popsicle + dawdreamer

[shakfu]

Hi, very cool project, thanks for sharing!! I just mentioned it in the discussions sections of another cool juce + python project. I think these two are complementary and I they work nice together.

I made a somewhat crude demo which is attached.

You will need to pip install dawdreamer and, of course, pip install popsicle

demo.py.zip

[shakfu]

Here's another iteration to address a segfaulting bug with some command line options

[kunitoki]

Sounds great! Thanks for mentioning it. What is the benefit of using dawdreamer over pythonized juce and the c++ capabilities of cppyy?

[shakfu]

Thanks for your reply @kunitoki

What is the benefit of using dawdreamer over pythonized juce and the c++ capabilities of cppyy

I would also add spotify's pedalboard to the same category as dawdreamer: both are pip-installable python packages and both use pybind11 to integrate some subset of JUCE's audio capabilities to enable the creation of audio processing graphs.

I'm sure you can achieve the same with cppyy, but the benefit is that they already exist and already provide novel and differentiated features: midi playback and faust-processing with dawdreamer, and 'strong thread-safety, memory usage, and speed guarantees' with pedalboard.

[kunitoki]

Yeah i understand, they are python packages afterall so they could integrate nicely

[turian]

@shakfu so what does your demo actually do?

[shakfu]

@turian It was some time since I posted it, and I tried to run popsicle examples just now but was getting "uncaught exception in JIT" warnings and execution issues on a Mac m1 machine.

But I think the point I was trying to make is evident from a function calling dawdreamer where a sine wave file is rendered from a daydreamer audio traph which contains a node containing faust code and then displayed on the popsicle sample player.

import dawdreamer as daw
...
def render_sine(path='sine.wav'):
    engine = daw.RenderEngine(SAMPLE_RATE, 512)  # 512 block size
    faust_processor = engine.make_faust_processor("faust")
    faust_processor.set_dsp_string(
        """
        declare name "MySine";
        freq = hslider("freq", 440, 0, 20000, 0);
        gain = hslider("vol[unit:dB]", 0, -120, 20, 0) : ba.db2linear;
        process = freq : os.osc : _*gain <: si.bus(2);
        """
        )
    print(faust_processor.get_parameters_description())
    engine.load_graph([
                       (faust_processor, [])
    ])
    faust_processor.set_parameter("/MySine/freq", 440.)  # 440 Hz
    faust_processor.set_parameter("/MySine/vol", -6.)  # -6 dB volume

    engine.set_bpm(120.)
    engine.render(4., beats=True)  # render 4 beats.
    audio = engine.get_audio()  # shaped (2, N samples)
    wavfile.write(path, SAMPLE_RATE, audio.transpose())
    return path

[kunitoki]

I've started a complete rewrite of popsicle, and i'm currently being addressing audio. The new popsicle should be more stable and break less often as it doesn't rely on cppyy and overall it is manually finetuned.

[shakfu]

Hi @kunitoki that sounds great!

[kunitoki]

I've released the current progress (not really 1.0 but we are approaching it). Feel free to try and report back any feedback !

[shakfu]

@kunitoki I just downloaded it, build it from source and ran the examples (I'm on a M1 MacBook Air).

On the build side: it was very easy and non-problematic to build, your CMakeExtension class is pretty cool, I liked the default universal2 architecture choice and the extension size is a nice 20Mb).

Examples ran great except for drawables.py which crashed on me... I'm not sure was the demo folder contained since it was in cpp.

But overall congrats.. it's looking good. I definitely prefer this pybind11 version of popsicle to the prior one.

[kunitoki]

Nice, glad to hear that!

[kunitoki]

Btw, i saw that you correctly embedded the standard library as a zip file, it would be great to be able to have a step in the demo app that bundles the python std lib so it's standalone. The tricky part is doing it cross platform.

[shakfu]

@kunitoki
Back in the day, I posted about this in stack-overflow.

I have evolved somewhat since then, and now I routinely embed the python standard lib as a zip file in my py-js project and this is one step of of a whole custom build system in python in the builder module.

