Pyimport crashes VSCode Julia REPL

Importing the Python module Scipy instantly crashes and closes VSCode Julia REPL before I can see the error message.

For instance, the following code crashes my REPL every time:

julia> using PyCall
julia> mv = pyimport("scipy.stats.mvn") 

Interestingly, importing the module Math does not crash my REPL:

julia> using PyCall
julia> math= pyimport("math")
PyObject <module 'math' from '/Users/gaston/.julia/conda/3/lib/python3.10/lib-dynload/'>

In VSCode, I am using:

Version: 1.84.2 (Universal)

And I have v1.60.2 of the Julia language extension. This is all on MacOS Big Sur 11.6 (M1, 16GB)

Does that happen in the terminal too (just trying to get VSCode out of the equation)?

It does.

Calling Scipy it crashes:

julia> using PyCall
julia> pyimport("scipy")
zsh: killed     /Applications/
Saving session...
...copying shared history...
...saving history...truncating history files...
Deleting expired sessions...none found.

[Process completed]

while calling the module Math it does not crash:

julia> pyimport("math")
PyObject <module 'math' from '/Users/gaston/.julia/conda/3/lib/python3.10/lib-dynload/'>

Julia Version 1.9.4

It is probably worth checking that you are using the right Python version with scipy installed. Try typing ENV["PYTHON"] at the Julia REPL command line and see what Python it’s pointing too and make sure it’s the one you want.

Side note: I think it is generally recommended to use the PythonCall.jl package these days rather than PyCall.jl.


Making use of the PythonCall package instead of PyCall solved the issue!

I am not sure why but now the Julia REPL does not crash (nor in the terminal).

Thanks for hinting this out.
