solved by

1. pip uninstall notebook
2. pip install notebook==5.7.5
3. conda create --name tensorflow python=3.6
4. jupyter notebook

Kudos to both alifuk & ciupicri.

Thanks for the quick response.

Instead of a downgrade, you could also try this workaround.

Hi, I am facing same problem.
My notebook is empty http://localhost:8888/tree
Does it mean that I lost all my files and folders?!!!

I did pip uninstall then install notebook but I am still getting the same empty page!
I finally uninstalled then installed Anaconda, but that didn't help either.

Any idea how to get back my notebook?
