I am encountering a program crash with the following error message:

Welcome to the community!

What is the output of

```julia
versioninfo()

```

What is the output of:

```julia
using Pkg
Pkg.status()

```

?

Apart from some precompilation warnings I could add these packages to a new project on Linux, so the packages are nor broken.

You are using PyCall, which might use your local Python installation (outside of Julia), which could cause issues.

To do a fresh Python installation specific for Julia, please try:

```julia
ENV["PYTHON"]=""
Pkg.build("PyCall")

```

restart Julia, and try:

```julia
using PyPlot

```

Does that work?

I am calling Julia functions from Python using Pyjulia. After doing the code you mentioned, I could not launch Julia from Python with this error:

It is not really clear to me what you actually want to do.

- do you want to use Python from Julia, e.g. by using PyPlot?
- do you want to use Julia from Python?
- do you want to use both?

Doing one of these things should be easy, doing both is not easy… You then need either two different Python environments, or you need to use only packages for both scenarios that are compatible…

Can you explain in more detail what you actually want to do, and which Python packages and which Python environment(s) you want to use?

Please read: [Is PyJulia org, e.g. juliacall (or pyjulia) Python packages maintained?](https://discourse.julialang.org/t/is-pyjulia-org-e-g-juliacall-or-pyjulia-python-packages-maintained/109277)

In theory you can use either `PyJulia`, or `juliacall` for this purpose. PyJulia is the old way of doing it (and might break easily), and `juliacall` the new way of doing it, but I never used any of these two packages, so I cannot give any advice on this topic.

You can undo this:

```julia
ENV["PYTHON"]=""
Pkg.build("PyCall")

```

by restarting Julia and running:

```julia
Pkg.build("PyCall")

```

But if that helps you to fix your current problem, I don’t know. I never used Julia from Python, only the other way round…

From the conda environment you sent me it seems you have a mix of packages from pypi and conda.

You might try building the environment completely from conda-forge components. Specify `-c conda-forge` when creating a new environment.

I recommend going with `juliacall` rather than `pyjulia`.

I am using `juliacall` instead now. Seems like this fixes the problem.
