Pyinstaller 3.3.1 & 3.4.0-dev build with apscheduler

Question

Greeting!

I'm trying to make a build using PyInstaller. Config: Python 3.6.5 pip 10.0.1, OS: Ubuntu 18.04. Using virtualenv (also tried with python -m venv).

My app using an apscheduler, websocket, _thread and it seems like some related modules have import problems. Tried pyinstaller --onefile mymain.spec & pyinstaller --onedir mymain.spec. Problem persists in both cases. Program working without errors if not frozen.

here is the error i'm getting if i try to run the generated executable:

Traceback (most recent call last):
  File "apscheduler/schedulers/base.py", line 882, in _create_plugin_instance
KeyError: 'interval'

During handling of the above exception, another exception occurred:

requirements.txt:

jsonpickle==0.9.6
pkg-resources==0.0.0
six==1.11.0
websocket-client==0.48.0
apscheduler==3.5.1
pyinstaller==3.3.1

i need to make a --onefile build.

Note the for example using hiddenimports with these:

missing module named 'wsaccel.xormask' - imported by websocket._abnf
missing module named numpy - imported by websocket._abnf
missing module named win32evtlog - imported by logging.handlers

and any other modules don't help - they still appear in log with missing module flag

Answer 1

Based on Alex Grönholm reply:

The issue was indeed because APScheduler using a setuptools entry points to look up the trigger classes.

Solution is to instantiate trigger and pass to add_job():

from apscheduler.schedulers.background import BackgroundScheduler
from apscheduler.triggers import interval

scheduler = BackgroundScheduler()

trigger = interval.IntervalTrigger(seconds=3)
scheduler.add_job(lambda: job_func(ws), trigger=trigger, id='status_update_job', replace_existing=True)
