example does not work under Julia >= 1.0

[obviousnic]

I made some obvious syntax changes to get the example to run under julia 1.3/Knet 132,
but it fails with this error

Hi, can you please share more details about the problem, and the full notebook you are working on?

[obviousnic]

Helo, thank you   I am attaching a notebook that shows the problem. In this notebook I modified your code to remove the obvious syntax errors fur julia1+.   It produces the autograd related error when it gets to the last cell, when running under Julia1.3.   (Under Julia1.02, the version of imagenet.jl that it finds is not updated to julia1+, so there are additional errors there).   I had also tried to modify to use the newer @diff style autograd interface, which did not work either (I think it gave the same erorr).     Sent: Tuesday, December 31, 2019 at 1:31 AM From: "cemilcengiz" <notifications@github.com> To: KnetML/Neural-Style-Transfer <Neural-Style-Transfer@noreply.github.com> Cc: obviousnic <obviousnic@gmx.com>, Author <author@noreply.github.com> Subject: Re: [KnetML/Neural-Style-Transfer] example does not work under Julia >= 1.0 (#3) Hi, can you please share more details about the problem, and the full notebook you are working on? — You are receiving this because you authored the thread.

Hi, apparently you failed to attach the notebook. Can you try adding the code to the comment or sharing it with gist instead?

[obviousnic]

  Oh sorry for that.   Now it is attached I hope :)   Sent: Sunday, January 05, 2020 at 7:14 AM From: "cemilcengiz" <notifications@github.com> To: KnetML/Neural-Style-Transfer <Neural-Style-Transfer@noreply.github.com> Cc: obviousnic <obviousnic@gmx.com>, Author <author@noreply.github.com> Subject: Re: [KnetML/Neural-Style-Transfer] example does not work under Julia >= 1.0 (#3) Hi, apparently you failed to attach the notebook.

Nope, I have still not received it. Maybe, attachment is not supported for github issue replies via e-mail.

[obviousnic]

That is strange. Yes I guess attachments are not possible.   Anyway, it is easy to see the problem. Just try to run your notebook inside Julia1.3  (or any >= 1.0), there are several problems.   Some are just syntax changes from 0.6, but the autodiff error I cannot figure out.       Sent: Saturday, January 11, 2020 at 8:14 AM From: "cemilcengiz" <notifications@github.com> To: KnetML/Neural-Style-Transfer <Neural-Style-Transfer@noreply.github.com> Cc: obviousnic <obviousnic@gmx.com>, Author <author@noreply.github.com> Subject: Re: [KnetML/Neural-Style-Transfer] example does not work under Julia >= 1.0 (#3) Nope, I have still not received it.
