Tried to install forecastHybrid with install.packages(forecastHybrid) and got these errors

Error: package or namespace load failed for ‘forecast’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/usr/lib/R/library/uroot/libs/uroot.so':

$ locate libcudart

I have cuda-9.2 and libcudart.so.9.2 instead of 9.1

OS is Ubuntu 16.04, R version 3.5.1

@beew This doesn't look to be a problem with the "forecastHybrid" package but rather loading its requirement "forecast". And the problem there is actually loading its dependency "uroot".

I haven't done anything with CUDA setup, so I can't help you there. You've probably seen this already, but maybe it helps https://cran.r-project.org/web/packages/uroot/README

I see. I thought uroot would be pulled in as a dependency automatically. I installed uroot first and now it works. Thanks.
