Hi,
first time using PyCall and I’m having problems generating plots with the Python package that I’m trying to use, but I’m not sure how to debug it.
The Python package I want to use is called ChiantiPy (GitHub - chianti-atomic/ChiantiPy: ChiantiPy is a python package to calculate the radiative properties of astrophysical plasmas based on the CHIANTI atomic database)
In Python I just do (popPlot generates a figure):
import ChiantiPy.core as ch
import numpy as np
import matplotlib.pyplot as plt
t = 10.**(5.8 + 0.05*np.arange(21.))
fe14 = ch.ion('fe_14', temperature=t, eDensity=1.e+9, em=1.e+27)
fe14.popPlot()
In Julia I tried something similar:
using PyCall
ch = pyimport("ChiantiPy.core")
np = pyimport("numpy")
plt = pyimport("matplotlib.pyplot")
t = [10^i for i in 5.8 .+ 0.05 .* range(0.0,20.0,step=1)];
fe14 = ch.ion("fe_14", temperature=t, eDensity=1.e+9, em=1.e+27);
fe14.popPlot()
plt.show()
But when I run it, I get first this error about libGL, though I don’t think that is important?
julia> include("test.jl")
found PyQt5 widgets
using PyQt5 widgets
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
then, a new window is created, where the figure should go, but no figure is shown. If I try to close it, then I get a warning from the system that “This window might be busy and is not responding. [etc]”.
If I close this window and later I try to generate the plot again via popPlot() then julia itself dies:
julia> fe14.popPlot()
The X11 connection broke: I/O error (code 1)
XIO: fatal IO error 22 (Invalid argument) on X server ":0.0"
after 483 requests (481 known processed) with 0 events remaining.
Any suggestions on how to get this working properly?
Thanks,
AdV
