No updates to `self.logits` with bigram counts in Bigram class

Hello everyone, i've made a `makemore.py` file (same as https://github.com/karpathy/makemore/blob/master/makemore.py) with only Bigram model class as of now.

while running it with `python makemore.py -i names.txt -o names --type bigram` arguments, wouldn't it just keep training, where it actually isn't doing anything coz there is no operation in forward pass.

Has anyone succesfully run it? Or it is yet to be completed?
