"Unhashable type" error while preprocessing using BasicPreprocessor

[kasramsh]

Describe the Question

Hi! I am trying to use your awesome package for document-retrieval. Tried to run toy examples in tutorial to get my hands on but actually it didn't run as expected.

Using BasicPreprocessor, I get a "TypeError: unhashable type: 'list'". As seen in the attached images, right before using the preprocessor, my data looks exactly as shown in the tutorial. What could be the issue? my MZ version is 2.2.0

PS: I am using matchzoo on Amazon AWS SageMaker (conda_tensorflow_py36 kernel). Could it be a problem by any chance?

Thanks in advance and good luck with the great job!

Hi guy, I think i got the same problem just like you... the Unhashbale list problem is not only limited to the BasicPreprocessor...
