Ishitori commented on issue #13731: Contrib Symbol API of MXNet in R? URL: https://github.com/apache/incubator-mxnet/issues/13731#issuecomment-450216929 At this moment your best bet would be to use [reticulate](https://blog.rstudio.com/2018/03/26/reticulate-r-interface-to-python/) package to use python version of MXNet. I haven't tried mxnet.symbol.contrib, but my test autograd example seems to work fine: ``` library(reticulate) mxnet_python <- import("mxnet") x <- mxnet_python$nd$array(c(1, 2, 3, 4)) x$attach_grad() mxnet_python$autograd$set_recording(T) y <- mxnet_python$nd$sqrt(x) mxnet_python$autograd$set_recording(F) y$backward() print(x$grad) ``` ``` [0.5 0.35355338 0.28867513 0.25 ] <NDArray 4 @cpu(0)> ``` The syntax doesn't look as nice as original R client, but it works. So, just `pip install mxnet`, then in R `install.packages('reticulate')` and then use functions from Python replacing `.` with `$`.
