Question: running the Tutorial failed (fixed)

[yinchenhe]

I was trying to run the tutorial, but it failed. Following is the message I got.

Welcome to the PyCFTBoot tutorial! Please read the comments and watch for coloured text. Which theory would you like to study? These take increasingly long amounts of time.

1. 3D Ising model (even sector only).
2. 3D O(3) model.
3. 3D Ising model (odd sector as well).
4. 4D N = 1 supersymmetric model. Choice: 1 Finding basic bound at external dimension 0.518... Trying 1.2 SDPB started at 2017-Sep-06 22:47:30 SDP file : "mySDP.xml" out file : "mySDP.out" checkpoint in : "mySDP.ck" checkpoint out : "mySDP.ck"

It is fixed now. It seems that I didn't install symengine.py properly.

Glad to hear it.
