Description

While using tokenizers.create with the model and vocab file for a custom corpus, the code throws an error and is not able to generate the BERT vocab file

Error Message

ValueError: Mismatch vocabulary! All special tokens specified must be control tokens in the sentencepiece vocabulary.

To Reproduce

from gluonnlp.data import tokenizers
tokenizers.create('spm', model_p

Somewhat related to #1724 but it's also useful for skills to be able to get a list of all joined (not just configured) rooms.

I am thinking a signature like:

def joined_rooms(self, encrypted_only=False):

which returns room_ids for the rooms. Richer nio room objects could then be obtained by doing connector.connection.rooms[room_id].
