Hi,
I'm trying to write a python script that would launch the Jupyter Notebook
server with the additional arguments and had some issues passing the
tornado_settings as an argument to launch_new_instance.
All the other settings are being passed and are set correctly, but when
tornado_setting is passed as an argument, it works on some machines and
doesn't on others.
Here's the code of what I am trying to do:
args += ['--NotebookApp.allow_origin="*"',
'--NotebookApp.disable_check_xsrf=True',
'--NotebookApp.trust_xheaders=True',
'--NotebookApp.open_browser=False',
'--NotebookApp.token=""',
'--NotebookApp.tornado_settings={ \'headers\': {
\'Content-Security-Policy\': \'frame-ancestors \\"self\\" ' + path + '\' }
}']
The error that I am seeing on some machines is the following:
[C 11:51:12.011 NotebookApp] The 'tornado_settings' trait of a NotebookApp
instance must be a dict, but a value of class 'str' (i.e. '{ \'headers\':
{\'Content-Security-Policy\': \'frame-ancestors *\\"self\\*
<https://groups.google.com/>" Some\User\Path\' } }') was specified.
I do understand that it doesn't like the fact that it received a string
instead of a dict, but I don't understand why the same code works only on
some machines and fails on others.
If there's a programmatic way of passing such configurations instead of
modifying the jupyter_notebook_config.py file, it would be ideal as I don't
want to overwrite the config file every time.
Thanks in advance for your help!
Young
