Hi !

When I execute the first code from this page : [https://julialang.org/downloads/plotting.html](https://julialang.org/downloads/plotting.html) , i get thie error message. Can you help me ? Because I get this error message on adding lots of packages

Can you post the output of:

```julia
using Pkg
Pkg.status()

```

?

That will help us figure out what’s going on.

Hm, that all looks fine. From your original post, it looks like something is wrong with the source code of the Compat.jl package–did you edit that by hand at some point? You may be able to resolve the issue by deleting `~/.julia/packages/Compat` and then re-running:

```julia
using Pkg
Pkg.add("Compat")

```

So if you just add Compat without deleting then what would happen ?

Sorry for the answer time.

I’ve deleted and then readded Compat. The adding has worked right, and I relaunch `julia test_plot.jl` which is the program whose code is in the link I’ve given above, and … I get an error (after at least one minute) telling me that I have to rebuild `Conda`. I’ve done, and I do same for `PyPlot` and `Plots`.  
And now, that takes really long time to run, but I get this warning message :

┌ Warning: `getindex(o::PyObject, s::AbstractString)` is deprecated in favor of dot overloading (`getproperty`) so elements should now be accessed as e.g. `o."s"` instead of `o["s"]`.  
│ caller = top-level scope at none:0  
└ @ Core none:0

but that seems working right. But now, when I run this :

`julia> using Plots`  
`julia> plotly()`  
`Plots.PlotlyBackend()`  
`julia> plot(rand(5,5),linewidth=2,title="MyPlot")`

That plots nothing, what did I do wrong ?

And, I’ve a question : `using Plots` takes long time (between two and ten seconds), is it normal ?

Thanks for all replies ! =)

I am also facing this warning. This warnings is appearing in case of skcore.jl line 120 and line 158.

If you use the GR backend by running `gr()` instead of `plotly()` is there any difference?

And yes, the slow start-up for plots is unfortunate but expected. There is a lot of work being done now on tools like PackageCompiler to improve the situation, but it’s not a fully solved problem yet.

There was a recent update in the PyCall API — a bunch of Julia packages that use Python via PyCall will see deprecation warnings for a little while until they are updated. Plots.jl was just fixed, but SciKitLearn has not been updated yet:

> <https://github.com/cstjean/ScikitLearn.jl/issues/52>
>
> PyCall 1.90.0 is now released, which change \`o\[:foo\]\` and \`o\["foo"\]\` to \`o.foo\` …and \`o."foo"\`, respectively, for python objects \`o\`; see also JuliaPy/PyCall.jl#629.
> 
> The old \`getindex\` methods still work but are deprecated, so you'll want to put out a new release that uses the new methods and REQUIREs PyCall 1.90.0 to avoid having zillions of deprecation messages.

Is there any other way to call Python in Julia? I mean other than using PyCall. Apologies if this appears to be silly question.

Well, you could run the `python` executable through a pipe. For example, the IJulia package can launch the Python `jupyter notebook` program, and used to require `jupyter` command-line program to build in order to get the Jupyter version and install the kernel specification file, but it never used PyCall.
