Example DeeplabV3 not works

[Armin234]

Hi,

the example on the site https://nnabla.readthedocs.io/en/latest/python/api/models/semantic_segmentation.html didn't work.

I always get the error: AttributeError: 'NoneType' object has no attribute 'shape'

Thank you for pointing it out. Please let us check.

[TomonobuTsujikawa]

Now https://github.com/sony/nnabla/pull/1049 was merged, so you can run this model with latest code. (nnabla v1.27.0 doesn't contain this change, so next nnabla release (v1.28.0?) will be needed if you use official release)

I think this issue was resolved, so please let me close.
