Code not working

[chrisdottel]

Code references a custom_dataset module that doesn't exist. Removed it. Then I get this ghost parameter

test.py: error: the following arguments are required: --dataroot

There seems to be no description to what this parameters is for. Passing it in blank we get

TypeError: Can't instantiate abstract class Pix2PixModel with abstract methods optimize_parameters

Did anyone work through all of this to get the base pretrained model working?
