Erroneous documentation for Normal

[thomas-haslwanter]

The function "pm.Normal" uses the keyword "sd". However, all the documentation gives examples with the keyword "sigma" - which crashed the current version of pymc3 (3.6) E.g. (Documentation):

import pymc3 as pm

X, y = linear_training_data()
with pm.Model() as linear_model:
    weights = pm.Normal('weights', mu=0, sigma=1)
