Because it's so useful... ;-)

this notebook is great, and would be even greater if it provides dark theme and vim key bindings!:)

Just a thought. Could be really cool idea to make this super easy in Pineapple.

I'm trying to find a way to add packages to an existing Pineapple installation, after all it comes with pip and all that Jazz in /Applications/Pineapple.app/Contents/Resources/python2.7/bin. So I'd be interested in Bokeh first, but when trying to use the pip bundled in Pineapple I see this weird shebang line: #!/Users/nwhitehead/pineapple/build/python2.7/bin/python which doesn't point to the Python installation bundled with Pineapple... If it would I assume installing some additional stuff might "just work", right?

In fact, I can run in that bin directory above: ./python pip install requests which works (and I think requests wasn't there before, which is slightly surprising). But I'm getting a long number of compilation errors if I try to install bokeh like this.

And I have runned the iPython notebook local.

Are there docs about how to use pineapple?

... and probably all your social profiles.

Open Source Science — It's a thing

But where's the link to repo?

Support other languages such as:

• lua
• haskell
• julia
  etc.

If you output lots of stuff from a cell, and the output needs to be processed by the front-end, you can get in situations where the user interface is not responding for multiple seconds. For example,

def f(x):
return f(x)

This causes a stack overflow with BIG backtrace. Syntax highlighting the backtrace takes a long time, UI is dead until it is processed and displayed.

What should happen: large output is chunked and processed bit by bit, or cut off. Or UI is on different thread, keeps being active while we wait.

Possible workaround: set much smaller stacksize for this specific problem.

Sometimes when you do lots of interrupting and restarting, or if you encounter errors in the app, you can quit the app and end up with python processes still running waiting forever. They should be cleaned up without fail, even in weird cases.

Apparently Pineapple.app/Contents/MacOS/libwx_osx_cocoau-3.1.dylib links against /usr/lib/liblzma.5.dylib which does not exist on 10.8.5.

The application (minimal as well as full version) immediately crashes, showing a window saying "Pineapple cannot be opened because of a problem.". I'm providing details copied from that window below (essentially the same for both versions, minimal and full). For the Python 3.5 version everything is fine.

I've pip installed some special libraries onto my default Python, but there seems to be no way to tell Pineapple to use them? I'd like to be able to configure Pineapple to use a different python interpreter, or failing that, be able to pip install new libraries into Pineapple.

Hi, really impressive project! I have worked on something similar - ipython deskop: https://github.com/mangecoeur/ipython-desktop which I put on hold pending the Jupyter update/split.

I'm really keen to see some kind of desktop frontend emerge for ipython, though I'm personally short on time I'd like to contribute (though I see you went down the native/C route which isn't my strong point :P )

There should be a friendly notebook that opens when you run the app for the first time.

The toolbar in Pineapple is massive and uses a lot of screen realestate and there doesn't seem to be any option to use smaller icons.

It would be nice if this could be reduced in size significantly.

A nice addition would be a version with embedded miniconda distribution. This would open the door to supporting package installs without having all the compilation requirements. You could even just distribute the actual native application, which would prompt you on first open to approve the download, via an option of the miniconda or anaconda install. You then would have less development effort involved with dealing with supporting new versions of python, compilation issues, etc. Just offload all that complexity to anaconda.

You could possibly add a way to export a requirements file as well that would install the requirements to run a notebook.

It looks like the Unix search path inside Pineapple does include its own folder(s) e.g. /Applications/Pineapple-Pro.app//Contents/Resources/python2.7/bin/ so when you install something like Bokeh inside Pineapple (which is now installed by default, but nevertheless) you cannot start installed tools belonging to it like bokeh-server with ! bokeh-server. Having it installed by default doesn't change that.

At the moment ! echo $PATH gives /usr/bin:/bin:/usr/sbin:/sbin only. Adding Pineapple's bin folder should solve this.

I'm not sure if this is possible already but I don't see any documentation about it...

I'm running version 0.5 alpha from the Pineapple-0.5-MacOSX.dmg on Mac OS X 10.10.4 Yosemite. But after a few seconds I'm always getting a yellow triangle with an exclamation mark in it and a message below saying "There appears to be a problem connecting to the local computation server." For a colleague of mine running 10.10.5 it seems to run fine.

Would be great if pineapple could be added to @Homebrew!

https://github.com/Homebrew/homebrew/tree/master/share/doc/homebrew#contributing

This happens with both 2.7 and 3.5 versions.
Theming does not work.
Note that I have a brew-ed Python 2.7 on my system with jupyter installed, but no 3.5 version.

This may be related somehow to issue #15 [https://github.com//issues/15]; I'm not sure. But when I attempted to run Pineapple after installing, a vague error message was displayed about the app possibly being incompatible with OS X 10.10.

Error Message:
Pineapple cannot be opened because of a problem.

"Check with the developer to make sure Pineapple works with this version of OS X. You may need to reinstall the application. Be sure to install any available updates for the application and OS X.

