Python 2.7, Redis 3.0.0.post1

sethsec · 2018-11-15T15:11:11Z

Not a celery issue - Seems to be an issue with Redis 3.0.0.post1 installed via pip.

Solution: Roll back redis with pip: pip install redis==2.10.6

everything working again for me.

dannyshaw · 2018-11-16T00:03:24Z

Dependency pinning is a celery issue. Looks to be fixed here though
#5176

guyisra · 2018-11-16T15:16:00Z

Can we quick release 4.2.2 to solve this please?

clokep · 2018-11-16T15:31:20Z

You can pin the dependency outside of Celery until this is fixed.

Latest redis 3.0.1 version is not compatiable with celery, lock the version to 2.10.6 for now. Celery have updated with: celery/celery#5175 not release yet. Signed-off-by: Wayne Sun <gsun@redhat.com>

There was a bug in the latest version of redis package that caused our celery containers to crash. After inspecting the dependencies of all packages, we figured out that redlock hadn't pinned the version of redis due to which the version of redis got upgraded. celery issue for reference celery/celery#5175

greuff · 2018-11-21T17:00:48Z

Pipenv users: add redis = "~=2.10.6" before the celery entry in the Pipfile.

auvipy · 2018-11-22T08:46:35Z

it's fixed in kombu and celery master

new version causes a bug: celery/celery#5175

Can we get a patch release for celery?

thanks

Redis is used as a message broker for Celery. Celery was not pinning properly to Redis and there was an issue with Redis 3.0.0.post1. This pins our secondary Redis dependency to 2.10.6. See celery/celery#5175

This is needed for using with pretalx-docker due to pretalx#534 and celery/celery#5175

wadkar · 2018-12-17T11:10:35Z

Can we get a patch release for celery?

A patch release would be great!!!

Is there something the community can do to make it possible sooner rather than later? As you can see, many related projects are referring to this issue and pinning down the redis version.

thedrow · 2018-12-18T11:48:07Z

I did release a patch for kombu. It should resolve the issue.
Please subscribe for release notifications on our repositories instead of pinging us.

Worked thank you !!

congkhoa · 2019-05-18T05:00:37Z

It should be fixed in newest update: Celery 4.3.0 (kobu 4.5.0).
You don't need to rollback redis version.

True, this works in my case.

Hi,
I am getting issue AttributeError: 'float' object has no attribute 'item'
while executing call back function callbacks = [checkpointer, earlystopper, lr_reducer, TensorBoardColabCallback(tbc)]
which call /usr/local/lib/python3.6/dist-packages/tensorboardcolab/callbacks.py
I have install install redis==2.10.6 still issue persist.
I am using google colab.

wadkar · 2020-07-21T17:33:42Z

@dhanashri88 - I don't think this is a Celery issue. Your issue report/tracceback is not complete, but it looks like this is a tensorboard issue. Please ask their support channel/mailing list/github issues for help.
