neither button nor command working to hide code #29

kmallick2000 · 2017-01-18T16:29:32Z

Thanks for writing the very useful code.
I am using 4.1.36-44 kernel on Leap 42.1. I can get the code to hide within Jupyter, but cannot get the code to hide in the output to html or pdf, either through command prompt or using the buttons. I get the error:

404 : Not Found

You are requesting a page that does not exist!

I tried putting the notebook file in the root directory of Jupyter and that did not help either. I have conda updated, I am using python 2.7 and nbconvert is ver. 4.2.0.
Any help will be appreciated.

Try starting jupyter with jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']"

Edit: fixed typo

kmallick2000 · 2017-01-18T19:03:08Z

I tried

jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']"

and got

[C 12:01:06.138 NotebookApp] Bad config encountered during initialization:
[C 12:01:06.139 NotebookApp] The 'server_extensions' trait of a NotebookApp instance must be a list, but a value of type 'unicode' (i.e. u"[hide_code.hide_code']") was specified.

And now the icons for html and pdf etc have gone missing from the toolbar.

kirbs- · 2017-01-18T19:07:27Z

You have a typo here ...f type 'unicode' (i.e. u"[hide_code.hide_code']") was specified. Make sure the hide_code.hide_code is wrapped in single quotes. It should look like this jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']"

kmallick2000 · 2017-01-18T19:29:42Z

sorry about that.
now that command goes through and it opens jupyer notebook, but I don't see the icons to hide code, export to html and pdf etc.

kmallick2000 · 2017-01-18T19:54:31Z

I tried the same in Windows 10 and I confirm that the export to html or pdf is not hiding the code.
Now if I can get the icons to show up in linux, I can try again there.

kirbs- · 2017-01-18T20:10:20Z

Can you post pip's output when installing hide_code and the first 5-10 lines console lines when jupyter's console?

kmallick2000 · 2017-01-18T23:03:30Z

I ran pip install hide_code again. This is the output:

I don't see the hide_code's server extension getting loaded. You should this in the consoles first few lines.

Would you post the jupyter and notebook versions your using pip list | grep 'jupyter' and pip list | grep 'notebook'. Jupyter notebook release 4.3 about a month ago.

kmallick2000 · 2017-01-19T03:33:52Z

Jupyter is 1.0.0 and notebook is 4.3.1.

kmallick2000 · 2017-01-19T06:44:07Z

I killed all running jupyter kernels and notebook processes. I restarted a jupyter notebook using

jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']"

Here is the output and it seems the hide_code's server extension is getting loaded fine. But I don't see any of the icons for hiding code, export to html or pdf.

Run python -c "import hide_code; print hide_code.setup_info()" You should get the output below if everything installed correctly.

 });

If you don't see any export buttons on the toolbar the Custom JS contents: section may be blank.

kmallick2000 · 2017-01-24T06:15:34Z

Thanks again. Yes, you are right, I ran
python -c "import hide_code; print hide_code.setup_info()"

and Custom JS contents is indeed blank. How come it is missing and how can I get it back?

kirbs- · 2017-01-24T13:17:41Z

Try running python -c "import hide_code.hide_code as hc; hc.install()"

kmallick2000 · 2017-01-24T15:46:39Z

I am sorry, still no luck. Here is the output from running python -c "import hide_code.hide_code as hc; hc.install()"

Starting hide_code.js install...

I checked and Custom.js is showing in the /home/kaushik/.jupyter/custom folder.

kirbs- · 2017-01-24T20:47:39Z

hide_code is installing itself in /home/kaushik/.jupyter/custom, but the installer doesn't see a custom.js file. Do you see this file in /<installation dir>/static/custom/? Where <installation dir> is the same installation directory from python -c "import hide_code; print hide_code.setup_info()"

kmallick2000 · 2017-01-24T22:13:48Z

I am providing the output of python -c "import hide_code; print hide_code.setup_info()" below. And yes I see a custom.js in home/kaushik/anaconda2/lib/python2.7/site-packages/hide_code.

What can I do?

kirbs- · 2017-01-25T01:14:39Z

Basically what's happening is the pip installer isn't installing hide_code into your conda environment. Running python -c "import hide_code as hc; hc.install('/home/kaushik/anaconda2/lib/python2.7/site-packages/notebook/static/custom')" may take care of it.

kmallick2000 · 2017-01-25T01:51:26Z

Thanks! Yes your suggestion now brings back the icons for hide code, export to html and pdf back. But now back to the original problem. Hide code button works. But the export to html and pdf gives Page 404 error. Bummer!

kirbs- · 2017-01-25T14:00:57Z

Did you start juypter using jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']" from inside your conda environment?

kmallick2000 · 2017-01-25T16:08:27Z

OK, I did jupyter notebook --NotebookApp.server_extensions="['hide_code.hide_code']" and I can hide the code fine, but exporting to html generates the html file but the code is visible.

kirbs- · 2017-01-25T17:23:01Z

Did you save the workbook before exporting?

kmallick2000 · 2017-01-25T17:50:07Z

Yes, I did save.

kirbs- · 2017-01-25T19:24:13Z

Would you post the output from Juypter's console when the 404 error happens?

any resolution on this yet?

coljac · 2017-02-21T06:12:08Z

I'm another Anaconda user with the same issues - I followed all the advice here and got the buttons to show up, but no "hide code" selections are being respected with regards to the output.

