inline .show() - recommended install procedure to use ipython / jupyter?

[padovani]

Hello,

I currently have a macOS and a Windows 10 setup running abjad. Both use package tools (brew, for macOS, and chocolatey, for Windows) to install python, abjad, and everything else. I have succeeded to use ipython / jupyter (and also Atom's hydrogen package) to run code in both systems. Nonetheless, I'm not getting to have scores showing inline in jupyter notebooks or in Atom's hydrogen.

Is there a recommended way to install Abjad to have this working? The current docs seem to be still based on 3.0.0 and I'm not sure if I am missing something.

Thanks in advance for any tips!

Hi!

Thank you very much!

In windows I got it to work... on macOS (10.13, python 3.8.6, lilypond 2.20.0) I'm having the error below. It seems to be related to the configuration of lilypond (even if it is already in the PATH).

any ideas?

Thank you again!

Hi,

What do …

~$ lilypond --version
GNU LilyPond 2.21.82

… and …

~$ which lilypond
/Applications/LilyPond.app/Contents/Resources/bin/lilypond

… give you at the terminal?

If the shell doesn’t find LilyPond, then add LilyPond to your path.

If the shell finds a stray file called lilypond (that, for example, you have created and put somewhere that your shell finds), then move this file so that your shell finds the legit LilyPond executable somewhere similar to what I’ve pasted in above.

If the shell does find a valid LilyPond executable, what does …

~$ python

>>> import subprocess
>>> command = ["lilypond", "--version"]
>>> proc = subprocess.run(command, stdout=subprocess.PIPE)
>>> proc.stdout.decode().split()[2]
'2.21.82'

… give you?

When I hide LilyPond from my shell to reproduce your problem, I get …

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'lilypond'

… which is different to what you’re seeing.

The error at the bottom of your stacktrace …

OSError: [Errno 8] Exec format error: 'lilypond'

… is new to me. But Googling makes me think three things:

1. your shell is in fact finding a file called lilypond; but
2. that file is either not the real LilyPond executable; or
3. that file isn’t executable by your user name (which I think is the most likely case).

I’m just guessing, though, based on:

Hi!

Just solved here... I had "lilypond" command working from terminal by using lilypond's instruction to create scripts available here: https://lilypond.org/macos-x.html

So, when I've runned "which lilypond", I didn't got the "/Applications/LilyPond.app/Contents/Resources/bin/lilypond" path, but something like "~/bin/lilypond".

To solve it, I've deleted the scripts I had in my "~/bin" dir (as I had, following LilyPond's instructions) and have added the ""/Applications/LilyPond.app/Contents/Resources/bin/" path to my PATH variable in ~/.bash_profile.

Thank you again for the help! :)
