when I run the demo.py of faster rcnn, I get this problem,who knows how to solve it?Thank you very much!

I do not use mac to run this project. Just a guess.... Maybe you do not add the demo image path to your path.....

Hi, same problem and I am also using MAC, any idea to solve it?

[riadhayachi]

i think that you have a problem with caffe installation
try to go to py-faster-rcnn/caffe-fast-rcnn /python/caffe
open python and import caffe
i think it will send you the same error
it that correct reinstall caffe (go to caffe oficial site to see how to install caffe in mac)

Hi, I am using Mac OS X 10.12.6 and have met similar issues as mentioned above.
@fujingling @Dshinji137

This is the wrong output. I am working on a python virtual environment called "fasterRcnn". My Mac user name is ysh.

I have been stuck for a while until I found a similar issue here. BVLC/caffe#3597

First step:
(fasterRcnn) ysh@16:41:50@~/Projects/py-faster-rcnn/caffe-fast-rcnn$ otool -l -v python/caffe/_caffe.so | grep caf
python/caffe/_caffe.so:
name python/caffe/_caffe.so (offset 24)
name libcaffe.so.1.0.0-rc3 (offset 24)

Second step:
(fasterRcnn) ysh@16:47:37@~/Projects/py-faster-rcnn/caffe-fast-rcnn$ install_name_tool -change libcaffe.so.1.0.0-rc3 @rpath/libcaffe.so.1.0.0-rc3 python/caffe/_caffe.so

Result of second step:
(fasterRcnn) ysh@16:48:06@~/Projects/py-faster-rcnn/caffe-fast-rcnn$ otool -l -v python/caffe/_caffe.so | grep caf
python/caffe/_caffe.so:
name python/caffe/_caffe.so (offset 24)
name @rpath/libcaffe.so.1.0.0-rc3 (offset 24)

Third step:
(fasterRcnn) ysh@16:48:12@~/Projects/py-faster-rcnn/caffe-fast-rcnn$ install_name_tool -add_rpath /Users/ysh/Projects/py-faster-rcnn/caffe-fast-rcnn/.build_release/lib python/caffe/_caffe.so

Result of third step:
(fasterRcnn) ysh@16:49:02@~/Projects/py-faster-rcnn/caffe-fast-rcnn$ otool -l -v python/caffe/_caffe.so | grep caf
python/caffe/_caffe.so:
name python/caffe/_caffe.so (offset 24)
name @rpath/libcaffe.so.1.0.0-rc3 (offset 24)
path /Users/ysh/Projects/py-faster-rcnn/caffe-fast-rcnn/.build_release/lib (offset 12)

As you can see, the commands
install_name_tool -change libcaffe.so.1.0.0-rc3 @rpath/libcaffe.so.1.0.0-rc3 python/caffe/_caffe.so
install_name_tool -add_rpath /Users/ysh/Projects/py-faster-rcnn/caffe-fast-rcnn/.build_release/lib python/caffe/_caffe.so
add the path to the libcaffe.so.1.0.0-rc3 lib.

The command
otool -l -v python/caffe/_caffe.so | grep caf
shows the lib status.

Everything solved.

Please pay attention to the directories where you use these commands. Your faster R-cnn folder directory might differ from mine.
