some issue in `joint.py`

[junhocho]

Trying joint.py insteady of mergan.py, also facing problem.

First, the deconv2d module not found bug, this was handled by adding import tflib.ops.deconv2d in gan32_model.py.

Even then, I am facing following error

Traceback (most recent call last):

Any help? It would be great help to reproduce your work and make the code runnable from clean slate. Thank you!
