Question on the vocabulary size

[PPPPPsanG]

Emu3 is a good work, but i have some question on it.
The vocabulary size of Qwen is 152064 , while the codebook size of vision tokenizer employed in Emu3 is 32768
The addation is 184832, the vocabulary size reported in Emu3 is 184622.
Why do the numbers not match?
