when I run demos it appears problem like this:

TypeError: ('An update must have the same type as the original shared variable (shared_var=W, shared_var.type=TensorType(float32, matrix), update_val=Elemwise{sub,no_inplace}.0, update_val.type=TensorType(float64, matrix)).', 'If the difference is related to the broadcast pattern, you can call the tensor.unbroadcast(var, axis_tounbroadcast[, ...]) function to remove broadcastable dimensions.')_

and I use theano 0.9.0.

Same issue here. Also using theano 0.9.0
