TokenClassificationExplainer Example does not work (LIGAttributions receives unexpected keyword argument "target")

[pharnisch]

Hello, I want to use the TokenClassificationExplainer. But when I run the example from your README.md, I receive the error

Traceback (most recent call last):
  File "trans_int.py", line 14, in <module>
    word_attributions = ner_explainer(sample_text, ignored_labels=['O'])
  File "/vol/fob-vol7/mi19/harnisph/ti/transformers_interpret/explainers/token_classification.py", line 296, in __call__
    return self._run(text, embedding_type=embedding_type)
  File "/vol/fob-vol7/mi19/harnisph/ti/transformers_interpret/explainers/token_classification.py", line 264, in _run
    self._calculate_attributions(embeddings=embeddings)
  File "/vol/fob-vol7/mi19/harnisph/ti/transformers_interpret/explainers/token_classification.py", line 234, in _calculate_attributions
    n_steps=self.n_steps,
TypeError: __init__() got an unexpected keyword argument 'target'

After debugging I saw, that the constructor of LIGAttributions receives target=7 and in the class itself it has an argument target: Optional[Union[int, Tuple, torch.Tensor, List]] = None, so I dont understand why it struggles with this argument as it is obviously there and should also be a valid value type.

Maybe someone can help me to understand/fix this. Thank you in advance.

Hi @pharnisch thanks for flagging this with me, can I ask what version you are using. There had been some bugs with versions 0.7.0-0.7.4 with the new explainer which I have fixed now. I just ran the readme example for token classification in a fresh environment and it seems to work for me.

Thank you for your fast response. Indeed, the problem could be due to versioning since I could only install version 0.6.0, but when I try to install the newest version, it does not work:

ERROR: No matching distribution found for ipython<8.0.0,>=7.31.1

I have installed:
Python 3.6.15 (cannot change this sadly)
Pytorch 1.10.2+cu113
transformers 4.17.0
Captum 0.3.1

When I get it correct, my Python version is not high enough to install a high enough ipython package but then the required Python version standing in the README.md is not right as I fulfill all of these four criteria.

Anyway, I just created a fork and removed the ipython dependency and now it works for my case. Thanks you! :)
