Description

I have installed mxnet following the steps on the web: https://mxnet.apache.org/versions/master/install/index.html?platform=MacOS&language=R&processor=CPU

When I try to load mxnet library via library(mxnet) I have the following error:

 .onLoad failed in loadNamespace() for 'mxnet', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so':
  dlopen(/Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so, 10): Library not loaded: /usr/local/opt/opencv/lib/libopencv_stitching.3.4.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so
  Reason: image not found

I noted that the reason was I haven't got the file libopencv_stitching.3.4.dylib and then I have create manually all the symbolic link needed via

Finnally, when I try to load mxnet package I have the error:

Error: package or namespace load failed for ‘mxnet’:
 .onLoad failed in loadNamespace() for 'mxnet', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so':

and I don't know what more to do :(