MikeHigginbottom · 2017-02-23T08:44:02Z

Same issue as coljac. If I hide code via the cell toolbar or via the buttons on the main toolbar and then diff the output html with the html generated when the code was showing there are no differences. The buttons do function as expected on screen though. It seems to be just a problem with the exported data files (html and both pdf forms).

npyoung · 2017-02-24T00:53:05Z

+1 for the "code gone on screen, but not in output" issue. Python 3.5.1, Jupyter 4.2.1. Added
"hide_code.hide_code": true to my jupyter_notebook_config.json to get around the 404 error, but now I get a PDF that's full of code, even though the code disappears in the browser when using the notebook.

kirbs- · 2017-02-24T01:18:27Z

@coljac @MikeHigginbottom @npyoung would you post the version of nbconvert you're using?

kirbs- · 2017-02-24T01:29:47Z

Also, this extension prints some stuff in Jupyter's console during the export process. Do you see any error messages?

kirbs- · 2017-02-24T13:53:11Z

That's helpful. Please check the metadata for your notebook. Select "Edit Metadata" as the cell toolbar, pick a cell with the code hidden, then click on the "Edit Metadata" button. Do you see JSON similar to this:

{
  "deletable": true,
  "collapsed": false,
  "editable": true,
  "hideCode": true
}

MikeHigginbottom · 2017-02-24T15:54:42Z

With the code hidden there is no Edit Metadata button showing. With the code showing the JSON is empty.

npyoung · 2017-02-24T17:25:51Z

It doesn't look like you can see the "Edit Metadata" buttons on hidden cells. Unhidden code cells have

{
  "trusted": true,
  "collapsed": false
}

I also tried hiding the code, saving, and looking at the raw notebook json - no "hideCode" key in the metadata there either.

kirbs- · 2017-02-24T23:04:33Z

Good, making some progress. What version of notebook are you running?

MikeHigginbottom · 2017-02-24T23:09:49Z

jupyter notebook --version gives 4.3.1 for me

kirbs- · 2017-02-25T01:04:30Z

Tested with notebook 4.3.1, and not seeing any issues. Not sure why this is happening. The cell metadata isn't being written for some reason on your setup. Exporting depends on the metadata to render correctly. Are there any error messages in the console?

MikeHigginbottom · 2017-02-25T10:19:49Z

I'm gonna take a stab in the wild dark then and suggest it might be a path issue (it's always a path issue). Can you give us a rough idea of what is supposed to live where? No errors in the console by the way.

kirbs- · 2017-02-25T14:54:23Z

I've got the next version ready on the dev branch. Maybe that will take care of these issues. The dev version uses nbextension installation instead of bootstrapping custom.js and jupyter config files. To install:

pip install git+https://github.com/kirbs-/hide_code.git@dev --upgrade
python -c "import hide_code; hide_code.uninstall_bootstrapped_files()"
jupyter nbextension install --py hide_code
jupyter nbextension enable --py hide_code
jupyter serverextension enable --py hide_code

Note: add --sys-prefix to jupyter nbextension to install into virtualenv or conda environment.

MikeHigginbottom · 2017-02-25T19:12:46Z

Followed those steps (I think step 5 should be serverextension rather than server_extension btw). Metadata and buttons are now present for hidden code as you described earlier. Existing notebooks still don't hide code on export. Not sure if that behaviour is expected or not. New notebooks seem to work fine now though. Consider this closed with thanks from my perspective.

kirbs- · 2017-02-25T19:58:39Z

Thanks, fixed the typo. Still not sure what caused the first issue. Sounds like either hide_code or notebook JS is corrupting/mangling the cell metadata. When upgrading hide_code, Jupyter and its dependencies is also upgraded to the latest version. Hopefully, that cleans up everything. Anyhow, glad this is resolved.

@kmallick2000 @npyoung @coljac do the instructions above fix your issue too?

coljac · 2017-02-25T21:10:38Z

I performed the following steps:

Deleted ~/.jupyter
Created new conda environment
Ran the install instructions as above (with --sys-prefix)
Restarted jupyter

At this point, the toolbar was there, and the edit metadata button persists when I hide the code, with hideCode: true visible when hidden. Positive.

~~Trying to export gives me a 404:~~

~~404 GET /notebooks/aes/test.ipynb/export/html~~

~~I'll edit this if I find the solution - I might have missed something obvious.~~

Everything looks like it's working now.

kmallick2000 · 2017-03-05T03:57:26Z

Sorry, checking in late.
I confirm that the solution proposed by coljac is working! Thanks a lot for fixing it and for the excellent extension.
The export to pdf still shows the 500 : Internal Server Error, but the Export ot pdf by Latex works for me. I am happy.

npyoung · 2017-05-26T18:49:06Z

Confirming (finally) that the fix works for me, using v0.4.0 now.
