Boost Error
Hi,
I tried installing your converter, but I keep on running into the following error:

Makefile:30: recipe for target 'mxnet_to_caffe' failed
make: *** [mxnet_to_caffe] Error 1
Is this an issue with my boost installation? My caffe install seems to be working fine though. I am working off of the latest caffe pull.
Any ideas? Thanks for the help!
It seems that boost-python needs to be linked. Try to add -lboost_python to the CAFFE_DEPENDENCES in the Makefile, and please let me know if it works to update it.
Thanks for the response. I added -lboost_python to the Makefile but ran into the same error. I then tried installing boost from source, remaking caffe, and then running make but I get the following:

Thanks for the help!
Ok, it seems from your Makefile that boost was not installed using apt-get or other package managers, but directly downloaded to a folder boost_1_62_0 and compiled there. The most straightforward solution to fix this problem is to install all required libboost-dev using apt-get instead.
However, if you wish to keep boost in a folder, you can try to add also -lboost_system and the path to that folder adding -DBOOST_DIR="boost installation location" to the CAFFE_DEPENDENCES.
This error may also arise if there is already a Boost install in /usr/lib/ that will be incompatible with your self-installed Python (https://github.com/GalSim-developers/GalSim/issues/270).
Hello,
I tried adding the -DBOOST_DIR flag, but I get the same error.
I also tried using a boost install from apt-get to see if that works instead. Unfortunately, I get the same error when using libboost-dev from apt-get.
I ran sudo apt-get install libboost-all-dev to install boost.
I then recompiled caffe to use that boost install instead of the boost version I downloaded to a folder.
Here is the error I get when running make to install this converter using apt-get boost:

Any ideas? Not sure why I'm still getting this undefined reference error. Thanks for the help!
The Caffe Makefile has the following definition:
PYTHON_LIBRARIES ?= boost_python python2.7
So I would try to add -lpython2.7 (or the version you have) to the CAFFE_DEPENDENCES. If you can't find it, check this link: http://stackoverflow.com/questions/8400272/usr-bin-ld-cannot-find-lpython2-7. The linking order matters, so it should be included after boost_python.
