Hi Guys!
I am trying to go through the tutorial [here](https://github.com/KnetML/Neural-Style-Transfer/blob/master/neural_style_transfer.ipynb).
But I am getting the error:
```julia
Cannot find libknet8, please rerun Pkg.build("Knet").
Stacktrace:

```
On running ‘Pkg.build(“Knet”)’ I am getting this:
```julia
INFO: Building Knet
WARNING: no compilers found, libknet8 will not be built.
INFO: Compiling Knet cache.
```
I am on Julia 0.6(Ubuntu 18). Can you guys tell me the issue. Thanks!

Try with Julia 1.0.

MAT still has not been tagged for Julia 1.0 but `using Pkg; pkg"dev MAT"` works.
