Minimum reproducible example if you are using your own code, please provide a short script that reproduces the error. ## Steps to reproduce or if you are running standard examples, please provide the commands you have run that lead to the error. 1. Compile Mxnet and copy the libmxnet.dll to ~/mxnet/R-package/inst/libs/x64 2. R CMD INSTALL --no-multiarch R-package ## What have you tried to solve it? 1. Get familiar with R-package first to understand how to pass additional object to R command. 2. 3. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
