File not found error on Windows 10: setup script problem? #1

I cannot get this to work; I get a FileNotFoundError. Here is an example.

PS C:\Users\jcroz\models> python

I installed via pip and the setup script output is

However, the supposedly installed files listed do not exist:

Thanks for the report. Looks like a windows specific issue..
I've updated the helper script, can you try with it?
You need to install the git colomoto_jupyter beforehand:

pip install --user https://github.com/colomoto/colomoto-jupyter/archive/refs/heads/master.zip

and retry stablemotifs_setup (after git pull)

Sorry for the slow reply. I have been doing some testing with Jorge to figure out what's going on with his Java version of stable motifs. I did try this again, and I get a different error now that I am pretty sure this has to do with deprecated Java functions in the stable motifs Java code and not anything with this Python interface. Here is the output:

I strongly suspect this is due to Java dropping Nashorn support in JRE/JDK 15. There is an update in the Java stable motifs readme about this: https://github.com/jgtz/StableMotifs. I've been able to work around this by changing the Python Java calls to point to an older JDK version, i.e.,

java_path = "<path to old Java version>\\bin\\java.exe"
jar_path = "<path to stable motifs Java directory>\\dist\\StableMotifs.jar"

def run_stable_motifs(filepath):
    wd = tempfile.mkdtemp(prefix="StableMotifs-")
    def cleanup():
        shutil.rmtree(wd)
    atexit.register(cleanup)

    shutil.copy(filepath, wd)
    base = os.path.basename(filepath)

    argv = [java_path,'-jar',jar_path, base]
    proc = subprocess.Popen(argv, cwd=wd,stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    result = proc.communicate()
   .
   .
   .

I got this to work with JDK 8 without warnings, but in principle, any version before 15 should work (potentially with lots of warnings about impending deprecation).
