Fix InductorError

in PyTorch

Solution

InductorError often arises when symbolic shapes or strides used in inductor's internal calculations result in SymPy Relational objects where a boolean value is expected. Fixing this involves either simplifying the symbolic expressions to concrete values when possible, or restructuring the code to avoid boolean evaluation of symbolic relations by utilizing `torch.fx.proxy.Proxy` or `torch.compile` graph breaking appropriately. Ensure input shapes do not depend on control flow when using dynamic shapes to help Inductor resolve shapes concretely.
