I am unable to install the SparseArray package in Julia 1.1.0 . I am getting the following error message. This is a very basic package needed in any application that deals with large data.

Thanks. I installed that package, but the command speye() does not seem to be working.

Because it has been deprecated.
I assume that you are working from some outdated script/docs. At this point you may benefit from
1. reading the fine [manual](https://docs.julialang.org/en/v1/stdlib/SparseArrays/),
2. looking at the [deprecations](https://github.com/JuliaLang/julia/blob/v0.7.0/NEWS.md) (or, optionally, [using 0.7 for the transition](https://discourse.julialang.org/t/psa-use-julia-0-7-if-you-are-upgrading/13321))

Thanks again. For new users like me, it is really difficult to track depreciations in new versions. But I guess many features of Julia are still in development.
For the moment, spzeros(n,n) is working fine for me.

FWIW, Julia 1.0 was the first _stable_ version, and allowing changes to the API was [implicit](https://semver.org/) in the 0.\* versioning. Now in 1.x there should be very few breaking changes.

Hi
using SparseArrays; x = speye(4)

Please read the discussion above; `speye` was deprecated.

I highly recommend following @Tamas_Papp’s advice. Upgrading from pre-1.0 to 1.x is _so much easier_ if you use version 0.7. That’s why we made it!
```julia
julia> VERSION
v"0.7.0-rc2.0"

WARNING: Base.speye is deprecated: it has been moved to the standard library
package `SparseArrays`.
Add `using SparseArrays` to your imports.

`SparseMatrixCSC{Float64}(I, m, n)`. If `Float64` element type is not necessary,

Use julia 0.7 when upgrading not 1.1.0. Julia 0.7 gives you deprecation messages that tell you how to upgrade, just like @mbauman showed you.

For Julia 1.1.0, how can we call Sparse identity matrix function? I need a command in terminal.

Try use julia 0.7 and use `speye`, it will tell you how to do it because julia 0.7 has deprecation warnings. Julia 0.7 is good when upgrading code. It is better to use julia 0.7 first because it will tell you what the replacement is for upgrading code.

is there a external _package_ for Sparse identity matrix function in Julia?

Sorry, our responses have probably been cryptic for someone coming from Matlab or Numpy (and not upgrading from an old Julia version)!
You just need to use both LinearAlgebra and SparseArrays:
```julia
julia> using SparseArrays, LinearAlgebra
julia> sparse(1.0I, 3, 3)
3×3 SparseMatrixCSC{Float64,Int64} with 3 stored entries:
[1, 1] = 1.0
[2, 2] = 1.0
[3, 3] = 1.0
```
It looks like you already defined `I` to mean something different in your current Julia session. We’re referencing `LinearAlgebra.I`. This will do the same (and skirt around a shadowed binding for `I`):
```julia
julia> sparse(1.0*LinearAlgebra.I, 3, 3)
3×3 SparseMatrixCSC{Float64,Int64} with 3 stored entries:
[1, 1] = 1.0
[2, 2] = 1.0
[3, 3] = 1.0
```

Hey, no problem, some time it looks very like matlab coding!
Thanks a lot for your support!
