redis ConnectionRefusedError
Closed this issue · 3 comments
I'm trying sircel to process dropseq data. Everything seems to work except that I get a connection error to redis server, immediately after initialisation is executed. I can reproduce the error within python
>>> import sircel
>>> import redis
>>> sircel.IO_utils.initialize_redis_pipeline(db=0)Traceback (most recent call last):

The exception is not raised if I start redis server before sircel execution
$ redis-server &
I'm now trying a full sircel run with redis in background.
I've circumvented the requirement for redis. Hopefully this will make running the software easier in the future
Hi, I downloaded sircel on Jan 5th 2018 and am having a similar issue. I do not get a connection error, but the program hangs on "assigning reads" unless I proceed by initializing the redis server similar to dawe's (redis-server &). Is it possible that the issue has to do with the redis configuration file? I am using the default settings currently.
Hi we had a user on our HPC cluster deal with the same exact issue as @saralinker .
Any thoughts on how we can run without redis-server?
