AttributeError: 'pymc3' object has no attribute 'switch'

Hey, thanks for the transition to pymc3!
There's probably a typo in the 8th cell in Intro Chapter
Should lambda_ = pm.switch(tau >= idx, lambda_1, lambda_2) be lambda_ = pm.math.switch(tau >= idx, lambda_1, lambda_2) instead?

Thanks! CC @mmargenot

Yeah, that looks like it is due to a more recent change in the package.

Both
lambda_ = pm.math.switch(tau >= idx, lambda_1, lambda_2)

and
import theano.tensor as tt
lambda_ = tt.switch(tau >= idx, lambda_1, lambda_2)

should work.

Closed by #321 .

Thanks!
