I want to create an IJulia notebook with a Julia kernel using 64 cores, so based on the IJulia documentation I ran this:

```
julia> IJulia.installkernel("Julia -p64", "-p64")
INFO: Installing Julia -p64 kernelspec julia--p64-0.6
Error executing Jupyter command 'kernelspec': [Errno 'jupyter-kernelspec' not fo
und] 2
ERROR: UndefVarError: Conda not defined
Stacktrace:
 [1] #installkernel#4(::String, ::Function, ::String, ::String, ::Vararg{String,
N} where N) at C:\Users\arbenede\.julia\v0.6\IJulia\src\..\deps\kspec.jl:87
 [2] installkernel(::String, ::String, ::Vararg{String,N} where N) at C:\Users\a
rrigo\.julia\v0.6\IJulia\src\..\deps\kspec.jl:36

```

I verified that Conda is installed and I also rebuilt IJulia.

Any ideas?

Thanks!
