我在Julia中使用“ PyPlot”包来绘制高斯图形，遇到了一些错误。我试着不绘制小雕像，没有错误。所以我认为PyPlot可能有问题。
这是我的代码：
using GaussianRandomFields, PyPlot
using Random, Printf, PyCall
pygui(true)
A = [1 0.8; 0.8 1]
an = AnisotropicExponential(A)
cov = CovarianceFunction(2,an)
pts = range(0; stop=10, length=512)
grf = GaussianRandomField(cov,KarhunenLoeve(500),pts,pts)
contourf(grf)
display(contourf(grf))
我得到了这个结果：

有人可以帮忙解决它，谢谢。
