Urgent - h2o.init fails pythonw.exe

[Pauw, M, Mej [pauwmarina@sun.ac.za]]

Hello!

 

I have a super urgent question. I have asked a number of people for help by now. Both experienced h2o users (in R) and experienced python scriptwriters. I am really at the end of my rope.

 

When using pyinstaller with python.exe everything works perfectly, however if I add the “-w” command and publish to pythonw.exe it states the machine is actively refusing the connection. This is the full error:

 

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

 

Traceback (most recent call last):

  File "subprocess.py", line 728, in __init__

  File "subprocess.py", line 1025, in _get_handles

OSError: [WinError 6] The handle is invalid

 

I get this error message by setting the stdout to a txt file.

 

I have checked the jar path, the java path and checked that the port is not in use. I have also tried running as administrator.

 

According to pythonw.exe the only difference should be that it does not open a commandline and the output is not printed out to commandline, but to the stdout.

 

I had similar errors wth python.exe, but that was resolved by hardcoding the jar path and running:

h2o.init(strict_version_check=False)

 

I really don’t know what to do anymore as my collaborators are adamant I have to continue to use your package, please, please, please help.

 

Kind regards,

hi,

(note i have never seen anyone try to do this before with the pythonw.  so not sure what to expect.)

what does the output of the java h2o-3 process say?

here you are only showing the output of the python.

also, setting this is bad.  don't do this:

  strict_version_check=False

(what that does is say "ignore client/server version mismatches, and hope the subtle or not-so-subtle errors don't prevent things from working".)
