wittyalias opened a new issue #14004: unable to load mxnet library in R URL: https://github.com/apache/incubator-mxnet/issues/14004 Possibly related to the issues in [#13952](https://github.com/apache/incubator-mxnet/pull/13952). I've followed the [instructions ](https://mxnet.incubator.apache.org/versions/master/install/index.html?platform=MacOS&language=R&processor=CPU) to install CPU version of MXNet for R on MacOS (10.14.2). I successfully install openblas (0.3.5) and opencv (4.0.1) via brew using ``` brew install opencv brew install openblas ``` Also, added the symbolic links as suggested (this is a different openblas version that I have installed): ``` ln -sf /usr/local/opt/openblas/lib/libopenblas.dylib /usr/local/opt/openblas/lib/libopenblasp-r0.3.1.dylib ``` And then installed the package within R with: ``` cran <- getOption("repos") cran["dmlc"] <- "https://apache-mxnet.s3-accelerate.dualstack.amazonaws.com/R/CRAN/"; options(repos = cran) install.packages("mxnet") ``` ## Description When I try to load the mxnet library I get an error message below ``` >library(mxnet) 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': dlopen(/Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so, 10): Library not loaded: /usr/local/opt/openblas/lib/libopenblasp-r0.3.1.dylib Referenced from: /Library/Frameworks/R.framework/Versions/3.5/Resources/library/mxnet/libs/libmxnet.so Reason: image not found ``` ## Environment info (Required) I'm using R in RStudio 1.1.463 ``` R version 3.5.2 (2018-12-20) Platform: x86_64-apple-darwin15.6.0 (64-bit) Running under: macOS Mojave 10.14.2 Matrix products: default BLAS: /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib LAPACK: /Library/Frameworks/R.framework/Versions/3.5/Resources/lib/libRlapack.dylib locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods [7] base ``` ## What have you tried to solve it? 1. My guess is that its looking for different versions of openblas and opencv than I have installed, so I tried to install a previous versions of them via brew, but I can't figure out how to do it for openblas and 3.4 opencv installs to a folder 'opencv@3' - so the library won't be able to find it anyway. I did not change the symbolic link because before I had the openblas 0.3.1 error, I had a very similar looking error that said it couldn't find opencv 3.4. I was thinking of cloning the repository and seeing if I could change what openblas and opencv versions mxnet looks for, but that seems like a lot of work for something that you may already be looking into.
