I need to make my scheduler fire every X days at the specific time (e.g. every 7 days at 11:30)
my code:
def make_interval(record_date: str, record_time: str, record_title: str):
hours, minutes = _get_hours_minutes(record_time)
trigger = AndTrigger([IntervalTrigger(days=int(record_date)),
CronTrigger(hour=hours, minute=minutes)])
scheduler.add_job(_send_notification, trigger=trigger,
kwargs={...},
id=record_title,
timezone=user_timezone)
but I got error: [Errno 22] Invalid argument on the third line.
What's wrong? Can't get why it doesnt work
_get_hours_minutes (just returns separately the value of hours and minutes from "HH:MM")
def _get_hours_minutes(user_time: str) -> (str, str):
return user_time[:2], user_time[3:5]
tracebacks:

I would take a closer look at "record_time" and the format that you pass to "_get_hours_minutes". It has to be in the format of "HH:MM" (assuming that the Errno 22 error is for that line. There are other ways to use the datetime library so that you don't have to slice strings.

Strings passed as data into MistQL's query method correspond to MistQL string types, and thus the #.foo query is attempting to index the string "{\"foo\": \"bar\"}") using the "foo" value, leading to the error above.
MistQL is expecting native dictionaries and lists. The correspondence between Python data types and MistQL data types can be seen here
That being said, the error message is indeed very confusing and should be fixed post-haste! Issue here
The following code throws an exception, which most probably pertains to the TZID replacements I needed to do to fix some other bugs. If I remove the the "UNTIL" statement from the ical string, the code works just fine.

'RRULE UNTIL values must be specified in UTC when DTSTART '
ValueError: RRULE UNTIL values must be specified in UTC when DTSTART is timezone-aware
The solution is to calculate the UNTIL time in UTC and add Z to the end of the time string as described in the RFC:
https://icalendar.org/iCalendar-RFC-5545/3-8-5-3-recurrence-rule.html
the correct RRULE string should look like this:

I am using dask version 0.15.1 and LocalCLuster Client. What could be causing the issue?
We just had a similar error, we were running something of the form:
df[['col1','col2']].groupby('col1').agg("count")
and getting a similar error with this at the end:
return pickle.loads(x)
TypeError: itemgetter expected 1 arguments, got 0
but then when we reformatted the groupby to be of the form:
df.groupby('col1')['col2'].count()
We stopped getting that error. Which we have now repeated a few times and doesn't just seem to be fluke. Not sure at all why that happens, but worth a try if someone is struggling with the same issue.
I have been trying to tweek the mapper_pre_filter example given here. Now, if instead of specifying the command directly in steps, if I'm writing a method to return that command, like this:
from mrjob.job import MRJob
from mrjob.protocol import JSONValueProtocol
class KittiesJob(MRJob):
OUTPUT_PROTOCOL = JSONValueProtocol
def filter_input(self):
return ''' grep 'kitty' '''
def test_for_kitty(self, _, value):
yield None, 0 # make sure we have some output
if 'kitty' in value:
yield None, 1
def sum_missing_kitties(self, _, values):
yield None, sum(values)
def steps(self):
return [
self.mr(mapper_pre_filter=self.filter_input,
mapper=self.test_for_kitty,
reducer=self.sum_missing_kitties)]
if __name__ == '__main__':
KittiesJob().run()
I'm getting the following exception:

Can someone please explain what I'm doing wrong ?
Wow, that's a late answere. I think you want to change this:
mapper_pre_filter=self.filter_input, to
mapper_pre_filter=self.filter_input(),.
From the example mapper_pre_filter is expected to be a string, not a function. Maybe it'll help somebody in the future.
The stack trace says that the output of the filter is not JSON serializable, because it's probably empty.
I've just started using pycassa, so if this is a stupid question, I apologize upfront.

ValueError: Argument for a v1 UUID column name or value was neither a UUID, a datetime, or a number
Any further thoughts?
Thanks,

Turns out that the problem wasn't with the key, it was being caused, in part, by a bug in pycassa that wasn't handling an empty (null) string in the column UUID. A short-term fix is in the answer in google groups:
https://groups.google.com/d/msg/pycassa-discuss/Vf_bSgDIi9M/KTA1kbE9IXAJ
The other part of the answer was to get at the columns by using tuples (with the UUID as a UUID and not a str) instead of a string with ':' separators because that's, as I found out, a cassandra-cli thing.
