Re: [julia-users] Pyplot and type definitions

2016-04-27 Thread Steven G. Johnson

IJulia doesn't support the workspace() command 
(https://github.com/JuliaLang/IJulia.jl/issues/226); just restart the 
kernel (in the "Kernel" menu) instead.

As for the warnings, you get them if you just do "using BinDeps; 
workspace(); using BinDeps", so the warnings themselves aren't specific to 
IJulia.

Thanks, posted an issue on 
github: https://github.com/stevengj/PyPlot.jl/issues/210.

I was testing it in IJulia, that's where I got all the warnings. At the 
REPL I don't get them unless I write:

using IJulia
workspace()
using PyPlot

I can reproduce. Even just

workspace()
using PyPlot

yields most of the above warnings. It's probably a problem in Base, but I 
would file an issue with PyPlot.

I cannot make sense of these warnings but you need to either import + from 
Base or explicitly use Base.(:+)
when overloading.

Re: [julia-users] Pyplot and type definitions

2016-04-26 Thread samuel . huberman

In my jupyter notebook, sequentially, I define types:

workspace() # needed for redefining type
type State
position::Int
spin::Array{Any,2}
State() = new(0,[1 0]')
State(position,spin) = new(position,spin)
end

and functions on types

function +(s1::State, s2::State)
#Linear combination
if s1.position == s2.position
s=State(s1.position,s2.spin+s1.spin)
return s
else
return [s1,s2]
end
end

then when I call

using PyPlot

the warnings are (I get no plots, only PyObject 
)

It's hard to help without seeing your code, and more complete output.

[julia-users] Pyplot and type definitions

2016-04-26 Thread samuel . huberman

Hi,

I'm trying to use PyPlot in a Jupyter notebook (Julia 0.4.5). I have some 
type definitions and I have some functions that overload functions from 
Base (i.e I define the + operator on my new types). When I try to call a 
plotting function after these definitions, I just get something like

PyObject 

with no plot displayed. 
If I declare "using PyPlot" after my type definitions, I get lots of 
warnings like:

Method definition remotecall(Function, Main.Base.LocalProcess, Any...) in 
module Compat at /Users/.julia/v0.4/Compat/src/Compat.jl:822 overwritten in 
module Compat at /Users/.julia/v0.4/Compat/src/Compat.jl:822.


So I guess my type definitions and overload functions are interfering with 
PyPlot. Any ideas how to fix this?
