fastai.text do not have the ModelData module

[fooSynaptic]

hello @alesee , i follow the document of your rep and run the jupyter notebook of abstractive-text-summ.ipynb to create modelData which stick the datasets to a single object. but the fastai.text do not have the ModelData module.

NameError Traceback (most recent call last)

in ----> 1 model_data = ModelData(SAMPLE_DATA_PATH, trn_dl=train_iter_tuple, val_dl=val_iter_tuple) NameError: name 'ModelData' is not defined can you give me some advices to handle this problem? or i need the check the subsequent program and write a function by myself? thank you !

You may need to manually define the version of the fastai library. I used an older version: 0.7. Good luck! Reach out to me on Twitter (@omarsar0) if you continue with any issues.
