Errors with sampling

Thank you! I have another problem,I’m wondering how PyMC pass parameters to a called function . In my problem, when I creates t,I I hope to create a array with a central value of mu.But when I pass mu to numpy, I get errors, so I create t use

    t_min=0
    t_max=(t4_s.shape[0])*(t4_s[1]-t4_s[0])
    num=t4_s.shape[0]    
    t=np.linspace(t_min,t_max,num)

instead.But I think this may cause problems in my data processing process.
