This error also happens with other files in the examples directory. Using julia 0.5.

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.

[ozanarkancan]

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

[youssefzaky]

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