AttributeError: module '__init__' has no attribute 'read'

[UedaTakeyuki]

An Issue which I can't be reproduced is reported as it would be AttributeError: module '__init__' has no attribute 'read' error. Despite, actually the init.py has read().

I guess the root cause might be that the same name __init__.py unexpected file is found first and imported by the python interpreter.

Would you please check this and report the result? Thank you for your cooperation.

Hi all,
thank you for providing this interesting project.
As HeikoGH I encountered the same issue with pondslider while using same h/w and raspberry OS version:

pi@CO2-raspi:~/mh-z19 $ sudo python -m pondslider --sensor_handlers mh_z19 
Traceback (most recent call last):
  File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.9/runpy.py", line 87, in _run_code
    exec(code, run_globals)
  File "/usr/local/lib/python3.9/dist-packages/pondslider/__main__.py", line 68, in <module>
    pondslider.read(args.config)
AttributeError: module '__init__' has no attribute 'read'
pi@CO2-raspi:~/mh-z19 $

Hopefully someone will find out...
RGDS,
Matthias

Hi Matthias,

It's helpful if I can see which __init__ module is imported.
May I ask you to confirm it as follows?

1. add a line print(pondslider.__file__) on your file /usr/local/lib/python3.9/dist-packages/pondslider/__main__.py under the line of importing __init__ at line #6.

For Example:

import sys
import argparse
import time
import datetime
import __init__ as pondslider

print(pondslider.__file__)

parser = argparse.ArgumentParser()

2. do sudo python -m pondslider and tell me the result.
   In my case, as follow

~/mh-z19 $ sudo python -m pondslider
/usr/local/lib/python2.7/dist-packages/pondslider/__init__.pyc
{'co2': 688}
{"ok":true}

Thank you!

Hi Dr. Takeyuki Ueda,
Apologies for not answering your post! Somehow overlooked it. :-(
Just for checking the status on the faulty installation I made the modification in the main.py as you decribed it above and after doing "sudo python -m pondslider" got this as the result:

pi@CO2-raspi:~/mh-z19 $ sudo python -m pondslider
/home/pi/mh-z19/__init__.py
Traceback (most recent call last):
  File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.9/runpy.py", line 87, in _run_code
    exec(code, run_globals)
  File "/usr/local/lib/python3.9/dist-packages/pondslider/__main__.py", line 69, in <module>
    pondslider.read(args.config)
AttributeError: module '__init__' has no attribute 'read'

Now I am going to update my system with the newest version and will come back with a feedback.

[UedaTakeyuki]

I can reproduce this issue with bullseye, and fix it in the latest version.

[OverTheRhine]

OK, with the reinstalled release from 23/03/2023 the issue seems not to be fixed yet, probably you are working on it?
Many thanks for your efforts!
Matthias

Additional details regarding recent re-installation:
pi@CO2-raspi:~ $ sudo rm ~/mh-z19
then
git clone https://github.com/UedaTakeyuki/mh-z19.git
cd ~/pi/mh-z19
pi@CO2-raspi:~/mh-z19 $ ./setup.sh
=>reboot
pi@CO2-raspi:~/mh-z19 $ sudo python -m mh_z19
This gives plausible values. Next:
pi@CO2-raspi:~/mh-z19 $ sudo python -m pondslider --config config.save.toml
But neither folder /home/pi/DATA nor csv-file were created.

My current CLI workaround:
pi@CO2-raspi:~/mh-z19 $ watch -n 5 sudo python -m mh_z19
:-)

[UedaTakeyuki]

Nice workaround!

By the way, I've added --version option.
Would you mind if I ask again to re-install and confirm python pondslider --version?
Expexted expression is as follows:

pi@raspberrypi:~ $ python -m pondslider --version
version:  0.5.1

[OverTheRhine]

Unfortunately after updating Raspberry Pi OS on my RasPi 3B+ I encountered an error:
E: Archives directory /var/cache/apt/archives/partial is missing. - Acquire (117: Structure needs cleaning)
Usual debugging was not successful, so I decided to set up another RasPi from scratch.
(But for today it's a bit too late. I'll come back soon :-)

[OverTheRhine]

Hello back again!
After complete re-installing the OS, upgrading to lasted OS version I installed mh-z19.git again.
pi@raspberrypi:~/mh-z19 $ python -m pondslider --version version: 0.5.1 {'co2': 620} co2 {"ok":true}
I can confirm this looks like it works now. :-)

I'm very glad to hear this good news!
Thank you for your kind and sympathetic help and patient cooperation. I really appreciate your contribution!

[OverTheRhine]

I really appreciate your effort for fixing this issue in the project.
Despite some exceptions (which I will refer to in another post) after calling
sudo python -m pondslider
I proceeded with setting up the service to connect to your monitor website. And it worked now continuously for 2 days! The very sensitive mh-z19 (as 2000 ppm type) provides plausible data which correlates well to the environment situation.
