Question about MLP

[isentropic]

Here you are padding the tensor with special starting token. It looks strange to me that you are doing it inside the embedding. Isn't this strange?
Aren't you supposed to first pass the special token through the embedding first and then add that as a padding?

tok_emb = self.wte(idx) # token embeddings of shape (b, t, n_embd)
idx = torch.roll(idx, 1, 1)
# something like this instead?
idx[:, 0] = self.wte(self.vocab_size) # special <BLANK> token

embs.append(tok_emb)
