Short of better line numbers (which we all want), a useful trick that often
works is to put `@show L` at the top of your loop; this will reveal which L is
causing the problem. Then, comment out the loop and just set L to this value.
More generally, you're doing a lot of computation at the

In my (generally functional) code, I frequently find myself asking for An
object like X but with Y different, eg. that image but with the
background set to transparent or that dataframe but with all inactive
customers' profit set to 0. The usual idiom is:
img2 = copy(img)
img2[img2.==black] =
Hi,
Suppose I have:
s = slider(1:10)
img = @lift eye(s)
How can I create the interactive plot in Jupyter using @lift?
@lift imshow(img)
I know @manipulate has the withfig() option where we can pass the PyPlot
Figure object, what about @lift?

Jim, are you porting DMRG code from Matlab to Julia?
Hi Shashi, thank you very much for your help.
What is slider_val in your code snippet? I actually have multiple sliders
and other widgets that I want to play with before plotting. Is there any
version of @manipulate where I can pass all sorts of widgets at once?

Hi Shashi,
When I type:
s = slider(1:10)
a = @lift eye(s)
display(s)
fig = figure()
@manipulate for a=a; withfig(fig) do
imshow(a)
end
end
I get the interactive plot correct, but an extra undesired print of the
array in Jupyter. What I can do to fix that?
-Júlio
I got it, the widgets are shown automatically by @manipulate, I'm changing
the code already.
Thanks,
Júlio.
