biosimulators no longer working on macOS

[fbergmann]

Running the bio simulator, just freezes whenever the StandardOutputErrorCapturer is used. When I run without log file, it works, however no output is produced. so

        config = bio_copasi.get_config()
        config.LOG=True
        config.DEBUG=True
        config.VERBOSE=True
        results, log = bio_copasi.exec_sedml_docs_in_combine_archive(
            omexfile, 
            outdir, 
            config=config, 
            fix_copasi_generated_combine_archive=False)

freezes the program, needing for the python process to be killed. while

        config = bio_copasi.get_config()
        config.LOG=False
        config.DEBUG=True
        config.VERBOSE=True
        results, log = bio_copasi.exec_sedml_docs_in_combine_archive(
            omexfile, 
            outdir, 
            config=config, 
            fix_copasi_generated_combine_archive=False)

works fine, however it does not produce any output, and there is a warning message:

StandardOutputNotLoggedWarning: Standard output and error could not be logged because capturer is not installed. To install capturer, install BioSimulators utils with the `logging` option (`pip install biosimulators-utils[logging]`).

it would be nice if output could be produced without needing capturer.

Just curious: what Python version were you using?

[fbergmann]

I have been using python 3.11.3 but it also happens with the default macOS 3.9.6. It is pretty much independent on the python version. I think it is an issue with the capturer library.

[AlexPatrie]

I ask because I have noticed that bio_copasi v. 0.1.25 installs with Python3.11, with the newest bio_copasi version being 0.1.35. When using Python 3.7, the latest version is fetched.

I've created an issue with the utils package, as the problem comes from there. It would still be nice, if the simulator could work even without logging.
