`LLVM=1 BERT_SIZE="tiny" DEFAULT_FLOAT=HALF BENCHMARK=5 MODEL="bert" python3 examples/mlperf/model_train.py` runs for me with this. it should not failed with single device shard though
* move cast to before softmax in attention
saved some memory because exp (which is used for backward) are done in half. training bert seems fine and can fit BS=78 now (from 66)
* test
* boom
* fix webgpu
* use exact variable names in test so that AI can read easier
* add tag for specific test name like test a specific dtype
* fix ruff
* astype everything
* dtype in array creation
* just arange
* is 67% considered fixed?
* move test up
* small cleanups
* share function
* add qgemm as well
* add qgemm too
* make sure qgemm comes out as int
* take out qgemm for now
* fixed test
* add correct qgemm
* addressing feedback here too, early naive fix for now
* simplify bias and c to be minimalistic enough to test correctness
* refactored qlinearops
* maybe these asserts aren't the best..
* fix test
* updated tests to cover new ops
* try to add to CI
* move test_onnx_ops into testextra/
* more attention tests
* qlinear_add atol=1
* attention still not fullllllly correct
* it is what it is
