MXNET in R(3.5.2) MacOS (10.15.4)

I am trying to install mxnet for R on MacOS (10.15.4). I installed openblas 0.3.9 and opencv 4.2.0_3.

cran <- getOption(“repos”)
cran[“dmlc”] <- “
options(repos = cran)

and I get the following error:

[1] “Loading local: inst/libs/”
Error: package or namespace load failed for ‘mxnet’:
.onLoad failed in loadNamespace() for ‘mxnet’, details:
call: dyn.load(“R-package/inst/libs/”, local = FALSE)
error: unable to load shared object ‘/Users/Stefanos/R-package/inst/libs/’:
dlopen(/Users/Stefanos/R-package/inst/libs/, 10): image not found
