Wrong number of words in assignment 1

[inverb]

In task 2 from assignment 1 it says that ws should " Build a dictionary of most frequent 20000 words." Yet in all of the 8529 sentences there are only about 18000 distinct words. Should that number be 2000?

[janchorowski]

No, I didn't count the words and wanted to somehow limit the number. For the last point you can check the influence of vocab size.
