free() invalid pointer when using UpROOT PythonPlot

[alusiani]

The following minimum example code

using UpROOT
using PythonPlot

fails with:

free(): invalid pointer
signal (6): Aborted

Julia 1.7.3
UpROOT v0.3.3
PythonPlot v1.0.0

I guess it should be related to both packages calling Python.

UpROOT.jl uses PyCall. This is incompatible with PythonCall. You should use it with PyPlot, not PythonPlot.

[alusiani]

The fault comes from an incompatibility between PyCall and PythonCall, which can be fixed by getting:

ENV["JULIA_PYTHONCALL_EXE"] = "@PyCall"

see PythonCall Tips.
