Hi,

first of all, thanks for these wonderful repository and tutorial. I have an isse, though. When i run the script i get this error code: 'Indexing with integers (to access backend Encoding for a given batch index) is not available when using Python based tokenizers'

Do you know why it is happening?

To recreate the issue, i did the following:

cloned the repository python src/train.py

Thanks
