Dvc exp run --temp fails when dvc exp run succeds

Bug Reports
1

Hey,

atm I have the problem that both dvc exp run --temp as well as running experiments via the queue fail but running them normally succeeds.

In the first case I get the following error:

dvc exp run --temp
ERROR: unexpected error - Duplicate keyword name at line 13.

Running it in the queue I get following output in the celery worker out file:

I have the same error in a different repository as well, after updating dvc

anyone know to which file this error refers to? ERROR: unexpected error - Duplicate keyword name at line 13. It cant be the params.yaml file because dvc repro works fine…

Hi, sorry for late response.

There is some duplicate keys in your .git/config. This is a bug in DVC, because dvc uses configobj to parse git config and apparently, git allows duplicate keys while configobj does not.

For now, I’d suggest checking .git/config and remove duplicate keys from line 13.
