2. Copy the link and paste into 'https://nbviewer.jupyter.org/'
3. Then nbviewer shows 404 : Not Found Remote HTTP 404: Chapter 8 - Vector Space and Subspace.ipynb not found among 10 files

Expected behavior Supposed to be opened by nbviewer.

Desktop (please complete the following information):

It seems to be working today: https://nbviewer.jupyter.org/github/WeijieChen-MacroAnalyst/Linear_Algebra_With_Python/blob/master/Chapter%208%20-%20Vector%20Space%20and%20Subspace.ipynb

This is one of a handful of recent reports about a delay between the file appear on GitHub and nbviewer being able to access it.

Thanks , I found that the solution is to add ?flush_cache=true at the end of every url.

How long will the delay be displayed？

Thanks , I found that the solution is to add ?flush_cache=true at the end of every url. It doesn't seem to work well https://nbviewer.jupyter.org/github/coderzc/machine_learning/blob/master/jupyter/tensorflow/tf_Keras_classification_model.ipynb?flush_cache=true

Yes, I do noticed that sometimes it does not work even if with ?flush_cache=true, but when I get back to those links after one or two days, it is usually working.

I have the same issue. I get error 404 when creating new files in github and trying to open them in nbviewer. Github repo is update and using ?flush_cache=true does not work. Trying to access the notebook directly even after a few hours still gives 404.

The way to make it work is to wait a few minutes and to refresh the folder in repo using nbviewer and only then to I can see my notebook.

I think I have mentioned this in one of the other threads mentioning this same issue, but there seems to be an error in the code where ?flush_cache=false is actually the command that flushes the cache, whereas ?flush_cache=true does not. So to anyone else reading this with the same problem, I recommend trying ?flush_cache=false instead.

@tomerav0 What do you mean "refresh the folder in repo using nbviewer." I have a similar issue and flush_cache=true/false on the folder does not work for me.

How do you refresh it?

I had a similar problem after deleting and reloading the same file in the repository. I renamed repository and now nbviewer works correctly.
