Since nearly one year, I have been using
WinPython + JupyterLab + Julia 1.5.2
I can’t remember how I managed to configure that at that time.
Using JupyterLab that came with WinPython, I can create
Julia 1.5.2 notebooks.
I can use both languages side-by-side, which is very convenient.
Today, I installed
Julia 1.6.5 and I added the IJulia package from the REPL.
I expected to see a configuration
WinPython + JupyterLab + Julia 1.5.2 + Julia 1.6.5.
But nothing has changed!
Julia 1.6.5 doesn’t appear in JupyterLab.
I can use
Julia 1.6.5 by lauching JupyterLab from the REPL, but then my Python environment is gone.
Could you help me ?
I would like to use my existing Python environment and the
Julia 1.6.5 together
Can you try
At least in normal Jupyter this adds the new Julia version as kernel.
I did that and then
This launches a JupyterLab instance from the
Julia 1.6.5 folder.
The nice thing is that both versions of Julia are available.
Unfortunately, I have no acces to WinPython then.
Instead it takes Python from
...\.julia\conda\3 which is fresh new.
I would prefer to use my former WinPython installation with all my stuff!
The JupyterLab packaged with WinPython makes
Julia 1.5.2 avaliable.
I can’t remember how I did the install one year ago.
How does a JupyterLab instance know where all the kernels are?
In the documentation is something mentioned
Does that help somehow?
Just had a look at Installation · IJulia
I notied a remark about
ENV["JUPYTER"], and was quite exceited!
I then did this:
ENV["JUPYTER"] = "...\\WPy64-3940"
Unfortunately, it didn’t change anything.
But I have the feeling I come close to the solution !
I go to bed, and hopefully I solve that tomorrow !!!
Any suggestion again welcome!
Woke up early today!
But not yet a solution!
ENV["JUPYTER"] = "...\\WPy64-3940\\Jupyter Lab.exe"
does not solve the problem …
In the WinPython distribution, I observe there is a notebook called
But it looks like it deals with a very olde version of Julia.
And this script is rather obscure to me, I am not ready to go futher!
Any suggestion still welcome!
This seems to say similar things to what you tried, but maybe something useful?
Comes close, but no clue for my issue.
I got it !!!
Thanks to all of you !
I found out that the usual IJulia installation from the Julia REPL
kernel.json file in a folder like :
This where JupyterLab will look for kernels when it is started from the Julia REPL.
But the JupyterLab included in WinPython won’t look there.
Instead, it looks in a folder like :
I simply solved the problem by copying the
julia-1.6 folder from the first location to the second.
And now, I am happy!
