[WIP] See if we can make symbolic values default#2795
Draft

tested by test_set_grad_enabled
test: thunder/tests/test_core.py::test_integer_isinstance_mimicry
grad_transform_on_trace creates a cycle in the proxy names of tensor shapes. Specifically, it translates tA = prims.cat([tB, tC], -1) # "meta f32[..., iX]" (..., iX) = prims.shape(tA) into ta = prims.cat([tb, tc], -1) # "meta f32[..., ix]" (..., iX) = prims.shape(ta) This creates a translation ix -> iX. This leads to a cycle when the transform also produces iX -> ix. Repro: thunder/tests/test_jit_general.py::test_litgpt_variants[meta-long-context-like]
Fixes thunder/tests/test_grad.py::test_phantom_grad_vs_torch_consistency_var_mean_nvfuser_cuda_thunder.dtypes.float32

FYI: the intention for Q4 is to enable symbolic values for thunderfx, not for thunder.jit. |
