@tgsmith61591 thank for your reply
I have four years history daily data, I want to predict the data for the next 90 days by pyramid.
When i used pyramid i don't know how to set the arima parameter m

Also, potential duplicate of #12. If the docs don't solve your issue, take a look at the issue thread and the linked (in the thread) example ipynb.
