Hi
I was trying to get the examples working at ‘
’. Both examples just throw errors when I copy and try to run them. What should I change to get them working?

Hi Newoptionz
Did you try to add this at the top?

Thanks, I see ‘from AlgorithmImports import *’ is there, the error it is throwing is
‘ def __init__(self in main.py: line 24
name 'dateime' is not defined Stack Trace: During the algorithm initialization, the following exception has occurred: Loader.TryCreatePythonAlgorithm(): Unable to import python module ./cache/algorithm/project/main.pyc. AlgorithmPythonWrapper(): name 'dateime' is not defined
at EarliestExpiringWeeklyAtTheMoneyCallOptionUniverseSelectionModel’
I tried adding ‘import datetime’
Then the error is [ERROR] FATAL UNHANDLED EXCEPTION:Loader.TryCreatePythonAlgorithm(): System.Exception: AlgorithmPythonWrapper(): name 'dateime' is not defined, at EarliestExpiringWeeklyAtTheMoneyCallOptionUniverseSelectionModel, def __init__(self in main.py: line 24, name 'dateime' is not defined, at QuantConnect.AlgorithmFactory.Python.Wrappers.AlgorithmPythonWrapper..ctor(String moduleName) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/AlgorithmFactory/Python/Wrappers/AlgorithmPythonWrapper.cs:line 146, at QuantConnect.AlgorithmFactory.Loader.TryCreate
So looking up ‘datetime’ now.

Note that error message references “dateime“ not ”datetime”, so check if the code contains same typo.

Thanks, good catch.
I tried again and now Example1 works, but example2 still throws the ‘dateime’ error.
Note it is saying
[ERROR] FATAL UNHANDLED EXCEPTION:Loader.TryCreatePythonAlgorithm(): System.Exception: AlgorithmPythonWrapper(): name 'dateime' is not defined, at EarliestExpiringWeeklyAtTheMoneyCallOptionUniverseSelectionModel, def __init__(self in main.py: line 25, name 'dateime' is not defined, at QuantConnect.AlgorithmFactory.Python.Wrappers.AlgorithmPythonWrapper..ctor(String moduleName) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/AlgorithmFactory/
So I think it is seeing ‘dateime’ in ‘EarliestExpiringWeeklyAtTheMoneyCallOptionUniverseSelectionModel’.

Hello All
Sorry that we've made a typo on ‘datetime’. On top of that, we'll also have to include an additional import for the Framework case:
The example algorithms have been updated on the dataset page. Thank you for reporting.
Best
