Fix ProcessRaisedException
in PyTorch
✅ Solution
ProcessRaisedException in PyTorch often arises from issues within multiprocessing contexts, specifically related to CUDA device handling or argument mismatches during distributed operations or within TorchInductor. Ensure CUDA devices are correctly initialized and visible to all processes, and verify that all function/class calls within multiprocessing conform to the expected argument count and types as defined by PyTorch or TorchInductor APIs, paying special attention to distributed configurations.
