DensityDist conditional random() method

Thanks,
I tried that but:

current_epoch_values = draw_values(current_epoch_shared)

throws:


  File "/home/bdyetton/PSleep/src/modeling/sleep_stage_models.py", line 208, in _random
    current_epoch_values = draw_values(current_epoch_shared)
  File "/home/bdyetton/anaconda3/envs/psleep/lib/python3.7/site-packages/pymc3/distributions/distribution.py", line 283, in draw_values
    params = dict(enumerate(params))
  File "/home/bdyetton/anaconda3/envs/psleep/lib/python3.7/site-packages/theano/tensor/var.py", line 628, in __iter__
    for i in xrange(theano.tensor.basic.get_vector_length(self)):
  File "/home/bdyetton/anaconda3/envs/psleep/lib/python3.7/site-packages/theano/tensor/basic.py", line 4828, in get_vector_length
    raise ValueError("length not known: %s" % msg)
ValueError: length not known: <TensorType(int64, vector)> [id A]

Giving a size input to draw values does not help either.
