AttributeError: 'module' object has no attribute 'Net'

[Alonso Ali Goncalves]

Hello everyone. My old Caffe build was all messed up so I decided to do a fresh install of Caffe on my Mac OSX 10.12 (Sierra). Did it with no errors during make (make all, runtest, pycaffe and distribute). After the whole setup process I tried to run a simple python -c "import caffe" to make sure everything was working but to my surprise I'm getting a wall of text of errors and warnings. After a little research it seems those warnings can be ignored, but the main problem is "AttributeError: 'module' object has no attribute 'Net'". Anyone knows what's up with this? I wasn't able to find an explanation online to this. The whole error is:

dyld: warning, LC_RPATH @executable_path/ in /usr/local/cuda/lib/libcublas.8.0.dylib being ignored in restricted program because of @executable_path

dyld: warning, LC_RPATH @executable_path/ in /usr/local/cuda/lib/libcurand.8.0.dylib being ignored in restricted program because of @executable_path

Thank you.

Hi,

could you solve this issue?

I get a similar error from my code: 

module 'caffe' has no attribute 'Classifier'

I think these two can be solved the same way.
