Pyplot crash on window
A short PyPlot program is crashing on my Windows 11 machine (i.e., the Julia REPL exits with no error message). I verified that it works correctly on Linux. This is Julia 1.9.3, PyPlot 2.11.2. The data file br1copy.txt [br1copy.txt](https://github.com/JuliaPy/PyPlot.jl/files/13823984/br1copy.txt) is attached.
module readbr1
using PyPlot
function readbr(filename, stepnum)
ststepnum = string(stepnum)
it = zeros(Int,0)
res1 = zeros(0)
res2 = zeros(0)
open(filename, "r") do h
while true
p = readline(h)
s = split(p)
if length(s) < 12 || s[1] != "step" || s[3] != ststepnum
if eof(h)
break
else
continue
end
end
itnum = parse(Int,s[6])
push!(it, itnum)
#println(itnum)
push!(res1, parse(Float64, s[9]))
push!(res2, parse(Float64, s[12]))
if eof(h)
break
end
end
end
return it, res1, res2
end
function makeplots(it, res1, res2)
figure(1)
clf()
semilogy(it, res1)
figure(2)
clf()
semilogy(it, res2)
nothing
end
it, res1, res2 = readbr("br1copy.txt", 6)
makeplots(it, res1, res2)
end
This issue occurs on a particular Windows machine but not others, so it may be difficult to reproduce.
On the same Windows 11 box I created a new user test_julia, downloaded Julia 1.10.0 from scratch, installed PyPlot from scratch, and encountered the a crash as soon as I typed figure(1). There were a few warnings during the PyPlot installation and build (see below), but none of them appear serious.

julia> figure(1)
C:\Users\test_julia>
I'm experiencing the same issue, also on Windows 11. I have tried Julia v. 1.6.7 and v. 1.10.0, and reinstalled everything several times, but I get the same issue every time. Matplotlib works fine when called from Python. I also tried a different user on the same PC but got the same result. For me, this issue happened after I reinstalled Windows 11 (and Julia and Python); before that, everything was working perfectly.
I got it to work for me. My best guess is that something goes wrong when PyPlot uses Conda to install Matplotlib. So here is what I did to make it work:
- Install Python (check the box to add it to PATH)
- Install Matplotlib as described here: https://matplotlib.org/stable/users/installing/index.html
- Check that Matplotlib works in Python
- Add an environment variable named "PYTHON" that links to the exe-file of the Python version from steps 1 through 3.
- Install Julia
- Check that
ENV["PYTHON"]in Julia returns the path to the python exe-file from step 4. - Add PyPlot in Julia
After that, when typing using PyPlot it should not start installing Matplotlib through Conda, but just return. Running figure() should open an empty figure without crashing.
Did you try:
ENV["PYTHON"]=""
Pkg.build("PyCall")
This installs a version of Python and Matplotlib for Julia only and thus avoids compatibility issues with versions installed outside of Julia.
I tried both of the solutions mentioned in the two previous posts (installing Python and Matplotlib "manually" and then installing the PyPlot package, followed by using PyPlot and figure(1)), and also not installing Python at all and building PyPlot, but neither worked. I am still getting a crash as soon as I type figure(1). Does anyone know if there is a log file written somewhere before Julia crashes? I should mention that I seem to see a figure window flash briefly on my screen before the crash, so PyPlot seems to be active. I'll add that Matplotlib invoked from Python seems to be working.
Have you tried switching to a different Matplotlib backend? (e.g. set ENV["MPLBACKEND"]="TkAgg" or ="QtAgg" or ="GTK4Agg" before loading PyPlot).
Try using the same backend that you are using from Python, as printed by matplotlib.get_backend().
I retried the solution of manually installing Python and Matplotlib, setting the Windows environment variable PYTHON, and then reinstalling Julia and PyPlot. It didn't work yesterday, but it worked today. The difference between what I did yesterday versus today is: yesterday I partially cleaned out Julia and PyPlot; today I fully cleaned them out (uninstall julia and delete the entire .julia folder). So this problem is solved for me, and I will close the issue.
