Error with settings.json file

alexandros

I'm trying to revive Pyo on the Bela Gem and I'm now stuck at the following error:

settings.json didn't have "/parameters" entry.

Here's my settings.json file:

{
  "fileName": "render.cpp",
  "CLArgs": {
    "-p": "16",
    "-C": "8",
    "-B": "16",
    "-H": "-6",
    "-N": "1",
    "-G": "1",
    "-M": "0",
    "-D": "0",
    "-A": "0",
    "--pga-gain-left": "10",
    "--pga-gain-right": "10",
    "user": "",

    "-X": "0",
    "audioExpander": "0",
    "-Y": "",
    "-Z": ""
  }
}

The entries are similar to examples that come with the Bela. What's wrong with this one?

Nothing, it's an old one and the format has now changed. There's a migration system in place but it's not triggered at the right moment.
You should simply change one setting in the ide (e.g.: the block size to 32) and that should fix it.

alexandros

giuliomoro I did change that in the project settings from the IDE. Now I'm getting a crash (it's Pyo and Python embedded in C++). I'll start a new discussion on this one. Thanks.

The settings.json file though changed significantly. Now it contains this:

Should I use this as the settings file for Pyo projects? Or should I set the block size in the file I posted in the OP? If so, which entry is it? -B?

giuliomoro

alexandros . Now it contains this:

Expected, it's been upgraded:

alexandros "version": 2,

Use it as it is. The error is unlikely to be due to any of the settings.

Ward

I encountered this error while helping someone with RNBO. Changing block size to something else and then back fixed it.

I think because this example still has an old format settings.json

giuliomoro

Ward I think because this example still has an old format settings.json

yes correct

alexandros

So this is a known bug that just needs a change in the project's block size? Will this be fixed?

giuliomoro

Yes and yes. You can also set the block size back to what it was before. You just need a change to trigger the update of the json file.

Coming back to this thread as I have been trying to replicate the procedure of installing Pyo (which by the way is now being resurrected by a small team with Olivier, Pyo's creator, being part of it), since the necessary steps were not clear to me.

I've ended up building Pyo from source on my Bela Gem stereo and saving the .whl file on my computer. Then I flashed a fresh image in my board's SD card and copied the .whl file from my computer which I then installed with python3 -m pip install. It all works fine with this one detail. If I use the settings.json file found here, it doesn't work. I try to open the project in Bela's IDE and the IDE shows nothing and sort of stalls. Various buttons reacti, but it's not possible to open any other project, unless I refresh the page in my browser.
If I use the extended settings.json in my previous post, the project runs fine. Do you think it's OK to replace the settings.json file here with the extended one and have that used straight away?

If you want to replicate the steps, let me know and I'll direct you to the correct sources and steps. It would be nice to have Pyo again in the Bela, especially now that it has a developer team and it's more like a community project.

giuliomoro

alexandros Do you think it's OK to replace the settings.json file here with the extended one and have that used straight away?

Yes, as I don't have time to fix the IDE right now. Perhaps if you add a CLArgs node to it as below, it will keep working on the old version of the IDE - though I don't know of anyone who's been using pyo recently...

{
    "version": 2,
    "parameters": {
....
     },
    "CLArgs": {
        "user": "",
        "make": "CPPFLAGS=-I/usr/include/python2.7 -I/usr/include/arm-linux-gnueabihf/python2.7 -fno-strict-aliasing -D_FORTIFY_SOURCE=2 -g0 -fstack-protector-strong -Wformat -Werror=format-security -DNDEBUG -fwrapv -O3 -Wall -Wstrict-prototypes;LDFLAGS=-L/usr/lib/python1.7/config-arm-linux-gnueabihf -L/usr/lib;LDLIBS=-lpython2.7 -lpthread -ldl -lutil -lm -Xlinker -export-dynamic -Wl,-O2 -Wl,-Bsymbolic-functions"
    }
}

alexandros

giuliomoro I have this exact CLArgs entry, with minor changes concerning the Python version which is 3.11, and some directories, like /usr/lib/python3.11/config-3.11-aarch64-linux-gnu/ which is what my Bela Gem stereo has. The link in my previous post includes the exact same CLArgs entry (where I think there is a typo in LDFLAGS=-L/usr/lib/python1.7/config-arm-linux-gnueabih as I think it should be python2.7 and not python1.7), but since Bela Gem comes with Python3.11 I changed all these as the directories wouldn't have been correct.

When you say "the old version of the IDE", what do you mean exactly? I flashed the latest image for the Gem stereo found on Bela's website. How can the IDE be in an old version?

giuliomoro

there's "old IDE" that was running on first-generation Bela boards and "new IDE", running on Gem. The old settings.json was for the "old IDE", the one you have is for the "new IDE". Even though we put some infrastructure in place to do migration from the old to the new, it seems to have failed here. What I was suggest is to add the old CLArgs node (with python 2.7) inside the root of the json document, so that it may still work with the old IDE, while it will be ignored by the new IDE, which will instead use the CLArgs that's nested inside other nodes.

alexandros

giuliomoro But if I have the settings.json file for the new IDE I should be good to go, right?

giuliomoro

Sure, I was just suggesting to try and add that in the repo in the effort of providing backwards compatibility for those using your repo with the old version of the board/IDE. However, that shouldn't be a priority because I don't think pyo on Bela has seen much use in the last few years.
