object conversion error

[long-feng]

Hi Ian,

I'm trying to use DiskJockey on a more powerful server. DiskJockey tests passed using Pkg.test("DiskJockey"). However, when I try to make structure, the error : ' LoadError: MethodError: Cannot convert an object of type String to an object of type Float64' prevents me going further.

All the things go smooth with my desktop, also in Linux system, but with a older version of Julia (v0.4).
I'm not sure if this error is something related with Julia updates?

I copied the output here, and ignored many warnings.

Thanks!
Feng

Hi Feng,

There are a few things that might be causing this error. The main thing that jumps out is that it looks like you are using Julia v0.5 on the server, while the current version of DiskJockey in the github repository master branch is only for v0.4. However, I did recently upgrade the development version to v0.5, so you can try obtaining that by doing the following on the server.

$ cd /home/longfeng/.julia/v0.5/DiskJockey
$ git pull
$ git checkout devel

This should put you into the development version of DiskJockey, which is for Julia v0.5.

The other thing that might cause this error is if you happen to have a typo in your config.yaml file, particularly when entering the parameter values. Things such as entering integers (e.g. M_star : 1) or double decimal points (e.g. M_star : 1.0.0) by accident have caused similar errors for me.

I think the WARNING: deprecated syntax "[a=>b for (a,b) in c]". notifications are coming from some of the packages that DiskJockey depends on, so once these are upgraded to v0.5 these should go away.

Please let me know if this fixes the issue.

Hi Ian, It turns out that it’s my own mistake! I made the mistake when changing the initial parameter value. Thanks for all of this! Feng
