kindly someone help

Hi,

It seems that the number of corpus weights is different from the number of corpus. Please check config file.

https://github.com/clovaai/synthtiger/blob/master/examples/synthtiger/config_horizontal.yaml#L16 This example has two corpus (length augmentable corpus, char augmentable corpus) and two corpus weights (1, 0).

Sorry, can you guide what to change, im trying to generate greek images from corpus, im using this config file, i change the weight but i dont know why still getting the same error
