@denfromufa Did you install the widget prior usage w/ import fileupload; fileupload.nbinstall()?
I'm relying on install_nbextension to install it. The relevant code is here.

once I reloaded notebook and jupyter localhost server the _upload() does not generate anything. I'm using Yandex.Browser (enhanced Chromium).

here is the output of !pip install -U fileupload which shows that all requirements were satisfied:

@peteut which widget you mean?

from ipython-file-upload.

peteut avatar peteut commented on July 19, 2024

@denfromufa fileupload is a simple python package, the example shows a simple use case. fileupload.nbinstall() needs to be invoked once to get the JS file installed. Is there a better way to get the JS file installed?

den-run-ai avatar den-run-ai commented on July 19, 2024

@peteut I followed your installation steps including fileupload.nbinstall() but still got the issues listed above.

this widget is working great for me, like it did ~ year ago:

https://github.com/ipython/ipywidgets/blob/master/docs/source/examples/File%20Upload%20Widget.ipynb

I think your package fileupload is over-complicating something!

@peteut you might want to add support for the new (jupyter 4.2) method for javascript installation as well as retaining a more universal version (see, e.g. this page on readthedocs)

It seems fairly clear that the issue is whether the javascript is being copied to the correct directory for the server to find it.

@denfromufa do you get any output from fileupload.nbinstall()? Are there any notebook server logs (particularly when running notebook with the --debug flag)?

@jcb91 Thanks for the hint, this is the way to go.

@jcb91 @peteut latest fixes worked great! also had to use "sudo" system python.