The specific function in builder looks like the following:

def ziplib(self):
        """zip python package in site-packages to .zip archive"""
        temp_lib_dynload = self.prefix_lib / "lib-dynload"
        temp_os_py = self.prefix_lib / "os.py"

        self.cmd.move(self.site_packages, "/tmp/site-packages")
        self.lib_dynload.rename(temp_lib_dynload)
        self.cmd.copy(self.python_lib / "os.py", temp_os_py)

        zip_path = self.prefix_lib / f"python{self.product.ver_nodot}"
        shutil.make_archive(str(zip_path), "zip", str(self.python_lib))

        self.cmd.remove(self.python_lib)
        self.python_lib.mkdir()
        temp_lib_dynload.rename(self.lib_dynload)
        temp_os_py.rename(self.python_lib / "os.py")
        self.cmd.move("/tmp/site-packages", self.site_packages)

I've only tested this on macOS, but I don't see why this wouldn't work on other platforms.

[kunitoki]

Thanks for the headsup, really appreciated ! Btw i started hacking around a bit:

import os
import sys
import shutil
from pathlib import Path

if __name__ == "__main__":
    base_folder = Path(sys.argv[1])
    output_folder = Path(sys.argv[2])
    version_major = sys.argv[3]
    version_minor = sys.argv[4]

    version = f"{version_major}.{version_minor}"
    version_nodot = f"{version_major}{version_minor}"

    ignored_files = shutil.ignore_patterns(
        "*.pyc",
        "__pycache__",
        "__phello__",
        "*config-3*",
        "*tcl*",
        "*tdbc*",
        "*tk*",
        "Tk*",
        "_tk*",
        "_test*",
        "libpython*",
        "pkgconfig",
        "idlelib",
        "site-packages",
        "test",
        "turtledemo",
    )

    print("cleaning up...")
    shutil.rmtree(str(output_folder / "python"))

    print("copying library...")
    shutil.copytree(
        str(base_folder / "lib" / f"python{version}"),
        str(output_folder / "python"),
        ignore=ignored_files,
        dirs_exist_ok=True)

    print("creating site-packages...")
    os.makedirs(str(output_folder / "python" / "site-packages"), exist_ok=True)

    print("making archive...")
    shutil.make_archive(str(output_folder / f"python{version_nodot}"), "zip", str(output_folder / "python"))

This is executed from cmake and the resulting zip file is embedded in the app, but i've tried bootstrapping python and i cannot find the right way to do it (assuming i setup isolated mode to not look into the system):

libc++abi: terminating due to uncaught exception of type std::runtime_error: failed to get the Python codec of the filesystem encoding

This is the full output of python when it fails initialisation:

  ]

[shakfu]

the stack overflow has a very important note: # NOTE: need os.py to remain in site-packages or it will fail

[kunitoki]

mmmh interesting, but i have no os.py in site-packages in my default python installation ? it is in the standard library default location.

i think the issue is stdlib dir = '/Users/kunitoki/Library/Caches/Popsicle Demo/lib/python3.11' i tried to set the variable to point to the .zip file but it always revert to search in the lib/python3.11 subfolder

[shakfu]

Don't ask me why but, but if you zip the whole of site-packages you need to keep os.py in the root of python311. Look at the screenshot below (note that site-packages is empty because everything is zipped but you still need it there...lib-dynload is empty but doesn't haven't to be (in this case, it is because all extensions are statically linked with libpython + my-code). I've also attached my zipped plugin for your information below the screenshot

py.mxo.zip

[shakfu]

One has to put a single file, os.py, in python3.11 or site-packages ... the key point is that an uncompressed os.py is required for bootstrapping python.

[kunitoki]

yes but i have this like a standard python installation

folder
  \ os.py
  \ ...
  \ site-packages

so should work

[kunitoki]

I couldn't make it work with the zip. The only way i could make it work is by unpacking the zip file in the lib/pythonX.Y folder and pointing the python home the base folder, that works fine.

@kunitoki hope the above script is helpful. It would be useful to know what you will be using the zipped sodlib for..

[kunitoki]

Thanks for sharing, i'm allowing popsicle to work as a JUCE module as well and act as an embeddable python scripting language (with juce exposed thanks to popsicle itself).

You can have a look at the demo app, which is a standalone JUCE app with a bundled python interpreter + python stdlib + popsicle bindings + (optional) custom app bindings.

