"AttributeError: 'dict' object has no attribute 'figure'"

When I run the example in the tutorial, (https://nbviewer.jupyter.org/github/SheffieldML/notebook/blob/master/GPy/basic_gp.ipynb), I get the error below. My matplotlib version is 3.3.4

# test
X1 = np.random.uniform(-3.,3.,(20,1))
Y1 = np.sin(X1) + np.random.randn(20,1)*0.05
kernel = GPy.kern.RBF(input_dim=1, variance=1., lengthscale=1.)
m1 = GPy.models.GPRegression(X1,Y1,kernel)
fig = m1.plot()
GPy.plotting.show(fig, filename='basic_gp_regression_notebook')

Hello.

Has this issue been resolved since it opened? The same error came up to me.

Thanks!

Thx, I have also fixed it as following:

import matplotlib.pyplot as plt

fig = m.plot(title='basic_gp_regression_notebook')
plt.show()
