使用 Coolprop 6.4.1 生成 p-h 图时的 warnings.warn

如何解决使用 Coolprop 6.4.1 生成 p-h 图时的 warnings.warn

运行脚本时显示：

using PyCall
pyimport("sys").executable
@pyimport CoolProp.CoolProp as CP
@pyimport CoolProp.Plots as CPP 
#=UNIT_SYstemS = {'EUR': <CoolProp.Plots.Common.EURunits object>,'KSI': <CoolProp.Plots.Common.KSIunits object>,'SI'
=#

plot = CPP.PropertyPlot("R410A","ph",unit_system="KSI")
plot.title("R410A log p-h Diagramm")
plot.set_axis_limits([90,550,15000])
plot.xlabel("h kJ/kg]")
plot.ylabel("P [kPa]")
plot.calc_isolines(num=15)
plot.show()

我收到了很多警报；其中一些示例：

       ...

你能告诉我为什么这个警报到期以及如何解决这个问题吗？
