kandi X-RAY | Sypy Summary

Sypy is a Python library typically used in Utilities, Interpreter applications. Sypy has no bugs, it has no vulnerabilities and it has low support. However Sypy build file is not available. You can download it from GitHub.

Sypy: A symbolic execution engine for Python. Sypy leverages PyPy's interpreter to interpret Python bytecode and generate constraints. These constraints are solved using Microsoft's Z3 SMT solver. Currently Sypy generates constraints for if statements involving integer values. While booleans, longs and floats have symbolic support they have not been tested yet. Function evaluation has not been tested yet. Besides, supporting arbitrary functions is probably not a good idea. The most appropriate way would be to determine all possible return values of a function and substitute those values in the constraints. The most important thing to do right now is to interleave symbolic execution code in the binary operations.

QUESTION

Tensors in sympy?

Asked 2019-Apr-04 at 14:36

I want to use sympy to build a cython callable for evaluating a loss/jacobian/hessian. The loss function (defined as a python function due to lack of latex on SO) is as follows

I ended up abandoning Sympy as it was more trouble than its worth. If you want to do some automatic differentiation I'd recommend using tensorflow which is what I ended up going with. Below is the script for creating the hessian of the equation (7).
