Theano was a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. It is being continued as PyTensor: www.github.com/pymc-devs/pytensor
a = theano.tensor.vector("a")
b = a + a \ 10
f = theano.function([a], b)
print(f([0, 1, 2]))
[ 0. 2. 1026.]