For now i'm just bundling the python standard library inside the binary itself (the juce way) so it's cross platform https://github.com/kunitoki/popsicle/blob/dev/small_updates/demo/CMakeLists.txt#L42-L55 using this script together with the JUCE's juce_add_binary_data cmake utility.

The application then bootstrap the python home like this https://github.com/kunitoki/popsicle/blob/dev/small_updates/modules/juce_python/scripting/ScriptEngine.cpp#L69-L117 and initializes the python interpreter in isolated mode (so there is no way to mix with user installed pythons).

Cool, I wasn't aware that was possible. After reading this, I was intrigued to see how it worked and I tried to build the demo using:

cd demo
mkdir build
cd build
cmake ..
cmake --build . --config Release

It was building alright but then I got a link error because it was trying and failing to link to my homebrew python

make[2]: *** [popsicle_demo_artefacts/Popsicle Demo.app/Contents/MacOS/Popsicle Demo] Error 1
make[1]: *** [CMakeFiles/popsicle_demo.dir/all] Error 2
make: *** [all] Error 2

I then made the following change to CMakeLists.txt:

# set (Python_ROOT_DIR "/Library/Frameworks/Python.framework/Versions/Current")
set (Python_ROOT_DIR "/opt/homebrew/opt/python@3.11/Frameworks/Python.framework/Versions/Current")

And then it built successfully.

Note that you can get the current homebrew python via brew --prefix python which gives /opt/homebrew/opt/python@3.11 then join it with /Frameworks/Python.framework/Versions/Curren and you have the above. If you want, I can add this via a PR to do this programmatically if homebrew python is found.

I saw that the resultant binary of Popsicle Demo is about 60 MB

Does this include the python standard lib? I searched for juce_add_binary_data but couldn't find an instance that added the python standard library.

[kunitoki]

Yes that thing is in the branch (the opened PR).

As you already discovered you have to change the python root (or comment it). I force that so i can move quickly among versions (i use upstream python so i have universal2 libraries, homebrew usually ship either intel or arm binaries, so i cannot test intel builds on my M1 by launching apps with arch -x86_64), you might also need to tweak or comment https://github.com/kunitoki/popsicle/blob/dev/small_updates/demo/CMakeLists.txt#L79 (depending on which platform you want)

I saw that the resultant binary of Popsicle Demo is about 60 MB

debug or release ? either way, the cmake in master will not strip bnaries (both debug and release) but the one in the branch will strip release builds and include the python library (it's 26mb for ARM only in release).

It was built using cmake --build . --config Release.

Cool. Thanks, will check out the branch version when I can.

I've had a go at building the demo in the dev branch and I had to make a few changes to make it work on my Mac m1 air. I've attached the fixed files with the following caveats: universal arch build didn't work for me for some reason (maybe I need to install Rosetta) and the resulting .app was working ok, but it was not stripped from some reason and was 67.1 MB

The two files which I modified are demo/CMakeLists.txt and popsicle/cmake/ArchivePythonStdlib.py.

Can you check the size of your python3.zip in the build folder ?

[kunitoki]

What is the problem with the python script ? Can you post the error message or the issue ?

The only issue with ArchivePythonStdlib.py was that it failed when it ran because build/python didn't yet exist, so basically this was solved with the following

-    shutil.rmtree(str(final_location))
+    if final_location.exists():
+        shutil.rmtree(final_location)
+    else:
+        final_location.mkdir()

The rest of the changes were trivial like not converting a pathfile.Path to a str() before using it in a shutil.* function since these are already recognized.

@kunitoki congrats on the release which is pretty substantive!

Incidentally, I wanted to ask are python extensions from the sodlib embeddable using juce_add_binary_data?

[kunitoki]

Thanks! It's a small step towards a better integration.

Yes, but you need to unpack them at runtime into a site-packages

[shakfu]

Yes, but the whole pybind11 direction is coming together nicely.

Thanks for the clarification.

@kunitoki

FYI, I just posted an update about the recent popsicle release in the dawdreamer-forum

[kunitoki]

That is nice from you @shakfu thanks a lot ! I was in the process of thinking how i could give this a bit more visibility, and you already did an unexpected great start !!!
