Hello, I encountered a bug while reproducing your experiment. As indicated in the title, an argument --small_kernel_merged: Boolean value is expected. I have checked, and the parameter received by small_kernel_merged is of type str, and its lowercase value is indeed 'false', but the condition v.lower() in ('no', 'false', 'f', 'n', '0') still evaluates to False. This results in the error message mentioned above.
