after modification it works well upto page 3 but I had another bug on prediction/forecasts due to depreciation of ix and I modified .ix to .loc but the plot still looks no lower and upper bound.
Third bug happened when I tried Metropolis-Hastings-ARIMA (1,1) and for some reason I had problem with installation with pymc nonetheless of my successful records on installation with pip.
However, Gibbs codes run well.
My last bug was found at the last box titled "Construct the predictions / forecasts" This is same as my second bug and I had no lower and upper bound line on my plot and followings are error message for your information.
Happy New Year and thanks for your excellent implementation on MCMC and TSA.
