Why does this file exist? ------------------------- Scalars are used to index subtensors. Subtensor indexing is the heart of what looks like the new scan mechanism. This little file made it possible to catch up to the Python interpreter in benchmarking tests. We don't want to encourage people to use scalars (rather than 0-d tensors), but the reason is just to keep the docs simple, not because scalars are bad. If we just don't register this shared variable constructor to handle any values by default when calling theano.shared(value) then users must really go out of their way (as scan does) to create a shared variable of this kind. i(tabsolute_importtprint_functiontdivisionN(t integer_types(tSharedVariablei(tScalart_scalar_py_operatorssJames Bergstras (c) 2010, Universite de Montreals3-clause BSD Licenses(theano-dev srestructuredtext entScalarSharedVariablecB`seZRS((t__name__t __module__(((s7/tmp/pip-build-X4mzal/theano/theano/scalar/sharedvar.pyR!sc C`s¸t|tjtttfƒs*tƒ‚ny |j}Wn#tk r\tj |ƒj}nXt |ƒ}t t|ƒ|ƒ}t d|ƒ}t d|d|d|d|d|ƒ}|S(s™ SharedVariable constructor for scalar values.
