J of DTCWTInverse doesn't work

[FeiSong123]

Traceback (most recent call last):
  File "py_dtcwt.py", line 24, in <module>
    ifm = DTCWTInverse(biort='near_sym_b', qshift='qshift_b', J=3)
TypeError: __init__() got an unexpected keyword argument 'J'

The code is:

ifm = DTCWTInverse(biort='near_sym_b', qshift='qshift_b', J=3)

The api guidance of DTCWTInverse list J as parameter, however, when I tried it in the code, it didn't work. And when I go to see the source code, it didn't even define it.
