WebJan 15, 2024 · A is a float tensor with shape (batch size, hidden dim). B is a Long tensor with shape (batch size, data len). What I want is somewhat like A [:, B], a float tensor still with shape (batch size, data len), the elements are certain indices from A which depends on B. An example would be A= [ [5, 2, 6], [7, 3, 4]] and B= [ [0, 2, 1, 1], [2, 2, 1, 0]].

WebTorchInductor uses a pythonic define-by-run loop level IR to automatically map PyTorch models into generated Triton code on GPUs and C++/OpenMP on CPUs. TorchInductor’s core loop level IR contains only ~50 operators, and it is implemented in Python, making it easily hackable and extensible.
