C2W3 Assignment - Great Expectations

Hi,

I need help resetting the assignment for Course 2 Week 3.

I encountered a problem when reaching exercise 6 (see below)


Wasn’t too sure how to fix this, so I tried to restart from the beginning all over again, but this didn’t work out, as some of the variables and mysql database were already created.

Could you please help me with resetting this lab, and also it would be greatly appreciated if you could please point out why I got the errors in exercise 6.

I do suspect that it could be because of the great_expectations.yml configuration file. Do I need to change all the class_name to TupleS3StoreBackend instead of TupleFilesystemStoreBackend, and replace the ‘base_directory’ with ‘prefix’?

Thank you!!

Hello @jp35279024,

If you want to start again you could try deleting config_variables.yml file and great_expectations.yml from the gx folder then run great_expectation init again. That way you will start fresh and be able to create a new data source with the same name.

When you replace the placeholders in the great_expectations.yml file you need to replace the stores not edit them. There should be no base directory in the TupleS3StoreBackend if you follow the instructions to edit the yaml files. Thank you

Thank you Georgios for your help!!

I have now fixed my issues.

For anyone having the same issue with Great Expectation yml file, the Jupytor notebook doesn’t make it explicit but we need to replace all the base_diretory under ExpectationStore, ValidationsStore, CheckpointStore and SiteBuilder with prefix .
