Logical error in train.py

[monisha08041998]

Hi Iam facing error for dataset_name, dataset in personachat.items():

num_candidates = len(dataset[0]["utterances"][0]["candidates"])

    num_candidates=2
    if args.num_candidates > 0 and dataset_name == 'train':
        num_candidates = min(args.num_candidates, num_candidates)
    for dialog in dataset:
        persona = dialog["personality"].copy()​
        for _ in range(args.personality_permutations):
            for utterance in dialog["utterances"]:
                history = utterance["history"][-(2*args.max_history+1):]
                for j, candidate in enumerate(utterance["candidates"][-num_candidates:]):
                    lm_labels = bool(j == num_candidates-1)
                    instance = build_input_from_segments(persona, history, candidate, tokenizer, lm_labels)
                    for input_name, input_array in instance.items():
                        datasets[dataset_name][input_name].append(input_array)
                datasets[dataset_name]["mc_labels"].append(num_candidates - 1)
                datasets[dataset_name]["n_candidates"] = num_candidates
            persona = [persona[-1]] + persona[:-1]  # permuted personalities

in this part of the train.py and also have anyone tried to train it with your own data.Please guide the steps

Hello, can you teach me how to understand these sentences?
