Building Knet fails in 1.5.1

[philtomson]

I tried building Knet with Julia 1.5.1 and got:

I had moved the Project.toml from .julia/environments/v1.4 over to .julia/environments/v1.5 and this seems to have been the cause of the problem. I started over without a Project.toml in v1.5 and it seems to build fine.

I found that Knet 1.4.1 works with Julia 1.5.1, but Knet 1.3.7 did not build. As I added packages to my 1.5.1 Julia installation, I found that after I added CuArrays, Knet was downgraded to 1.3.7 and again failed to build again:

So seems like some kind of interaction between CuArrays version and Knet version requirements.

Hi Phil, CuArrays has been superseded by CUDA.jl, you do not need to include it any more.

Yes, I found this, thanks. I think the advice to copy the v1.4 Project.toml to v1.5 is probably not the best, but this seems to be what is advised when updating to a newer version of Julia.
