input_ids = tokenizer.encode(prompt, return_tensors='pt')

                             temperature=1.0,
                             top_k=50,

for i in range(5):
  print(tokenizer.decode(outputs[i]))

Most likely outputs (Disclaimer: I highly recommend using this over just generating):

prompt = """few sights are as [blank] new york city as the colorful, flashing signage of its bodegas [sep]"""
text = tokenizer.encode(prompt)
myinput, past_key_values = torch.tensor([text]), None
myinput = myinput
myinput= myinput.to(device)
logits, past_key_values = model(myinput, past_key_values = past_key_values, return_dict=False)
logits = logits[0,-1]
probabilities = torch.nn.functional.softmax(logits)
best_logits, best_indices = logits.topk(250)
best_words = [tokenizer.decode([idx.item()]) for idx in best_indices]
text.append(best_indices[0].item())
best_probabilities = probabilities[best_indices].tolist()
words = []   
print(best_words)
