Please make sure you are running the latest Knet version using Pkg.update()
and Pkg.build("Knet"). Let me know the output of Pkg.status() if the
problem persists.

I updated Knet to 0.8.1 and that error is gone. However I'm getting another one from running:
julia linreg.jl

Did you Pkg.build("Knet") to recompile libknet8?

Yes its says libknet8.so is up to date. I also did Base.compilecache("Knet") but still the same problem.

I couldn't replicate the problem with the fresh install.
Please check whether Knet.libknet8 is set to the correct location:
using Knet
Knet.libknet8
If it prints empty string
Try to delete Knet.ji which is located under $JULIA_PKGDIR/lib/v0.5/ .
And build the lib again:
make clean
make
in $JULIA_PKGDIR/v0.5/Knet/src

I reinstalled julia and Knet and it works fine now. Not sure what went wrong before.
