AttributeError: 'SeqGANInstructor' object has no attribute 'train_data' about textgan-pytorch

I had the same issue. It turns out to be an issue with my dataset.

To overcome this, I modified the following in utils/text_process.py:

def tokens_to_tensor(tokens, dictionary):
    tensor = []
    for sent in tokens:
        sent_ten = []
        i = - 1
        for i, word in enumerate(sent):
            if word == cfg.padding_token:
                break
            sent_ten.append(int(dictionary[str(word)]))
        
        sent_ten = sent_ten + (cfg.max_seq_len + 1 - i)*[cfg.padding_idx]
        
        tensor.append(sent_ten[:cfg.max_seq_len])
    return torch.LongTensor(tensor)

Tensor was a list with list of dynamic size. This ensures all list are of the same size, even if the list is empty.

Do you put the comment.txt file into the dataset directory? The self.train_data needs to load the dataset file you specified in the config.py file (parameter dataset), but it seems there is no file named dataset/comment.txt.

I have received same error, when I changed the dataset. Even I have placed dataset file in dataset folder.

raceback (most recent call last):

    inst = instruction_dict[cfg.run_model](opt)

and have you sloved this problem now？I have the same problem

I solve it ,maybe the dataset has some problem.

Hi, I have the same problem with catgan.py. I modified text_process.py as you suggested, but then another error appears:

File "/home/sc.uni-leipzig.de/ie870xetu/TextGAN-PyTorch/instructor/real_data/catgan_instructor.py", line 63, in __init__
    self.all_train_data = CatGenDataIter(self.train_samples_list)
`AttributeError: 'CatGANInstructor' object has no attribute 'train_samples_list'`

has some problem.

How did you solve your problem?

I am also getting the same error.
AttributeError: 'CatGANInstructor' object has no attribute 'train_samples_list'
How to resolve it ?
