Why I cannot plot with pymc3.traceplot or arviz.plot_trace?

[Jym0502]

az.plot_posterior is also unavailable.
Result is as follow:

Only array without pictures.

I wonder how can I find the plots to prove my views.

I think you need to show it:

import matplotlib.pyplot as plt
import arviz as az

# build model and sample here

az.plot_posterior(my_trace)

plt.show()

Check out the documentation for usage details.

Thank you. The usege of arviz is different from pymc3.traceplot.
