Hi George.
A way to avoid the error is by using lists of grids, where each grid
only has valid combinations
param_grid = [{'dual': False, 'penalty': 'l1', 'C': 10. ** np.arange(-3,
3)}, {'dual': True, 'penalty':'l2', 'loss': 'l2', 'C': : 10. **
np.arange(-3, 3)}]
or something like that. (Look up the allowed combination in the docs, I
don't know them by heart ;)
What are you searching over? Searching over whether to use the dual or
not does not really make much sense to me.
Best,
Andy

I'm trying to perform a grid search cv for logistic regression but I
stumble on invalid combination of parameters:
ValueError: Unsupported set of arguments: penalty='l1' is only
supported when dual='false'., Parameters: penalty='l1', loss='lr',
dual=True
Is there a way to avoid this problem?
Thanks,
George.
