Hi @Sandy4321 , have tried to uncomment the line the unzips the dataset in the previous cell?

# unzip the dataset, if you haven't already done it
# ! unzip datasets/sessions..zip -d datasets

great now I do have this il\data_utils.py:24: FutureWarning: using a dict on a Series for aggregation is deprecated and will be removed in a future version. Use named aggregation instead.

>>> grouper.agg(name_1=func_1, name_2=func_2)

aggregated = groups['item_id'].agg({'sequence': lambda x: list(map(str, x))})

though I get this

is it correct?

That looks right. As for the warning above, it might be due to the newest versions of pandas, but it should be easy to fix.