Click Report to see more detailed information and send a report to Apple."

I would appreciate pineapple's supporting Sagemath.

OSX El Capitan
Pineapple-0.8.0 with Python 3.5 (Minimal version)

I have Anaconda distribution installed and use it as the default python installation. However, the "Local Python" option does not start it.

Is it because Pineapple uses python3.5 while Anaconda still uses python3.4?

I am seeing the following Kernel Error when starting Pineapple.

Not sure if it is related (probably?), but some of the features are not functional.
For example: I can not adjust the Theme (nothing happens when clicking on those menu items)

There should be a release that includes lots of libraries all preinstalled and ready to go. Ideas:

• scipy
• pandas
• prettyplotlib
• scikit-image
• scikit-learn
• mayavi
• bokeh
• glumpy
• plotly
• ggplot

It's also nice to have a demo notebook for each package showing the basics of what it's about.

The version with lots of libraries will be big, I'm thinking there should still be a <50MB version to try it out before you waste time downloading the full version.

Currently the program hangs when you try to run the main Pineapple.app from a directory containing a space. This is terrible. At minimum it should show a nice dialog and exit. Better, it should actually work.

The items with more options in the dropdown menu do not seem work. For instance, in the following screenshot, I can use Down Arrow to navigate to "cell type" and then it's kind of "forzen" there. I can't expand more options using Right Arrow or Return. I can't move further down to "Current Output" using Down Arrow, either.

If I use mouse to click "Cell Type", the submenu will pop up and vanish immediately. There's even no time for a screenshot.

I first noticed the behaviour with Pineapple 0.6 and the recent 0.7 doesn't fix it. The issue has been replicated on at least two Mac machines with Yosemite OSX.

import scipy works but not import scipy.signal or from scipy import signal. The error message below occurs. Does this indicate the need for some dependency that isn't contained within the Pineapple installation itself?

Hello - how do I install libraries that do not come built in to Pineapple? I'm using NLTK for an NLP class, but not quite sure how to go about this in Mac OS X.

Pressing Tab yields a dropdown list but it can't be navigated using arrow keys.

There should be example notebooks for topics:

• pineapple package, installing modules, requirements
• ivisual
• working with file data
• scipy examples

The built-in help notebooks were updated to python 3.5, but you can also build for python2.7 so the notebooks are wrong in that case.

This app has the potential to transform my workflow! Amazing! Any chance you could include seaborn in the main distribution? It's what I use everyday.

Make it work on Windows. Totally trivial.

This is amazing, so far! For me it would be wonderful to be able to install psycopg2 as well. When trying to install it in Pineapple-Pro 0.7.4 (Py 2.7) with %pip install psycopg2, I'm getting this

No idea, what's going wrong here. Is there a chance for it to happen?

If a notebook cannot be saved into the file it was loaded from, the UI gets into an inconsistent state since we are waiting to synchronize the state of the notebook. This is bad, it even prevents easy closure of the window (have to wait for timeout dialog).

Ideally this is detected and handled cleanly. If we get into this state, close the window immediately cleanly.

Support python 3.4.

Demo the @ operator.

Found a rather strange error: I don't know enough to submit a fix myself.

When opening Pineapple-Pro from the app list in the GUI, it works perfectly (lovely program btw!).

However, when opening from the terminal with:

open /Applications/Pineapple-Pro.app

it loads, but then when I try to import matplotlib.pyplot there is an import error, whose traceback culminates with:

/Users/rtunnard/Library/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/matplotlib/backends/qt_compat.pyc in ()

ImportError: No module named PySide

Even more strangely, I can import matplotlib by itself, and then matplotlib.pyplot.plot(range(10)) claims that matplotlib has no pyplot attribute!

Not sure if this is a problem caused by my Python setup or a program bug.

Mac OSX 10.10.5 with Enthought Canopy 1.5.0 (Python 2.7.6 64bit).

Jupyter now supports all kinds of kernels which can be installed independently of the Jupyter notebook server itself. These are registered with the kernel by creating kernel definition files in a specific folder: https://ipython.org/ipython-doc/dev/development/kernels.html

It should be possible to configure the Jupyter instance inside pineapple to read these definitions and run the appropriate kernel. This would make it possible to connect to a custom python environment (e.g. you could install Anaconda and use it's ipython kernel) as well as support kernels in other languages (e.g. Julia or R).

When quitting the app from the dock, every time you do "Quit" by rick-clicking it only closes a top-level window. It should close all windows and actually quit, not just do a "Close".

Hi,

Would it be possible to have a GUI only version? What I mean is a distribution that simply uses whatever I already have installed on my system without the need to have (and manage) yet another Python distribution?

Best,

Bruno

Reported by Bill and Peter. Pineapple should "just work" even if the desired ports are already in use by other servers or by other instances of IPython/Jupyter.

Currently when you open the app it will try to open the most recently opened notebook to continue work. Recent files should also be available from a menu item.

Hi. I have a problem with code

import seaborn

It results in
