Celery missing 1 required positional argument on python task

I have a celery beat running under my workspace once per minute. My task is very simple:



@task()

def capturar_placas():

    print('Iniciando Captura de Placas do OpenALPR CLOUD')


But each time celery try to execute my task i got the following error:



File "/home/ronaldo.lanhellas/workspace/github/safepark/pythonvenv/lib64/python3.6/site-packages/kombu/transport/django/models.py", line 29, in Message

    queue = models.ForeignKey(Queue, related_name='messages')

celery.beat.SchedulingError: Couldn't apply scheduled task Capturar Placas: __init__() missing 1 required positional argument: 'on_delete'


Looking at "models.py" from kombu lib i noted that don't exists on_delete argument in FK, but Django 2.x require it. How can i solve that ? Update library maybe ?






python django django-celery

  • You can install it (see this answer) and then adapt the code. If you get it working, I'm sure the repository maintainers would like to see a PR from you.

A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

Image
0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

Calculate evaluation metrics using cross_val_predict sklearn

Image
1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
