Hello,

After installing Jupyter-Theme with pip install jupyterthemes, and starting the kernel after the command jt -t chesterish. The Home page at my http://localhost:8888/tree gets to the color of the theme, but nothing is printed, no menus, just a solid colored page, and I'm not able to interact with it anymore.

I've tried:

  1. Reset with jt -r, it gets the empty page white
  2. Uninstall jupyterthemes, reinstall it, and remove it totally
  3. Uninstall and reinstall jupyter & notebook, as well as the remaining folders manually
  4. Clearing my browser cache, as well as privates windows, and different browsers
  5. Uninstalling Python, and replace it in an other PATH

Nothing worked, the Home page remains white after the full Python reinstall.

My configuration:

  1. Windows 10
  2. Python 3.7
  3. All installs are made with pip 19

Wow this sounds terrible (very sorry for the headache).

If you can open up a ipython or python session, what is the output of the following lines

from jupyter_core.paths import jupyter_config_dir, jupyter_data_dir
print('CORE: {}'.format(jupyter_config_dir()))
print('DATA: {}'.format(jupyter_data_dir()))

Are there any files/folders in jupyter_config_dir() ? If so what are they?

Hello @dunovank, Many thanks for the quick reply.

The outputs of the two commands are: CORE: C:\Users\mlabarrere\.jupyter & DATA: C:\Users\mlabarrere\AppData\Roaming\jupyter

Unfortunately, the hidden folder .jupyter does not exist.

Furthermore, the AppData\Roaming\jupyter folder contains one sub folder named runtime, with three files:

  1. nbserver-13504.json
  2. nbserver-13504-open.html
  3. notebook_cookie_secret

The .json is:

{
  "base_url": "/",
  "hostname": "localhost",
  "notebook_dir": "C:\\Users\\mlabarrere",
  "password": false,
  "pid": 13504,
  "port": 8888,
  "secure": false,
  "token": "XX",
  "url": "http://localhost:8888/"
}

And the .HTML one is:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="refresh" content="1;url=http://localhost:8888/tree?token=XX" />
    <title>Opening Jupyter Notebook</title>
</head>
<body>
<p>
    This page should redirect you to Jupyter Notebook. If it doesn't,
    <a href="http://localhost:8888/tree?token=XX">click here to go to Jupyter</a>.
</p>
</body>
</html>

I removed the token ID by XX for clarity

I have the same problem. The outputs of the two commands are:

CORE: C:\Users\ScorpioMiku\.jupyter
DATA: C:\Users\ScorpioMiku\AppData\Roaming\jupyter

Hey guys,

I found out a solution, you need to downgrade the notebook package. To do so:

pip uninstall notebook
pip install notebook==5.7.5

Launch your kernel with the classic jupyter notebook command, normally you'll still see the white page. Do Ctrl+Shift+R to reload without cache, and voilà!

I guess the problem wasn't related to the jupyterthemes package, the notebook one must have been updated in the installation process, but jupyterthemes has nothing to do with the white screen page.

Thanks for your help guys!

Additional note:

If you have kernel issues, don't forget to downgrade the tornado package to the fifth version with:

pip uninstall tornado
pip install tornado==5.1.1
