python - Setting deterministic distributions in PyMC3 -


i'm new pymc3 here pymc2 - need specific compile in theano convert pymc3 code? 

 @pymc.deterministic     def away_theta(home_team=home_team,                     away_team=away_team,                     home=home,                     atts=atts,                     defs=defs,                     intercept=intercept):          return np.exp(intercept +                        atts[away_team] +                        defs[home_team])

i error like

astensorerror: ('cannot convert home_theta tensortype', <class 'pymc.pymcobjects.deterministic'>)

yes, determinstic transformations need theano expressions in pymc3. instead of using np.exp you'd use theano.tensor.exp:

import theano.tensor t import pymc3 pm  model():     ...     regression = pm.deterministic('regression', t.exp(intercept + atts[away_team] + defs[home_team]))     ...
