Hi, I found this message while looking for a solution to this same error message. I am using theano 0.9 and python 3.5.
The error I get is: "In() instances and tuple inputs trigger the old " NotImplementedError: In() instances and tuple inputs trigger the old semantics, which disallow using updates and givens when trying to compile: self.train_fn = theano.function([input_var, target_var], [loss, out], updates=updates) where input_var is actually a Python list of 3 tensor variables of the same shape. Could this be the reason for this error? Are lists supported as type of input variables? Thanks, Francesco On Friday, February 24, 2017 at 9:43:17 PM UTC+1, nouiz wrote: > > What is the running code?
